I've been running 22psi in the rear tires of my '21 Trike since new, passenger or not. Huge difference between 26 and 22. Learned this one day after installing my rear bumper, then stepping on it and bouncing to see how strong it was. I looked at rear tires and saw how stiff they still were when bouncing at 26psi and had a lightbulb moment! Totally made sense to drop the pressure. As you say, look at the loads of each tire.....Trike = 1350 lbs. There's got to be 350 lbs. on front tire leaving only 500 lbs. for each rear which is nothing for that size tire. Good video

I’ve always rode on 2 wheels. Due to a back injury that affects my legs I recently bought a 2012 triglide. Garage kept with only 1100 miles on it.I won’t give up riding. It’s nice to get info from someone who actually ride a trike all the time. I lowered my pressure in the rear tires to 20psi and it was an enormous difference in the comfort of the ride. Will be watching your videos for more updates I’d like to do to my trike. Thanks

Glad we watched this! Our trike tires will be 22 lbs before our next ride- maybe even 20. I really felt they were too firm at 26

I seem to remember you mentioned this in a previous video, but it’s great to listen to a discussion based on your experience plus some factual evidence, Fifty thousand miles out of any tire is pretty impressive. Now to go down to the garage to reset my tire pressures. I’m sure that my wife will thank you!🍺

Thanks for this discussion on tire pressures on Harley Tikes. I watched a similar video from another source. It did not give specific numbers, so I reduced my pressure to 24psi and could feel some improvement. I will play around with pressures starting at 22psi and see if that works for me. I usually ride solo and rarely load down my ride. This information could potentially safe riders from spending big bucks on upgrading their rear shocks. I ride is a 2021 Tri Glide Ultra.

I have only had my 2009 Tri-Glide for a couple years and have put several thousand miles on it so far doing improvements from watching videos and following your channel and 98% of the things I've changed, bought or done to my Tri-Glide has been because of the (way) yall research and explain your findings on a subject . So after watching this at 1am I went to the garage and checked my tires on this 55° night in south central ky and found front at 40 psi lowered it to 36 and rear were around 32psi and lowered to 22psi and went ripping around the block (15-16) miles at WOT as much as my country backroads will allow and MY experience was very delightful to my surprise 😮 😀 needed to test drive it really anyway because I had just installed the 606 and transformer EBS a few hours before and was wondering what my morning commute to work would bring so after watching this I couldn't TAKE NO MORE 🤣 so around the block I went 😁 so now i can't sleep because I'm watching the clock for my 27 mile morning auto tune session on the way to work😎

THANKS for that information !!! I have been following the Owners Manual since I bought my Trike new 4 years ago, but like you say the Dealer always jacks it back up to 36 when I take in for service. I now have 45K miles on my 2018 Trike Ultra and decided I am gonna keep the Trike rather than trade it in so I purchased Legends Suspensions on front and rear. The difference in comfort is worth the money to me .... and now I am going to lower my rear tire pressure to 20 psi for an even better ride. THANK YOU !!!

Thank you so much for this great info & all your other videos.

Great Video. First one I've heard on lowering rear tire pressure, but makes sense. Will lower to 20 psi the next time I go for a ride. Keep up the good work. Thanks.

Great video! Thanks for the information.

I sure am glad yall put this out. I just bought my second trike , and I've been running my pressure at 32 lbs because they were car tires. I'm on my way now to go riding, I will definitely be dropping that down to 22. She was a rough riding biddy

Thanks Ford and Firestone! When the government got involved we had more regulations! TPMS was one of the results. And some tire shops now will not mount your tires unless you replace the expensive sensors. Thanks for bringing this to everyone's attention.

I run 22 on my trike... made a huge difference in ride comfort. I might run it at 20. Great video. Thanks :-)

Thanks for having the guts to make this tire pressure video, lower is much more fun.

Thanks Guys.....I just need now to order the lifts and adjust the shocks...

Another great video. Thanks!

I ran 20 PSI on my 2017 and now on my 2021, and it does make a difference in the ride. I’ve not had any unusual wearing of the tires at all, nor has it adversely affected the handling of the trike. Good information, guys, and good discussion.

