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: https://www.fitmentindustries.com/tire-wheel-backspacing-offset-calculators Fitment galleries for examples: https://www.fitmentindustries.com/search-wheel-offset-gallery

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.

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!

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 👍

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

Appreciate you guys showing us how to figure this out 👌

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

That 86 is so clean love the color

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

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

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

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

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!👍🏽
