Im looking at msr 045 style wheels in a 18 i know alot of people are running thes rims, what size tire do i need to run?

 

225/40/18 will work just fine.

 

235/40/18 would be better. 225's are stretched a bit on an 8" wide wheel. More traction ftw also!

 

Any clearance issuse with the 235 im lowered on eibach pro kit!!!!

 

The height difference is only .39 so I doubt you will rub. The pro kit doesnt lower the ss at all right?

 

Well mine aint an ss its just an lt model.

 

If you have an LT, just get 225/40/18's to keep the diameter down. You have no need for the added traction of 235's anyway.

 

Well i like the looks of the wide tire tho! But when you think about it is it going to kill my power!

 

235/40/18's will be a substantial jump in diameter over your stock tires. That would kill a bit of your low end acceleration and throw your speedometer off a bit. I would stick with 225/40's. They will look fine and keep the diameter down by about .4".