Thanks for the great info on tires. There is always discussion about tire pressure for the rears, and it goes from book pressure to what someone does personally. The video makes perfect sense when coupled with numbers. Keep up the great vids and info!!! 2023 Tri Glide Ultra is my ride.

Auto tech for 15-20yrs. If i recall, i remember reading a tsb or something back in the day. The reason for the lowerd pressure in the exploders was to help counter their tipy-ness. The placard in the doors, say 26 psi. I've delt with alot of tires over the years. you can tell when someone ran one too low on pressure, as the sidewalls begin to disintigrate. In mild cases, you'll see a slight bubbly deformation, in extreame cases, the sidewall completey destroys itself. Its all about the tire sidewall flexing and heating up. Think of bending a wire back and forth until it breaks. The other thing you'll see is if its so low, the rim rests on the tire and grinds the insides together, and rubs/wears/cuts through on the inside. Now my truck, wieghs 5400lbs. (I wieghed it, on a scale, so I knew what size winch would be apropriate.) Its reccomended tire pressures are 32 in the front, 35 in the rear.. why? Incase I haul stuff. keep in mind, the engine is in the front. the tranny and t-case are biased to the front. Its partly why front brakes are soo much larger than rear.. the fronts do 60-70% of the braking work... cuz inertia, wieght etc. I just bought my trike like 3 weeks ago... 6hr ride home.. lol. But I went past that scale, its a truck stop, and I needed a break, water, and to send my kid on his way home. (He drove me down to look at the trike etc.) The trike wieghs 1200lbs, )with my tackle box.. lol. 1410lbs with me on it. thats like 1/4 to 1/5th the wieght, only 1 less tire... My quad, i run at 14psi. Its alot lighter, but its theyre balloony light wieght tires, but i ride that thing sideways, skipping off tree roots and rocks, and bounced it off trees etc no problems, never blown a bead or nothing. Also, lower tire pressure, more contact to the road = more traction. Kinda like walking very flat footed on ice in the winter. "The penguin walk." lol I wouldnt be scared to run the trikes tires as low as even 18psi, or even lower. i have cars come in all the time in winter, tires not even 20 psi, doin fine, just low. (The average auto tire looses 1psi for evey 7 degrees celcius the temp drops. we go from +35 summers to -45 winters. thats like a 10-12 psi change throughout the year.) Everything you guys say makes so much perfect sense. Erm.. sorry I rambled ,Just wanted to share what I was thinking while you guys were discussing! Great vid!

Great channel .hoping you will find something to stop the wind above the lower farings on the triglide

thanks for the info i will be doing that on my freewheeler cause been useing max pressure being concerned with uneven wear and lower fuel milage due to the lower air pressure and my god it is like riding a 2 X 4 and just a back killer and i had gotten a trike cause of a lower back issue and was so disappointed with the harsh ride

Holy mackerel. You just busted my belief on 26 lbs. Wow! Thanks for your research and the video information.

Thanks for the info, been running 32 this whole time. Will correct that immediately!

Another get video very informative, I am looking to purchase a trik. Thanks again

I just got a 2018 Harley Davidson trike. I am watching all the videos for setup and safety. I have yet to learn all the controls and screen choices. I watch all your videos and when I am confused I ask the questions. Thanks for replying.

Just purchased a 2018 Checked the rear tires they were at 34psi. Will lower them before my next ride. Thanks

Interesting perspective on tire pressure for a Trike. I’m wondering what it does to your fuel mileage and whether your more susceptible to flat tires because of the low tire pressure.

Yes you are spot on. The CanAm recommends 12.5 to 17psi on the front tires, I recommend 15-16 max on my custom trikes. excessive pressure has a detrimental effect on handling. More pressure will result in bounce and ill handling in general. For ALL trikes 18-20 is max. Keep in mind however rear wheel trikes are inherently unstable due to design especially in hard braking while going downhill.

I changed my pressures yesterday to 18 lbs and had the most pleasurable ride to date on my trike. I also dropped my shock pressure down to 13 lbs which is a little low in “some” cases. I will increase 1 lb at a time and try to repeat the conditions again to get it just right. Also plan doing temperature checks on tires before and during the ride. Great information have bought a few products from DK and love them.

