When changing tires, on a front wheel drive vehicle with alloy rims, the parking break on, and entire front or back end lifted: after hand tightening the nuts, can they be torqued to spec off the ground, then re-torqued after lowering?
Or should they only be tightened partially off the ground, and torqued once after lowering? Assume the appropriate tightening pattern is being used in either case.
I've seen various takes on this, with some suggesting torqueing off the ground is a problem or risk, but I've never seen a good explanation why (except from people who don't seem to have the parking break on so the tire spins on them).
I'm looking for specific details on why one or both of these methods may or may not be safe/ok to use.
