Recently had new tires installed at the dealer. Asked the dealer to put all 4 to 42psi. After leaving dealer I check pressures with on board monitor 37,44,39,41. So wait until next morning and set the pressures correctly. I always check my lug nut torques after service. 2 foot 1/2" breaker bar and I thought I was going to snap the studs!! I was pissed already. Next the inevitable, I grab the wheel lock key, line it up and begin to slowly put pressure on the bar. You know what happened, key internals strip. Called dealer, closing at noon, will have to wait until Monday (it was Saturday). So drive around for 2 days with wheels I can't get off my truck, even if I wanted to. Went to dealer Monday and asked them to replace the key or remove the locks and install a new set. They removed and installed a new set on their dime. Parts department was out of lug nuts or I would have bought 4 to replace the locks. So, drive back home, fight all the remaining lug nuts and re-torque to 97ftlbs. Just a warning. I really feel bad for anybody that has to change a flat with severely over tightened lugs. Was hard for me and I was using the 2 foot breaker. Ordering 4 lug nuts as soon as I find a deal going on.
