That is the first time I have heard this explained so well AND with links to manufacturers charts. You folks are great.

Wow! I initially didn't think it was going to be a good video (watched the first 2 minutes). But then I read some of the comments and saw some really positive ones. So, I restarted the video and really like your explanation. This is the best tire pressure explanation I've seen. Well done!! Tks!!

This is the first video that has made any sense and it almost anticipated my questions.

Great video and the information was full of details without being boring. Thanks for doing the homework and adding links with charts. I appreciate this video. Thank you.

Thank you! Been looking everywhere for this and this was super clear and straightforward.

Omg we’ve been doing this all wrong 🙈. It has been SO difficult finding information on this, thank you SOO much for explaining this in a way that is understandable and answering EVERY question that we’ve had. Wow, I just can’t express enough how grateful I am for this video lol, I wish we saw this 7 months ago when we first started. Thank god we haven’t had any issues all this time.

Again. very good info and much appreciated. Thanks for taking the time for this excellent video.

This was a great info video, and a eye opener. Not really surprising but a lot of camper owners doesn't even think about this, I've talked to quite a few people with campers and they said they didn't even think about it. So I've told them to check out technorv and watch their videos even the one on tires . I've started getting my rig weighed making changes on the hitch to get the weights more even from axle to axle and the weights in each tire. Big difference on handling when axle weights are closer together.

Thanks very much for a informative article.

Thank you been looking for this exact video

I've always just ran 20 psi under max which is 110 psi on my tires if I'm running light and at 10 psi under max under a load. That way I shouldn't run over max. Never had a problem and I've had tires last for a decade. I also take exceptional care of my tires. I always cover them when not driving. I never use tire "conditioners" like Armorall. That stuff is BAD for tires as it draws moisture out of the rubber causing premature wear. I also religiously inspect my tires for signs of wear and check pressures. I've seen and read too many horror stories about blow outs. I've never put my motorhome on a scale but this year I'm going to as well as installing a TPMS. Great video! I didn't know under inflation is worse than over inflation. Good to know!

Picking this up from the FROG Virtual RV, Thanx for the Video, My first year out pulling my Pop Up I was blowing tires, and I suspect this was due to over loading the trailer. I am much more careful with this now and after the first year, we have a better Idea of what we need to pack and what we don't need to pack. Where I am located I suspect my only option for weighing is the total trailer at an Agriculture shop (single pad). When weighing like this, should I remain connected to the trailer or should I drop the trailer before taking the weight? Thanx.

Fantastic video with very valuable info. Thank you.

Here's how to get the individual weight of each wheel at the CAT scales. Weigh twice. First time weigh each axle on different platforms on the scale. Do a reweigh. Second time I pull the right hand set of tires off the scale onto the shoulder. All of the CAT scales I've seen have at least two feet of shoulder on the right hand side. With the reweigh weight of the left hand side and simple math, you can determine what the weight is of the right hand side. A reweigh only costs $2.00 more.

Great "Info", Thanks a lot, and very well done!

Thanks! I never knew you were supposed to change tire pressure based on weight!!!!

Very helpful, thank you

Excellent info thanks

Great video, but your link to the Continental pressure chart is no good. I tried finding the chart on the Conti site for a VancoFourSeason LT.215/85 R16 with no luck at all.

Great video, the best one i've seen on this specific subject. Still i would appriciate if you could answer one more question. By movement and road angles your vehicle would have dinamic forces acting on the tires. Is there a specific preassure % you need to add depending on the load you're carrying? Or is it already included on the manufacter's chart?

Thank you sir

When I'm traveling in my rv my my fresh water, grey and black tank may be at different capacity, also gas tanks my be full or half full. Am I supposed to keep changing my tire pressures ?

