I have a quick tire question. Will going from the stock tire size of 235/45/17 to 255/40/17 increase the fender to wheel gap, or reduce it? I have tein s-tech springs currently on the car. And also, will there be less ground clearance, and will the new tire rub at all from the increased width. Thanks, Sean

 

235/45/17 od is 25.3 and 255/40/17 od is 25.03.......http://www.1010tires.com/TireSizeCalculator.asp

 

so there would be a bigger gap between the fender and tire with the 255's? would 255's with a 45 sidewall fit in the evo without any problems?

 

no, its only three tenths of an inch difference in height. you'll never notice/see that little change in height.
