I've just installed Nitto nt05 drag radials on my cobra. I only drive on the street and on nice days so they won't see daily abuse. My ? Is how many miles any of you guys have gotten out of them. I'm in PA and we have inspections that I'll need to pass every year. If I need new every year or two it's ok. I get it that it's the price you pay to play but just curious. Thanks for the input.
