I see several people on here have used the 19" Zeon LTZ tires, and a few of those have moved onto 18" wheels and other things.
Has anyone ever had an offroad failure with the 19" Zeons, particularly a sidewall failure? I hit Colorado trails around once a year or so, and, while I don't go too extreme, almost all trails there have at least one rocky section (if not the whole trail).
I'm still mulling over my options right now. I'm leaning towards sticking with my 19" wheels and getting the Zeons and a full-size spare. The main two 18" wheel options have some drawbacks for me that I won't get into now. Even if I went with the 18" wheel, I'd probably stick with a tire of the same or similar size as stock, so the only advantage would be an E-rated tire and .5" of more rubber between the wheel and the ground.
