[Tigers] Road Wheel Nut Torque

	It all depends on the material of the bolt and how it was made.
Generally a grade 8, 7/16 bolt can be torqued to 78 ft lbs.

I'm not sure what grade bolt the wheel studs are.

Hi All, anyone know if the stock 7/16 wheel studs can safely take the lug
nuts being torqued to more than the 48 lbs. ft specified in the shop manual
if one is now using aftermarket wheels and lug nuts? Torque charts today say
to go to 70-80 ft. pounds on 7/16 studs. Maybe the 48 lbs. ft. stock figure
is due to limits imposed by strength of the OEM nut or wheel rather than
stud strength? Cheers, Gene
