I took some pictures to help identify them:

I showed them to my dad who used to be in the tire business, he thought they were 750x20 Stud Piloted.

Looks like the wheels are stamped with a 60130 on the edge.

Stamped on the inside is:

8-51
GOODYEAR
6.00S-20LBW
MAX TIRE 8 25
MADE IN U.S.A.

If they aren't Firestone, then they aren't widowmakers? Should they be replaced anyway?

I found an older post with a link to http://www.accuridewheels.com/completeversion.pdf

But I don't have enough information yet to figure out if one of those wheels will work.

also:

http://www.tireindustry.org/pdf/osha_Rim%20Matching.pdf

But didn't find a match to the information on the wheel.

I read the great http://www.stovebolt.com/techtips/wheels/ but only a fleeting reference to the six bolt pattern my truck has.

Can anybody point me to a guide of how to properly measure the wheels so I know the exact requirements?

Anybody put new rubber on a 6 bolt pattern? What did you do?
