I'm looking at some new tires for my roadster. I would like to put 235/40/18 tires on stock rims on the front. Will they fit without using spacers? My car has not been lowered.
Thanks for the help.

 

Issue is not moving out but contact with the fender liner at full lock. A spacer/larger diameter tire would just make it worse.

 

235/40-18 in the front will fit just fine. You're only adding about 1/3" to the total diameter.

 

Thanks for the reply, but I am also a bit concerned about the tire width and the potential for the wider tire to rub against the upper control arm/ nut. Looks like there is only about 1/2 inch gap with 225/40/18 tires that are now on my car.
thanks.

use the tire calculator at the top of this thread .......

 

Your tire calculator is very helpful. I had not seen that before. Feel better now about buying 235/40/18 tires for the front. Appreciate your help.

I run 235/40-18s on both my N/A and SRT with no problems! Both are @ stock height and rims.

 

I am running 245-35s but I had to use about 1/2 inch spacers but they look great and I have no contact issues.
