So I was in my local shop looking to get another set of ITP rims with some RZR II's, and I can't believe the price jump from when I purchased them before. They have doubled in the year that I have had them. Now I think they are an amazing tire, and the only reason I am wanting more is because I had mine all studded up, and with the few plugs I am going to need to put in them, I just want some other ones for more summer races, along with the fact that the rims on there now are a little bit thrashed. Anyway, the guy at my local Honda shop pointed out these GBC XREX tires, that have the same pattern as the RZR II's, for half the price, and they are 6-ply as well. Has anyone used these at all? I am curious before I sink $500 in a new thing of rims and tires.
