Before our last run, I went to a local shell gas station to fill up. I heard a weird sound and pulled over to find a shiner in my mud terrains. It turned out to be a bolt which someone cut down than put through a grinder to give it a needle point which went through the fat part of my tire. I of course have a new spare but the tread is thicker and I had the hole plugged in the old tire.
My big question is it safe to air down now or should I replace my tires which are getting low but have a few thousand miles left on them?
