I can't seem to find the right tire for the Viper. Should be pushing a bit north of 600whp. I was originally going to go with 345/35/18 MT ET Street II's but I think that's too much tire and not enough longevity to be honest. I drive probably 8000 miles in a year with the Viper so I wanna find a nice radial that could at least last 1 season of abuse. I'm thinking of the Nitto NT555R but the only size close to what I need is 335/30/18. Nitto states the overall width of the tire is 13.19" but says the max width to be used on is 12.5". Could I get away with being a 1/2" too big? Or should I keep looking for another radial?
