After fender modifications you can easily fit 20's. Dont listen to all these guys pushin 18's and 19's.

again it all depends on your tire size and offset.

and yes the red IS does have some wheel gap up front. the rear looks pretty good though.

Wheel/tire gurus feel free to correct me if I'm wrong, but if you adjust your tire sizes for the 20's, then your wheels should fit NO different than a comparable width/offset of a 17/18/19" rim.

To best keep with stock 18" tire sizes, you need a 225/30/20 front and a 255/30/20 rear [assuming you can handle 30 series tires ]

So, get those sizes and then do a width/offset that you know works.

Also, doing this will keep you from having the 4x4 look, as the overall diameter will be almost the same as stock.



Check out 1010tires.com for more offset and tire size calculators.

if your overall rolling diameter is the same, your car will still look like its "lifted" even though the overall diameter is the same. thats the illusion you get when you have a bigger wheel and smaller tire.

even if you adjust your tire size correctly, you can still run into issues with the width and offset of the wheel. if your stock wheel is 7" wide and your new wheel is 8.5" wide, you can calc the offset to get the wheel to sit the same inward from the wheel well as a stock wheel (its kind of hard to explain) but you still have a wider rim which is whats going to give you a problem.

Yes or a simple way to look at it:

With the larger diameter wheel the tire sidewall height is reduced. So the fender gap ends up looking bigger versus the short sidewall of the lower profile tire.

For the front get a heat gun and push the fender liner back where the tire is rubbing. Depending how wide of a back tire you choose you will need to cut/or roll the back fenders. Its easy and after all this I can still lower it, just havent.
