Yes, you can fit 235/40 on those 8" wide wheels.

GregL · 08-10-2009, 05:55 PM

Sure, a 235/40/18 tire supports rims from 8-9.5" wide. Plus many of us run 235/35/19 tires on the front.

But I just looked up the Crono and unless I'm mistaken, it'll be horribly sunken in between an 8" wide rim and 40mm offset.

225 or 235 works perfectly fine on a 8" wheel. 235's will give off a more full look on a 8" wheel.

True, but they are ET34 not 40 so maybe not too bad?

Do you guys think that going to 19lb rims and 25lb tires is going to give the car a palpable feel in acceleration vs stock 26lb rims and 32 lbs tires. Difference of 14lbs a corner.

+1...that's a difference of 14 lbs of unsprung weight at each corner which means 140 lbs of sprung weight at each corner (1 lb of unsprung = 10 lbs of sprung). She'll be noticeably quicker!

Go for the ET34. That will be much better fit than ET40. I am running ET32 on my car with 235/40/18 - This also works well.

On what rims?

John_01 · 08-10-2009, 08:51 PM

My rims are Advan RS 18x8.5 ET32 on all corners. Looks like this. I think the OZ Chrono looks good for the price, but it would be good to see them fitted. In some ways an 8" wide rim is better for 235 tires because the rim won't be as exposed as mine are.
