Stud Size and Wheel Torque

[tropical36]

What do you suppose the stud size is for my wheels....9/16 or 5/8??...
I have 5 on the front wheels and 10 on the duals...I also have a tag axle...so with the ring mount, what do you suppose the wheel torque is for each set?...
This is a 97 chev. P32 chassis with a 98 36ft. National MotorHome on top...
I assume this to be the same as a 99 or 2000 Workhorse...

DPG 4815,

Can't tell you about your P-32, but I'm sure they are metric, not SAE. I had to buy a 22MM 1.5, tap and dye to redo some studs and lug nuts on my W-22 rig. GM went to metric long before your rig was built, sometime around '78 or '79. The Chevrolet folks could give you the specific info you need--
Good luck,

Max

Thanks...and I finally did get the info that I needed...the workhorse online manual explains it best...and my 98 chevy is the same as their 99...I'm also including the info on the W series..

The P Series 12,300 lb. chassis have 8 hole wheels with 9/16"� wheels studs, 1"� lug nut and require 140 lb. ft. torque. These wheels have a 2,440 lb. wheel capacity. The 14,800 lb., 15,000 lbs, 1 6,500 lb., 1 7,000 lb., and I 8,000 lb. chassis have I 0 hole wheels with 5/8"� studs, I " lug nut and requires 175 lb. ft. torque. Both front and rear wheels hthre a 10 hole bolt pattern for proper tire rotation, although the front axle only utilizes 5 holes and the rear all 10 holes. This is due to the differences in carrying capacity, single compared to dual wheels, and the rear axle is the driving axle. Prior to the wide track suspension the wheels had a 2,760 lb. wheel capacity. All wide track suspension, which begin in 2000 model year, and the 14,800 lb. chassis starting on 1/21/02 have a 3,000 lb. capacity."


"The W Series 16,000 lb. and 18,000 lb. GVWR chassis have an 10 hole wheel with 5/8"� wheel studs, 27mm lug nut and requires 150 lb. ft. torque. These wheels have a 3750 lb capacity. The w Series 20,700 lb., 22,000 lb. and 24,000 lb. GVWR chassis have an 8 hole wheel with 22mm wheel studs, 33mm lug nut and requires 475 lb. ft. torque. These wheels have a 5000 lb capacity. All W Series wheels are a hub centering style wheel.
