I can get my hands on some GSR Blades for 400, and 500 for rims and tires, but the tires only have 50% tread left... what I was thinking is that I could look at the tires and decide, but if I don't like the tires what size tire should I run with these 15" GSR Blades. Here are some pics of the rims below, they are polished, but they probably need to be re-done, but my buddy can do them for cheap. Input please. They will be going on a black EJ Coupe.
