I got a set of ZO6 wheels for my 91Z and would like to run 245/45/17 on the front 17x9.5 wheel with 2" spacers and 285/35/18 on the rear 18x10.5 wheel with 2.25" spacers. I've searched this site and haven't found that exact combo. Has anyone ran those sizes and if so how did it work out for ya?

Post pics when you get them on because I was thinking of doing the same.

Is there a reason you plan on running 245/45-17 on the front on a 9.5" wide rim? I am running 285/35-18 on the rear, but up front I have 18x8s with 245/40-18.

The 285/35-18 fit no problem. I am personally thinking about stepping up to a 305 with a bigger sidewall. Your front fitment is small also. I think I have 265s/30 R18. I did not have to do any trimming. I have cut down moog springs and valved Bilstiens. I do a fair bit of autocrossing and road coursing. I have had no problems. I am actually thinking of getting it lower.

I plan on it, but putting it back together from the paint shop at the moment.


The reason I'm going with 17's up front is cause I got a set of stock ZO6 wheels and that is the size, 17x9.5 up front and 18x10.5 in the rear. So I'm trying to get the best size tires on the first try.


I now think I am going to go with 295/35 R18 in the back and still uncertain on the front. I'm trying to get the overall tire diameter close to my current set up and this link has a tire calculator that has helped. http://www.rimsntires.com/specs.jsp?item=Wheel-Tire

When I had my z06 wheels, I ran 275/40-17 up front, and 295/35-18 in the rear.

Wow a 275 up front. Any issues with rubbing and what size spacers/adapters were you running? If you happen to have any pictures of them mounted, could you post them up?

thats the way to go.
