Does anyone know what the 41' Studebaker Commander lug pattern / tire size is?

Thanks!

Lug pattern for '40-'42 Commander is 5 bolts on 5" diameter bolt circle. Wheels are 16x4.5, so you can use 6.00-16 or 6.50-16 bias ply, or LT215/85 R16 radials (slightly oversize for 4.5" wide rim, but fits). Brake drum is same as all 1/2 ton trucks from '41-'64. Wheels are same p/n as 16" truck wheels for M5. Later truck wheels will fit, but may not have clips for hub caps.

I agree with Gary A., except that I feel that 6.00x16 tires would be too small for a '41 Commander. I would think that 6.50x16 would be a better size.

Now that I'm thinking about it, there are also some 15x6 Stude truck wheels with the same bolt pattern that will fit. There are many more choices in tire size, but none as tall as the 6.50-16 or LT215/85 R16.

Does anyone know of some wider 16" wheels to fit '40-'42 Commanders and Stude 1/2-ton trucks? I think '47-'50 Commanders also use same drum/bolt pattern. Almost anything would be better than the 4.5" wide wheels if you want to use radial tires and keep rpm's down.

isn't 5 on 5" a pretty standard bolt pattern for old hot rods? Also NASCAR for that matter IIRC. should be able to find some custom wheels to fit, if that's your thing.

Re 41 Commanders:

I think stock was 6.25x16 with 6.50 as the option. When Sears was closing their catalog operation several years ago, I bought a set of their 6.50x16's and tubes. They worked fine on the stock wheels and wore out at about 20,000 miles due to misaligned front end.

I have also ran tubeless bias plys on 47 Commander stock wheels. Those wheels are 15 inch x about 6 inches wide, and also work well.

Now I'm running mid-late 60's and early 70's Buick/Cadillac 15 inch wheels with 225x75x15's. Correct bolt pattern and plentiful, however I think they would rub the inside lower edge of stock skirts (wheel disks?)
