I recently put new wheels on my car. I don't have off-street parking, much less a garage to work in, so I had the wheels installed by a mechanic. Since they were installed, they have been driven through about 100 miles, including an autocross event, so I think it's about time to check the lug nut torque.
I refuse to take it to a mechanic just for this, so I'll do it myself. I've got a torque wrench and appropriate sockets, but I'm not sure whether the weight of the car affects the torque I'd see on the lugs. Do I need to lift the car up to take the weight off the wheels while I check the torque?
