Are you only considering the F1 or the Nitto’s? It seems there are few options. Here are a couple more threads on Avon tires, Toyo Proxies, and somewhere the SRT Experience gang is using Michelins.
I personally will stick with the F1's.....after all if DanRealtor is on his 5th set of them they can't be all that bad.
