I have a set of Goodyear Wrangler Authority AT in 31x10.5 with about 500 miles on them. The just came off of the 40. Selling the wheels too.My 40 is (over)due for new tires. One won't even hold air for more than a couple of days. Thinking about going the super-cheap route with GY Wrangler Trailrunner AT in 235/75-15. They're under $130 per with $80 rebate. So that should be under 7 bills for all five. I'd love to go BFG or Toyo, but finding it hard to justify it on a truck that gets driven a few times a year.
