The choices for even the stock GNX tire sizes really suck. According to tirerack.com, only a few make even a 255/50/16, and those that do don't make a 245. I don't want 2 different make tires. That is stupid. Why are 16" rims so difficult to fit? I can't find bigger than 255, I'd like lower profile than 50, but that can't be found either.
