Can you help me out with rim size and bolt pattern for a 1946 gmc 1/2 ton . Probably Canadian made if that matters . Thanks

Nissan, Toyota, Isuzu, Mitsubishi, Land Cruiser, etc. and all their American-badged clones like Dodge Ram 50, Ford Courier, Chevy LUV, etc. have the 6-lug wheels. Most of them are 15", but just to roll it up on a trailer you don't need an exact match.

You're looking for 6 holes on a 5 1/2" bolt circle. I recently removed the tires from my stock rims for sandblasting otherwise I could have loaned you one.

I am now using old Japanese vehicle wheels described by Jerry. They work fine on the rear but provide limited steering-movement on the front (offset problems). As Jerry posted, they work fine for straight forward/backward rolling (and, wide turning).

I would also love to see some pictures one you get it home. I'm building a Canadian built 46 GMC 3/4 ton currently.

If you put some washers over the studs and found some extended lug nuts you might get a modern wheel to snug up enough for rolling it around.