WOW, that is the first time any one has been able to answer the question, is it OK to go over max cold tire psi while driving and the tire heats up and the psi goes %10/15 higher, thank you

The first thing that comes to mind, is the difficulty of finding a location to weight each corner of our coach! I haven't a clue as to where I would go to do that, as the truck scales here just weight 'front axle/rear axle'. Now, on top of this consideration, in reality us RV owners, 'should' be checking our tire pressure before each trip, but again, getting each corner weighed just isn't a common thing, to where getting to a portable scale is an easy option! My coach shows our coach as 12,780 kilograms here in Canada, so doing the math, it's just over 28,000 lbs in it's 36' length, yet the 12,780 is generally useless for calculating each corners air pressure. Going to the tire manufacturers inflation tables, it appears I'm putting in more pressure than I should by 5+ lbs, but we got home a month ago from a 3+ month stay over the winter months to a warmer state, and we had no tire issues, but my tires are now at 6 years old. I do have a TPMS system on our coach, which reads the pressures quite accurately, and I hope someone might have the answer to finding 'portable scales' in all parts of the country, so those with large coaches can get these accurate numbers, for correct pressures! I currently have Michelin XZA3+ 275/80/22.5 tires which to this day have no cracks and basically still look new, so I'm trying to stretch the time period, as Michelin states they should be good up to 10 years?

how about a happy medium psi? I'm sure you are being over technical.

THANKYOU!!!! You answered ALL my questions!!!!!!!

Hello, this was a great video and very helpful! Thank you! Close to where i live, right by a lumber mill, is an unattended Ministry of Transportation self-weigh scale in a large pull out, I assume to accommodate the logging trucks. can i just drive ornto the platform one tire at a time?

great info, thanks.

Ryder and I assume many others overinflate the tires to account for air loss due to lack of driver maintenance. They routinely set all 8 drive tires at 95 psi, which allows the rear axles to carry 40k lbs. Problem is, legally in the USA you can only carry 34. Reducing down to 75 ensures that those tires can carry 34k. Overinflated tires wear faster and of course make the ride worse.

Can you add Big O tire inflation chart?

I have your TPMS and I am satisfied with it. A problem I have is I can't find any two tire pressure gauges that give the same reading, and I can't get nt three gauges and my TPMS to agree. What do you suggest? I have a TireMinder digital gauge and two Jaco analog gauges. Next question; what don't we just air all the tires to the max and get on down the road?

First trip with my TPMS and I used the recommended TP listed on the sticker inside my 35' Georgetown RV which was 92 psi for all six wheels. After an hour of 65 mph travel, I noticed a large difference in the inside/outside dual tires on the right rear. The outside tire only went up to 98 psi while the inside dual went to 112 psi. These are original equipment tires with only 14,500 miles on them. At no time, even at 90 F ambient temperature did any tire exceed 110 degrees F. What would cause such a pressure differential on the same side of the rear axle?

My question is, regarding weight, my Michelin tires are rated at 7160 lbs @ 120psi, but I'm 'well' under 7160 lbs, so should I be below the 120 psi variable, because of the weight of my coach? It seems like I'm 'over-tired' meaning these particular Michelin's are quite possibly made for much heavier coaches that mine, so the previous owner ran 100 Psi front and 110 Psi rear, and I monitor them via the TPMS with pressure & temperature. On a hot day, I've seen as high as 135 degrees, which I suppose isn't that high for a quality tire, but I do keep an eye on the TPMS screen, watching the temps for sure. Still unsure if I should add a little more air, at least to the front, even though I'm below the 'weight' showing on the side of the tire?

I s there a tire chart to compensate for ambient temperature and tire pressure. When I was an airline mechanic we had such charts. We cont have an average 70 degree day to check pressure especially in the southern states or after driving for a few hours. So how do we compensate for the tires actual temperature to get the pressure correct. 15-20 % spreed from cold to high seems awfully high to not get the pressure right.

So, are you telling me I could end up with 4 different tire pressures? (Travel Trailer with 2 axles)

If psi is set by the axle why would individual tire weight matter? If you know axle weight you know what you need to it would seem. 🤔

What did you mean when you said if you haven't been weighed to go with max tire pressure. Are you referring to max cold tire pressure?

Why not just run max cold tire pressure all the time?

Whoa

Manufacturers specs on the door.

Ask 10 different "experts ", get ten different answers.

The manufacturer puts the proper inflation amount on the information sticker. Inflate to that just like you do for your car or truck. Do not just inflate to the max pressure rating of the tire. Your wheels might not be rated for that much pressure and you could loose traction when you need it most.

Too much talk...
