I feel like y'all uploaded this specifically for me because I keep checking the website trying to figure out what wheel size I will need

This video was extremely helpful, thanks guys! Here are the sparknotes of the vid for the boys and girls Hopefully it helps Backspacing for your wheels (measurement)- 1:52 Backspacing: is defined as the distance from the hub mounting surface to the inside lip of the wheel (measured in inches). More backspacing puts the tire closer to the center of the vehicle. A related term is known as offset, which relates the hub mounting surface to the centerline of the rim. (2:17) for diagram Compress your strut where you car would be on the ground Get a point of reference (ex. stick) that is long enough to measure (being above your brake rotors) Find the distance of the front mounting hub to the back where the 1st main point of contact of where anything is (ex. strut) - distance between front mounting hub to strut (ex. 8 ⅝ inches) BACKSPACING = 8 ⅝ inches FrontSpacing for your wheels (measurement) - 3:55 Once you figure out back and front spacing, you will know what width you will have to work with FrontSpacing is measured from the inside of the fender to the front of the mounting hub. Get a point of reference (ex. stick) that is long enough to measure (being long enough to go down from your inside fender to the same length as your mounting hub) Find the distance between front of the mounting hub to the inside of the fender (ex. 2 ½ inches) Width (Measurement) - 4:55 (Backspacing + Frontspacing) - 1 inch = Maximum wheel width You round to the nearest inch 8 ⅝ + 2 ½ = 11 ⅛ th inches 11 ⅛ - 1 = 10 ⅛ inches (before rounding) Final Answer: 10 inches Width (maximum) Diameter - 5:58 Use your best judgement for that. Ex. Don’t run a 22 inch wheel on a BRZ or FRS Offset - 6:23 Offset: Offset is the measured distance between the hub mounting surface and the centre line of the rim (in millimeters) (6:39) offset diagram and explanation Positive Offset: the mounting surface is going to move towards the outside of the car (wheel hub is pushed out towards the fenders). AKA means that the wheel is going to sink in more towards the car. Zero Offset: mounting surface is right in the middle Negative Offset: the mounting surface is being pushed towards the the back of the wheel towards the inside of the car while pushing the wheel out. You need to figure out the front spacing to find the backspacing of the wheel Once you find the backspacing of the wheel itself and the width, you can determine your offset Wheel backspacing = Width - Front Spacing Ex. (9:34) - Want to get more of a flush set up w/ a thicker tire Width: We decide to pick a 9.½ inch wheel width (241.3mm) Frontspacing: 2 ½ inches Wheel backspacing = 9.5 - 2.5 Wheel backspacing = 7 inches Results from calculator = 44-45 mm of positive offset Round to the nearest offset mm Offset/Backspacing calculator: www.fitmentindustries.com/tire-wheel-backspacing-offset-calculators Fitment galleries for examples: www.fitmentindustries.com/search-wheel-offset-gallery

This is perfect for first timers trying to learn about wheels and fitment! I've watched about 20 other videos and everyone just talks like everyone was a professional wheel installer. All they had to do was show us step by step examples as this guy did and what they rambled on would make since. Thank to this guy!

Ok. Seriously thank you for this. I spent 4 hours looking how to measure wheels perfectly. And I still didn’t know

Those Enkeis work as a fine OEM+ That's how they should look from factory tbh

When you started drawing on the board i got lost, like on a physics class lol. But you did explained it well, can't get any simpler than that!

THIS FINALLY ANSWERED ALOT OF MY QUESTIONS THANK YOU FITMENT INDUSTRIES!!!!!!!!!!

Man!!! you have no clue how much this actually helps!! Thank you guys so much. keep the awesome vids coming!!👊👊👊

I have been trying to figure out a way to calculate the perfect offset for my car. Thank you Gels and Fitment Industries for the valuable information.

Reminds me of my math teacher 👨‍🏫 still don’t get it 😴🤣

This is the most helpful video that I’ve seen so far Thanks so much for posting this

You guys do a great job. Keep up the great content! I love this channel!