Great video guys, what do you recommend tire pressure for the front tire.

Thanks guys for the great information. I'm in Australia and have a 2018 Tri-Glide which I have found for me is 22psi for the rear types and the rear suspension is at 30psi. I'm often ride 2up and or with a trailer.

Good info tomorrow before we go riding, I'm lowering my rear tire pressure to 22psi to start. Normally my wife rides with me and our tour pack and trunk are loaded with everything we might need in case of weather issues.

Great video I could tell the tire pressure was to blame just didn't know where to put the psi .being a grey haired old man i needed a grey haired old man's advice 😀

Hey guys love your videos! My question for you is how bad does your mpg get at 20 psi? Fyi just bought a 2017 tri glide ultra

Good to know!

My 2015 Freewheeler rides hard. Converted to independent rear suspension and it helped a lot. The trouble is the front wheel. When I hit a bump it is rock hard. I'm thinking of increasing the triple tree rake set up. Any suggestions regarding this or another way to soften the front wheel impact hitting a bump. BTW, great video as usual.

Interesting information,I have a cvo triglide,what would you recommend for tire pressure,with a pillion passenger. Take care both of you,from the UK

Thanks

Dunflop..I love it!! Recently bought the Michelin Commander lll for my 15 Road King because the Dunlops just wern't giving me the mileage I expected. I'm running the same air pressure in the Michelins of 36 and 40 psi, but now think I might lower the front some to help improve ride. Running the Legend AXEO for about a year now, but still feeling the bumps more than I would like. Any "suggestions" would be appreciated. Maybe drop it down to 30 in the front? Thanks for the info, always look forward to your videos!

Picked my 2011 Tri Glide up yesterday and started heavy maintenance on it. Great video: will adjust TP today. Side note: 2011 model with 2070 miles on it. Verified by dealer with their scan tool.2070 miles.....Paid 17 grand for it. 2070 original miles. That would be 2070 miles. Did I mention it has 2070 original miles?

Wow. Just the video I was looking for. Been running 26 psi in both my 2012 and 2016 HD Trikes. Will lower to 20 in the rear. However, I do ride with a few other HD Trike guys and they sometimes run 36 to 40 psi in the rear tires when we are running hot. Their theory is a higher inflated tire will provide less roll resistance and get greater performance. Don’t know about that.

I had a FreeWheeler, TriGlide Ultra and now a 2022 TriGlide CVO. All rough riders. I’ve lowered the tire pressure as low as I could before the TPMS warning light comes on. I’m looking for the sweet spot using lower TP and mono shock setting. Any recommendations for one up? Two up? Thanks for the good videos.

The fight between Ford and Firestone came in that Firestone told the Ford engineers to run 28psi and the Ford people wanted to get a better ride and lowered the tire pressure to 24psi. The tires were popping off of the bead going flat while people were doing curves and turns. The rest is as they say history. After the lawsuits were done Ford increased the required pressure to 28 psi. Guess Firestone was correct. I am double checking on that 2015 Freewheeler that I rode. The tire pressure was set by a guy that was working with me. He watched a bunch of your videos before we started working on the trike. We put your brackets that raise the rear up on because of his watching that video.

I bought a 2016 freewheeler and it already had a lift kit and air shocks 26 lb buckboard ride. Lowered air to 24 lb still rough ride.

Great video! I dropped my rear to 21 and 33 on the front and a much better ride. Just ride smart to prevent tip overs. Could you do a video on the location of all ground connections on the trike? Having a difficult time locating them in all the spaghetti harnesses. Have a P0152 code and have replaced the sensor. Returns on a short ride after being cleared. One of the causes is a possible bad ground which is what I would like to locate and clean before thinking about replacing ECM. Thanks from Canada

Sadly, on the CVO tri glide running it lower than23 will trip the TPMS system. I have a 2019 Tri Glide Ultra and will run it at 20-22 now that I understand the situation. I will purchase a TPMS system that used valve cap sensors and be able to monitor it to stay safe. I ran one on my 2012 Street Glide and it uses the phone and you can set the alarms to be what you want. They measure pressure and tempeature and are less than $50.

Anyone have any thoughts about running aftermarket tp sensors? So you’ll always know at a glance what the pressure is?

