I have a set of 225/45/15 rival-S on the car now and they grip well and fit pretty well. my other set is a 205/50/15 hoosier A6 for track both are on 15x8 rims and the 205's fit the 8 inch rim prerfect from a square tire look and the 225 have just a little bulge but are very nice looking for me it came down to size of 225/45 and I could only find BFG and Hankooks rs3-Vs so I went BFG for max grip and from what I am told the RE71 and the Rival-S are bout the same in the dry and the wet but both will wear faster than the tire they replaced (not a worry for me I needed traction with the 375whp the GTX provided)
