I'm trying to catch up. Third set of tires on the Super Stock in 6,000 miles, went through 2 sets of NT05Rs currently running Nitto G2s all around.
I also change out all my vehicles tires and wheels every season. Truck has summer (Nitto NV420s) and winter (Bridgestone Blizzaks) tires as well as the wife's Cherokee (Michilins, Blizzaks). The Wrangler has on road (Nexus) and off road (Goodyear Wrangler Ultraterrain AT) sets as well as a winter set (Blizzaks) the only thing that doesn't have multiple sets is the Road Glide
I have a garage at my property that seems all I do is store sets of tires in it. I have Discount tire change them out on all the vehicles except the SS. They balance, rotate and torque them each season for no charge since I buy them all through them.
