These things have been great. they've come off several times and although they're getting a little dinged up don't show it on the wheel, so either way I'd buy another set. I haven't had any strip I don't tighten them over OEM spec for this vehicle 90 lb. It's only a vehicle that has a curb weight of 2700-2800 lbs so I don't know if they'd be more stressed on a heavier vehicle. But for me they are great and great value
