I ran 275/35 on my 17x8 bullit wheels and they looked and worked great. Now I havea 295/45 on 18x10 on the back of my car with the 275 on 17s on the front. works good for me. Although the back is a little to tall for me on my car. I have a 96 gt.

 

275-40 will fit and are equal to the stock tire height so your speedo wont be fugged[8D]
