Figured I’d report back- yes the Mcgard lugnuts I installed are “narrower” @ the base than the stock ones, but the wheels are forged & can take a lot of pressure, if properly torqued to 150 lbs I don’t think there should be an issue there’s still probably like 1/3”-1/2” @ least of contact all around the circumference of the lugnuts & where it sets against the wheel/hole. Plenty of bite.
And for factual proof I drove 350 miles on em over 2 days (chest up cool down cycles + humidity changes from
Being parked overnight outside) - mostly highway but I did drive up over curbs/sidewalks a number of times doing 3 point turns, one time I didn’t mean to & nailed a curb pretty good making wide turn. Also had about 7 miles on rutted crushed stone road where I drove fairly fast & hit some good potholes.
They barely backed out. It’s normal for new lugnuts to back off a bit once first installed & recommended to check again anyhow- these barely backed off just required a hard pull w/ a torque wrench w/ cheater pipe around it &
Only 1/2 needed it.