Videos saved; Will be watching this video a few times to make sure I fully understand; wouldn’t want to pay any restocking fees 😅

FRS cleeeaaan ASF nice fitment !

Boom, Bop, Bang, now you're ready for your Nankangs.

Offset explanation is really good, thank you. I finally get it. Also great guide on measurements.

extremely new to this, i just bought a 97 ls 400 this past friday and i gotta say if learned more in this video than probably ten previous videos from other channels

Hells Yeah!! This helps a lot! Useful information I was looking for. Thanks guys.... Keep up the good work 👍

Can’t lie I was always scared to get wheels with all the math involved started following you guys now it’s no big deal plus the gallery really is a lifesaver to know what you’ll see on your car

Thanks for the video. This information is very important to know which rin to buy correctly!

Thank you. Been looking for a video like this for my simple minded brain. Very helpful

Appreciate you guys showing us how to figure this out 👌

That 86 is so clean love the color

Damn most helpful video I've seen to help me choose the right wheels for the fitment I want.huge 👍

Answered everything my brother and I were looking for and the calculator helps alot thanks👍

Just the video I needed! Before getting enkei Vortex5 wheels

Thanks for breaking this down for a simpleton like myself I actually just learned a whole lot.

i need this video like yesterday. thanks

Feel like this video was directed at me lol. Shoutout Christian and Beck for being SUPER patient with me. I'll be ordering my set up real soon. Lmfao.

Thanks a lot my brother, this wheel off set explanation is clear as the water. I’m planning to get some wheels and this is very helpful! Thanks again!👍🏽

Very helpful video. Thanks 🤙🏽

Yes an info vid that’s useful! 🙏 thank you!

Great vid very helpful! 👌🏻👌🏻

Bin waiting a long time for this video guys thank you 🤓🤓📚📚 A+++

Fantastic! This is exactly what I want!

This video is so useful thank you sooo muchhh

I was literally just wondering how to do this and this helped vastly

This is extremely helpful because I’ll be looking to get some aftermarket wheels pretty soon for my Benz

Absolutely awesome thank you

Thank god for this video 😭finally after months of trying to figure out what my future wheel fitment was going to be I did it thanks to you guys

Just simple and great video so thanks alot! going to get some wheels to Volvo 240 and hope to get the fitment what i'm after :)

See, im the idiot who buys the wheels i want then modifys the whole car to make them fit 🤦🏼‍♀️ which ends up costing 5x as much

Well explained. Thanks.

thanks!!!!!!!!! I needed that video

Good vid, I was looking into some new Enkei wheels for my G.

This helped me a lot.

this production quality is INSANE

Perfect! I have orange FRS too, but its all Toyota badges now.

This is just such a knowledgeable video. Everything you guys do is for the better. Love it guys. Keep up the good work. Anyway you guys can add the background music in the description box for future videos?? I particularly like the song in this one but couldn’t find it. 😅

And now I get it. Thanks guys

This video should have hundreds of thousands of views.

I'll need to watch this one again 😵

very helpful!! thank god for a business such as FI.

YES! this is the video I was looking for to see if I can run the rims I want on my camry. This should be the first video everyone watches before buying any rims.

Amazing Video. Very well Educated 👍

This has to be the most underratted channel on KZfaq

You guys are true Goats

I’ve been waiting for this video😅 I’m thinking about wide bodying a Lexus is300 but idk what sizes to get. I know the back wheels are supposed to be wider but I’m new to this😅

Thank you

Just bought some wheels from Fitment. Let's hope they get here nice a safe. Look for my car in the gallery once she's all done. It's a Black 86 with bronze konig 17x8 freeforms. Coilovers also.

Finally a video that help the noob like me to find the correct fitment. Cuzz im like huh all these number lol. But thank you for going into detail !!!

u a good teacher

Technical Gure at work❤

@fitmentindustries you guys just slapped me with god like Knowledge

Fitment industries is so much cooler considering the fact that they are based in Wisconsin. I don't live there anymore but it just makes it even more fun to support them.

