offset dyslexic

I need to know if the following offset will fit because the website claims it will but im not sure and offsets confuse the heck out of me. Thanks.

Front 18x8 35 offset 235/40/18 tire
Rear 18x9.5 45 offset 255/35/18 tire

Offset is the amount of space that the wheel sits compared to the hub. A smaller offset means the wheel sits farther out from the hub (closer to the fender) whereas the larger it is the closer it sits to the hub (or the brakes for another reference). If you found a 55mm offset that would enable you to run a wider tire whereas a smaller offset would have to run a smaller tire due to the clearance issues.

You are going to be fine.... for the most part. You would much rather have a greater offest. Our cars stock are in the range of 45mm-50mm offest (can't remember what it is exactly). I used to run a 35mm offset wheel on a 245/40/18 tire and needed to roll the fenders to ensure clearance in the front.

My honest advice is to find a wheel with at least a 45mm offset for fronts and backs. My current wheels are 40mm offset in the front and 45mm offset in the back. I run a 245/35/19 in front and 275/35/19 in the backs. Yes I changed to a 19" wheel and I do seldomly rub, but that is also due to my Pedder's xA coilovers (car was lowered due to the springs in the package).

I would say no, but you should be able to go to a size bigger.... 245 in front and 265 (possibly 275) in rear. Only if you stay in the 18" wheel area though. Are you wanting to go rolled or even cut fenders? If so you can easily go with those sizes mentioned and insome tires a size bigger.

When looking at tires, look at the total diameter of the tire. Some tires are a certain size with a certain width as others are bigger in size and the same in width. For example, the Bridgestone Potenzas that I run are known to be "bigger tire" as the overall diameter is the same as that of a smaller width and same size (second number. My 275/40 is equvalent to that of a normal 275/35 of another brand). As long as you look at the overall diamter of the tire you should be fine.

both the posted front and rear offsets are just fine for the tire sizes you posted. You should have no trouble. Front is golden, rear is at the border line of fender rolling, but with the 255 tire, you should be just fine.

Thanks guys, just ordered the wheels and tires. Stuck to the original posted sizes. May go taller on the rear next time. See how these fit first.
