Can over tightening lug nuts warped rotors?

All of the lug nuts have to be tightened gently, finger tight, just a little bit beyond finger tight actually, and then they have to be properly torqued.

How often should lug nuts be replaced?

every 10,000 milesAnd of course wheel nuts should be re-torqued at regular maintenance intervals or every 10,000 miles to account for any changes in clamping force.

Why do my rotors keep getting warped?
