Old six lug pattern 20 inch

[gabbagabbahey]

Is there such a thing?
Would like to find 20 inch wheels that use the old 6 lug (8.125 ?) Bolt pattern, but donno if such a thing exist.
Thanks, john

Never seen them, but made my own out of 20" 10 lug GM wheels that had the same lug circle dia. Installed on 62 W300.

Details? Were the centers cut out and news' welded in?
Wanting to jump start my W300 project that stalled years ago due to a lack of 6 lug adapters/spacers for the duels. Saw some 8.25×20 powerkings today and thought that my be the ticket.

The rims came off of old 50's buses. 10 holes on same circle meant 2 holes lined up perfectly. Drilled and chamfered 4 new holes between the others to match the 6 lug pattern. Center hole was 1/2" too small so torched it out 1/4" all around. Rim's are 3 pc split rims so u need to know how to work with those. Tires are 7.50x20. Can't fit anything bigger or they rub together and rub on the springs. Forget about the 8.25x20 - I have those here also and no way they will fit on the W300 axle. Wheels are 1/4 steel so was easy to work on and place sturdy welds. Also, to lock the duals together, welded lug studs to the inner dual in the 4 unused GM holes and placed lug nuts on the studs into chamfered holes on the outer dual. Did this in 1986 and put almost 200,000 miles on it since, w/o problems.

6 on 7.25 is what the D/W300s pattern is. i talked to an outfit that makes 19.5 dually rims that fit. 300 each tho. there are a commercial grade rim.
i can see if they make a 20 if interested.

6 /7.25 sounds better..been awhile, thanks. Pass on the wheels its a bit much for me.

a re drill of the larger 6 lug might work? larger pattern way more common

You can get that same tire from 14-20”... look at older Class A motor coaches. Big 6 lug 19.5” was dirt common. At least with Spicer 70 rear axles. I have 7 of those wheels, at least.

WD they will bolt right on? I've seen ford f600's had a 6 lug pattern, but from what i've read its a larger bolt circle.

Yes, much larger.

Missed this before.
I doubt if theres enough material for asmaller bolt circle. Theres a D500 cheap local to me that has some stuff i could use, when i go look at it I'll check out the wheels. He may have an xtra i can play with.

I wonder about that too. one off a GM medium duty might have a smaller hub hole. GM uses wimpy smaller bearings than dodge so wheel hub holes tend to be smaller. at least that is true on 1 ton and under.

Steve, see my detailed reply above about redrilling 20" GM wheels
