Wide tires, what offset?
Planning on buying zo6 repo wheels
Size 17x9.5 front
18x10.5 Rear
Very interested in using the Nitto 555dr tire for the rear which is a 305/40/18. What offset should the wheels be to make these tires fit and not pop out of the rear fender? Would a 56mm offset front wheel and back wheel be ok? Can it be done with out a tub? I want a clean look, but want that fat tire back there. I have searched but have not come up with a definate answer.
Thank you for your help and time.

Forgot to mention the car is a 2000 coupe. I am also thinking of putting 275/45/17 in the front. Do you think that size of a tire is too large for the front? I am looking for all around performance, but this is my daily driver.
Thank you.
Thank you.

I had 18 x 10.5's, thin spoke repo's on with 315's and they stuck out less than a qtr inch, looked flush unless you got close and took a good look. I am not sure of the offsets on the wheels though, the wheels were from Bob's. I would say 305's would be flush or very close to flush, 295's are just inside of flush with the wheel well.
I ran 285's on the front on 18 inch rims and they fit nice.

Where did you see a 305/40/18? They make 305/35 or 305/45, not a 40 series 
Also have heard 255/45 is pushing it for the front, no way 275/45, you gotta get a smaller sidewall ratio when you go wider.

Where have heard about the fronts being too big? I have heard many people go up to a 275 or even a 285 front tire. Isn't the oem zo6 front tires 265? Are you saying I could go wider, but I would need to consider like a 40 or 35 series?
Thank you so much for help.

305/45 will not work either, you will rub, even if you had stock height.
Saw about the fronts in a post a day or so ago, and yes many go to 275 or even wider, but must go with smaller sidewall like 40/35
Check out this site: Tire Calculator It will help you see why these tires you are trying to use will not work and hopefully get you some that will. I know tires are a major PITA sometimes, I am going through it too.

Thank you very much for your help. I will use that tire size calculator to figure out what I can do. I guess I just dont want to buy some repo wheels and then find out I bought the wrong wheel size for the size of tires I want. What a PITA.
