So my birthday is coming up and my g/f is being a sweetheart and is going to go half on rims for me. I have my mind made up on the ZR-1s, Summit and Jegs sells them, they are made by Detroit Wheels. I plan on the 17x9.5 for up front. However, for the back, I am undecided. Should I run 17x9.5 P275 Nitto Drag Radials or 17x11 with P315 Nitto Drag Radials. I know some people have had fitment issues with 17x11s and others have not after doing a search of previous posts.Will there be a huge traction difference between the P275 tire and the P315? Either way I am going to run DRs. Thank you for any input.