The rear tires on my Freewheeler are the same size as the ones on my '06 Diesel Beetle. I ran those at 34psi front/30psi rear; in Las Vegas where I lived, they dry-rotted to death long before the tread was gone. But, that was a CAR. I knew the tire pressure in the Freewheeler's owners manual was... bogus... when I read it. So is the air pressure for the rear shocks, by the way... I've been running 20psi in them, since I bought the thing in April 2019. It's been all over the country, with lots of hard, hot miles in the Southwest. There's still almost no discernable wear on the things. If I'm loaded down with stuff, and going to be running around in the mountains with lots of time over 10,000 feet? Sometimes, I'll put 22psi in them, but no more. Probably not necessary, but... it make me feel good. I'm eyeing a set of Michelin radials for when these Dunlops finally die (don't care much for Dunlops), but at this rate? They just might outlast ME...

Love to see a dulley rear end

My 2023 road glide 3 has low profile tires and over sized rims From the factory. What do you recommend as to not ruin the tire or rim/ wheels? Pot holes are the roads in the capital city of michigan. I bought wheel and tire warrenty.

I run 24 pounds on our TRIGLIDE Two up , but will try 22 pounds thanks

Do you have a TPMS system on your trike? I was thinking of getting something to monitor tire pressure. I have aftermarket wheels (Coastal Moto) and lower profile tires (less sidewall as a result), I run 30 psi, but now I’m curious if I could run lower…🤔

What should the tire pressure be on 18 inch rear custom wheels on a Freewheeler?

How do you adjust the parking brake on a 2014 Harley TG

Any suggestions on the front tire psi?

What pressure do you recommend for the front tire on the trike?

A quick question for you, what do you set the pressure at when your wife us riding with you? I picked up my 2024 Tri Glide Ultra a couple weeks ago, I noticed the ride is better when my wife is with me as opposed to riding by myself, she weighs about 135 which clearly is not a big person.

What do you recommend tire pressure for the trike front tire

Hey Guys. What about the front tire on the tike. What pressure do you have on your trike.

I have a2018 triglide. i've set it up to pull an Little guy My Pod Camper. Right now the toung weight is 43 pounds. The trailer weighs 870lbs. what tire pressure. between 20-26.Don't go crazy in turns.

Do side car tires have the same issue? I was thinking about getting one.

What psi do recommend for trike w/ a passenger and full luggage?

I run the harley davidson custom 16 in wheel on my 2019 M8. Can I still run 22 psi in the rear tires.

my question is i have 2014 harley trike, the rear tires are those tires like a rear car tire 205/15 or is that tire a special tire for the trike. i want to put michellin tires on the trike.as of now i have the stock tire that they come with stock {brand}.and can you run 22 psi with wife and luggage. thank gunnery sergrant muniz.

2018 freewheeler should ride well at 22 with a passenger and minimal gear ?

gee i bought a ford explorer xlt last yr lol.

36 PSI you got away lucky, salesman tried to help service finish PDI as they were running behind on a busy day of deliveries, well long & short rear tires were set at 46PSI boing, boing, boing all the way home. The explanation "that is what the tire said to put in" from that day forward I have run 22PSI and never had an issue even at 30 degrees.

I run mine at 22 but I’m gonna try 20 now. How bout your front tire? What do you run yours at? I’m at 35 right now.

The stock PSI on the M8 Fat Boy is wrong too. The correct PSI for the Front and Rear of an M8 Fat Boy is 40 and 42PSI. The stock pressure is too low.

I can’t find the name of the extended warranty you had the person with a company that sale the warranty on your M8 road glide 2017 ? Can you please give me the name of the company??

I have a question when running The tire that low dose the front road Walk

I weigh 400 lbs .do.i need to add more psi to the tires than 20 or 22psi?

I have a 2018 trike with CVO rims and tires. I'm running Legend coil over shocks and their lift kit. Would 20 psi still apply for my trike? Thanks for the great information!

What about front tire pressure?

What about the front tire pressure!!

how about the front tire

What about the front tire .

I know if you run under pressure on a car the tires could over heat and could blow out. The tires over heated , air expanded, over pressure and blow out. Hot day 65 mph.

Rr

Thanks
