18 x 7.5 with a 45mm offset? with a 235/40/18 tire?

 

That is squeezing it pretty tight. No doubt you will have to do some snip and trimming of the bumper tabs. Are you dropped?

 

They will work. I have 18x8's with 235/40/18's. You will need to trim the plastic the rears a little bit. I did not have to roll them. And yes, I am dropped with Eibach's ProKit.

 

What about 225/35/ or 225/45/18 are those any better? I really dont want to do any trimming and i wont be lowering it. If i have to trim, anyone that can help me speak up plz. Thnx

 

I think with 18x7.5, 45 offset, 225/45/18 will work without trimming.

 

What tire do you like better? any others you suggest?

225/45ZR18 91Y Michelin Pilot Sport

225/45YR18 91Y Bridgestone Potenza S-03 Pole Position

225/45ZR18 Continental Sport Contact

22/45ZR18 Pirelli PZero Rosso Asimmetrico

 

225/45YR18 91Y Bridgestone Potenza S-03 Pole Position, but change that to 235/40 18's. With no drop, you will not rub.

 

I suggest following the tire manufacturers recommendations. Since you're on a 7.5" wheel, stay with the 225's. Manufacturers guidelines are there for a reason.
