I changed my rear wheels every week for a year now (switching to drag radials) torque them without a torque wrench ,, have been doing this for a year on the Xfire, and 55 years on other cars, have i ever striped and maybe can't remember but have broken a few.never broken or striped any in a year now, I installed my wheels and had a tire shop check them for torque each one was different 1= 81' lbs 2=79'lbs 3=85'lbs 4 =90' lbs and last one was 83'lbs,, i only checked one wheel the guys at the shop ask how i did that, i mounted the wheel in front of them, when i said "you don't need to check the torque they wanted to anyway .. jim