I see you there you ol’ lefty you #southpaw Also please make this into a thing. I learnt so much and now I want more

That's a lot of technical info but if I understand correctly, I can run a 22"x14" on my NA Miata. Thanks, FI!

This was super helpful! I have one question and I hope you can clear this up. Still unsure how to determine the maximum negative offset based the backspacing. Could you technically go as low as a +20 offset with your current setup on your FRS? Would a thinner wheel allow you to go even lower?

But I'm going to tell you what I LOVE about fitment industries, How fast they ship is NO JOKE, and they update you in the process. Outcasts garage needs to take notes from fitment industries.

Bro, I have a 99 GS300 and plan on going aggressive, And I have to say you couldn’t of made this any easier to figure out. This is nothing like my Yukon where I lift it 9 inches and throw some 24x 14’s with 40s on it and call it a day with minor trimming 😂😂 this shit is technical. Thanks again!

I wish I had this video to look at when getting wheels for my car as mine is pretty rare. Fortunately my trial and error ended with 0 errors.

very helpful video, thank you. Unfortunately being in the UK the FI gallery does not have my make and model car.

if i heard correctly, are yall using Andre 3000's aquemini beat in the background? If yall are that made stuff seem so chill in the video lol

These are well explained but i was wondering if someone already came up with an autocad 2d visual of the wheel plus suspension and well where you can play around with the numbers and get the look at the same time

Finished the video, and I’m sitting here thinking, “it’s probably a good time to tell y’all I barely passed math back in high school”😂😂😂😂😂

excellent video right here! this will give me a peace of mind knowing what wheel specs i will begetting. this is much much appreciated. here is my question: my suspesion is old and most probably worn out. planning on getting a bc racing br for a daily 2005 4dr 325i. should i measure now or should i wait until the coilovers are installed and then measure? thanks!

oh and Gels, your car is hella clean

Dude, I feel like am back in math class. I got sleepy😂 I still like the video because I need to know this stuff

once the wheel is off do you just raise the brake rotor as far up as it would go? Im not sure how high the car usually sits. On stock suspension

I have a 2015 Honda Accord looking for the right type I keep hearing about chrome lip silver any help I was thinking about eBay your thoughts

This was frkingggg good top math shitz

finally!!! I understand.fac

will the backspacing be the same in the front and rear??

For your 9.5" wheel in the example shouldn't you have been using the full width dimension of 10.5" when calculating front space to take into account the outer edge that would actually come in contact with the fender?

Is it bad to find your wheels based on offset? For example, if I want a deep lip rim, is it bad to search for rims with a very low offset and then try to match up the rest of the dimensions?

When final offset is found with the backspacing of the weel(7inch)..Does it mean that your setup will be conservative,or flush,etc...?

So I'm a little lost around offset, so if your offset was 44, how much of a breathing room do you have to go lower or higher?

I’m just gonna use the website lol. A lot easier. Anyway I’m not going for any stance figment anyways. Just going for a good track setup.

Patrick write that down write that down!!!

I wish I could like this video twice

Me coming to this video after selling my 8j et35 wheels that needed 5mm spacers, and now i got 8j with 60 offset and they hit the calipers even with 10mm spacers Mathematically I'd need 25-30mm spacers to be a perfect fitment, realistically I'd have no idea without this video because im going for the drippy fitment Ps: i have an opel astra bertone on coilovers

So now how does the tire size especially sidewall height factor in?

Looking forward to getting some Red Opal Hypergrams...if they're ever off back order :v

How do I know if the rim that i would like to get is gonna clear with the caliper? 🤔

Should of teached us fitment class in high school

what coils are you running

is there anyway possible that I can fit a 215/45/R17 tire on a 18x7.5 wheel?

how about measuring the caliper clearance especially if you have a bbk.

Great video! 👍 Give it time though... I guar-an-tee there will be owners who run 20"s on BRZ/FRS/86s 🙄... and then there will be owners who run 14"s 😒
