I am looking at getting some new rims this summer, I did a search and still have a few questions, here we go:
I am going to get 18 x 9.5 rims for all four corners
to run 255 or 265 / 40 or 35 / 18 TIRES
I know the Bolt pattern is 5x4.75 (120.65 mm)
1) What offset do I need?
2) What back spacing do I need?

I don't want to do any modification to the fenders, don't want the wheels to rub or stick out and I would like to get a sort of deep dish look, but the wheels fitting as stock. I just want to bolt the wheels on and go.

It is my daily driver ( 6 miles daily M-F only), i will be putting the Wings West custom kit and in the future possibly doing the Ibach pro kit.

***I don't know if it would be possible, but it'S worth a shot***

ANY INPUT WILL BE GREATLY APPRECIATED, THANKS IN ADVANCE...

 

9.5 inch wheels should get at least a 275. I'd even go 285 if I had a few extra bucks.

 

I'm looking at the Smothies II, do those come in 9.5 or 9'' in width? i also kinda wanted to get some Chrome wheels....

 

My buddy, Ford, just purchased some 18x9 Smoothie II's. Some places listed them as 9s, some as 9.5s, much like the ZR1 wheel.

He easily fit a 275 on there, and wants to go with 295s for the rear.
