Budd/ hub pilot mixup

Do not mix those two mounting systems and work them. They will come loose and fail. The new hub pilot system is hard to keep tight already and doesn’t need anymore help caused by a mismatch. Wheel-offs with the new system are a real thing.
If it is a ultra low mileage hobby truck that has no chance of seeing high torque and high load to the rears then maybe ok. But I’d be checking them regularly and the only way i’d personally do it is if they were some rare wheel like the old 5 hole Alcoa’s or something like that. If they are just standard everyday 10 hole or steel wheels just Sell or Trade the stud pilots for the right hub pilot wheels. That way you have the piece of mind that they will not fall off.

 

It can technically work as you seen. Later versions of ball and seat wheels used the 11.25" pattern and 8.72" center hole the same as hub piloted wheels. So the wheel centers up and rests on hub just like a hub piloted wheels. Your not supposed to do it, but it does work.

 

But it won’t work at all, the other way around. Aren’t the hub centers different diameters?

 

Same measurements on bore 8.72"=220MM, bolt circle is same @ 11.25"=285.75MM. Alcoa is the same way. Sure it's cheaper to set die for forge for one bore size. Aftermarket pickup wheels are the same way.

 

Thanks for the input everyone
Wore out I was not trying to go against your advice just more stating other things I have observed. I do value your knowledge and I hate to admit this but your correct that I had already decided what to do and it wasn’t what you assumed. I just wanted someone to tell me that they had done what I saw and it worked great or it failed miserably.
I had hp rims on hand but was more thinking about finishing the tires rather than dismount and remount mostly because it’s a busy time for dump trucks. It rained this morning and everything is honkeydorry the Budd rims are in the junk pile and the truck has all hp rims on it.

 

Currently, but I know some of the old budd wheels had rough punched center holes that were probably 11 5/16 or whatever they got when they punched them
I bet this is what milemarker is thinking of based on his latest post

 

I have seen a guy machine spacers to put in the budds to make them "truer" hub-piloted wheels.

 

Gotcha. Thought you were mentioning the hub, and thought the moving wheel may have made the marks mentioned. Glad you got em swapped

 

Seems like a awful alot of work.
