Good point Clifford but yeah buses don't get that kind of abuse. I have run 10" spread axles trailes 40,000 pounds on them they really catch hell on turns loaded if you forget to dump air on turns.

Yea they break I bought Alcoa's by the pallet.there was always enough in the scrap pile to have a nice BBQ every 6 months. I never had many studs to break. Kim would see one the threads showed a lot wear he would replace it, buses don't have many flats compared to truck in and out of jobs sites probably a 50 to 1 ratio between the 2.There was torque wrench on the board., Kim used a preset impact I/R gun with regulator no one was allowed to touch lol he always checked one and would use the impact and was never was off over 2 to 5 lbs when I made him check a few for me.Now the tire shops were a different game

There is a 2 piece "go-no go" gauge for aluminum rims and cap nuts.

If the first piece inserted through the seat, pokes out beyond the second piece place on the other side, the seats are worn beyond tolerances.

I would not purchase a used wheel without one of those to check it first.

happy coaching!

Rule of thumb if the hex on the nut is hitting on the wheel and no sign of seeing the bevel on the nut with the Alcoa nut the wheel is gone the cone bevel is too deep

Maybe torsilastic suspension puts more shock on wheels and studs when wheels are angled. Anyway , there was a major scandal several years ago concerning junk fasteners. Resulted, among other things, all fasteners had to be stamped or marked to indicate mfgr., so failures could be traced.
In his case, worn out, fatigued fasteners from how many tightening and overtightening events from 40 plus years.

There is still some junk out there  ,I bought a set of Dorman studs that were made in China and were so junky I sent them back, stay with Euclid/Meritor they cost more but a lot better quality.Amazing the price people gouge you for now for stud pilot wheels you can buy hub pilot studs M22 all day long for 5 bucks each made in the USA grade 12.The stud pilot system is going away fast, I bought  2 sets of longer stud pilot studs from Luke for Kays MCI friggn 700 bucks with out the nuts.Luke had the studs I could have saved money buying from Prevost but they were out of stock and couldn't give me a date when they would have stock,  then Alcoa charged me $ 4.00 each for nuts X'20 prices are stupid
