Hello everyone! New to the ATHS forum.


I am trying to identify the wheel type on a truck I purchased. I purchased a 1977 International Loadstar 1850 about 600 miles from home. I plan to drive it home so I want to put some good used wheels and tires on it for the drive home. It currently has 10 lug 20" wheels and 9.00x20 or 10.00x20 tires on it now. I plan to purchase a good set of 11R22.5 tires and 22.5 wheels from a truck salvage yard not far from the truck for the drive home. Or possibly borrow a set of hub pilot wheels from a friend if that is what fits my truck.


I was assuming stud pilot wheels were the standard in the late 70s and was what this truck would have. I thought hub pilot was more 90s and newer. I have not yet seen the truck in person and when I looked closely at the pictures it appears to me the lug nuts look like the nuts for hub pilot wheels without the budd. I also see a raised part in the hub casting that might be for centering the wheel.


Could someone else give me their opinion if these are stud pilot budd wheels or hub pilot wheels?

They look STUD piloted to me with the flare on the nut to fit into the bevel tapered part of the wheel. If you can get a picture of the rear wheel and the stud has a square end it is definitely STUD piloted.When changing the rear wheels, that is a 3 piece stud.. The outer nut holds on the outer wheel then the square headed stud holds on the inner wheel threaded to a stud sticking out of the brake drum.. If the square headed stud breaks you then have to use a pipe wrench and cheater pipe to get it off.. If the square headed stud come off with the outer wheel you then have to hold the outer nut with a socket and turn the square headed stud thru the nut..
Are you totally confused yet???????? Also look out for left handed threads on the drivers side.. Should be an "L" stamped into the stud???
Be sure to use plenty of rust blaster and let it set for a while before trying to take the wheels off.

Thanks for the reply Brocky! Makes a lot of sense. I think I have seen that type of lug setup before.
I will contact the guy and see if he can text me a picture of the rear wheel, that should clear up a lot.


Thankfully the truck salvage place only wants $60 each for steel 22.5 budd wheels. They have a set of nice low mile used 11R22.5 Firestones for $350 each. Seemed steep at first since I can get cheap tires for $300 each new, but the quality difference might be worth it.
