I'm running Enkei EKM3 wheels, 18"x7.5" with an offset of 45mm and dropped on Eibach springs. Looking at replacing the tires this spring with Hankook Ventus V12s, can i run a 235/40 tire without rubbing issues or should I stick with a 225/40"?
 
I'm running 235/40 with 18x7.5 +48 offset stock height. I rub ever so slightly when the car is loaded with 800 lbs worth of humans over bumps.
 
225 you won't have to roll the rear, 235 roll it and call it a day.
Yup, pretty much. I'd go with the 235/40's since it'll be nice and squared/tad chunky with the wheel, won't give you as much wheel gap as 225/40's would and riide will be nicer too.
 
I ended up ordering the 225/40 sized tires today, just don't want to have to get the fenders rolled. Thanks everyone for the helpful advice!
 
if youre lowered, id probably go 225 myself. but i'm gonna go 235's on my 7.5's on stock suspension. has anyone had bad experiences with rolling fenders?
 
the stock size is 215/45 ? the plus one is 225/40. The 235 is stretching it on a 7.5 imho. I bought wider wheels and put 225/40 but also worried about the rear fender as my car gets a little lower with different springs. I am going to consider 235 in front for the 1/4 mile though when i replace the fronts again. Also to the op, the narrower shorter tire often weighs less, you have some light wheels already and maybe you can gain traction with a softer tire without getting big. I think its rotational mass theory or something they say is important to go faster.
But maybe you are going for the wheel gap. Probably gotta roll the rears then
 
215/45 is 235/40 in overall height. 225/40 is too short. Just as 255/35 would be +2. If that were a size
 
235 on 7.5 and rolled the rear fender cost me $40 and I am happy. This tire size is more abundant.
