Tom,
Whenever you need to tackle jobs like that, just give me a call. I have an X-12 you can use.
Over-torquing the nuts can crack aluminum wheels around the lug nut holes. In my experience, I’ve never seen a tire shop actually torque the wheels properly. They often put the least experienced person on the heaviest tasks, usually with minimal training.
I buy my tires unmounted, and I handle the demounting, mounting, and torquing myself. It’s less stressful than watching someone damage my aluminum wheels, even though it’s a bit of a workout for me.
I’ve never experienced a shop that torques lug nuts either—until I moved to Texas (hint). In my experience, only one shop, W&W Tire in Boerne, actually torques all lug nuts, whether you’re buying tires or getting them rotated. However, they’re not really a truck tire inventory shop, and their Michelin distributor doesn’t handle the 365.
And Jon is right: overtightening can be a problem. What I meant was that tightening isn’t the roadside task that needs a long cheater bar.
