The Stovebolt Site Forums The Parking Lot Big Bolts Advice on Tires and Wheels for my 6100

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?

I don't think you have a matched set of wheels. The photo of the steering axle with the Seiberling tire is one of the dangerous kind. You need to check each wheel individually because lots of wheels got changed around over the years. If they have a lock ring they are ok. If they split in the middle, they are the dangerous kind. They are 6 hole stud piloted

Where are you looking to say something split in the center? I've highlighted a section that I think you are talking about, can you confirm.

I obviously do have mismatched wheels, unfortunately I can't get at the right side of the vehicle to take better pictures of the other ones, I will check and document all of them when I get a chance.

I got some more information from my dad on the one Goodyear wheel that I posted above.

6.00S-20LBW

"The tire size would be 750X20, the rim is 20"X6
I think the letters mean, S=Steel, L=Low, B=boy, W=wheel."

MAX TIRE 8 25

"The max size of your tire in width side wall to side wall can not be more than 8.25. So you could put an 8.25X20 tire on the 6X20 wheel"

We located this entry in the Accuride Catalog

Accuride Page 18

Stud-Piloted Dual-Mounting
Double Cap Nut
6-Hole, 8¾" Bolt Circle, 6.50" Bore

Item 4
Wheel Size 19.5 x 6.00RW(2)
Part Number 29388
Hand Holes 2
Wheel Offset 5.00"
Disc .375"
Recommended Valve TR435
Approx. Wt. (lbs) 52
Maximum Load & Infl. (lbs) - (psi) 3640 - 110
(2) “RW” denotes revised well for increased brake clearance.

"I would go to the tire store on line and get the od of the 750X20 and than match that to new tires in the 19.5 wheel size and see what od comes close to your od. Low profile 19.5 is where I would start. For radial start with Michelin 12ply motorhome tires low profile. Maybe like 225/70R19.5 10 or 12 ply. Most tires will have a load rating by letter, 10ply would be E, 12ply would be F."

This is a search I did on TireRack: http://www.tirerack.com/tires/TireS...io=70&diameter=19.5&x=13&y=8

One possibility:

Found a 750x20 10 ply Bias Hwy TT with an OD of 36"

Ok, first things first. You do need to look at all the wheels to get the info you got on your Budd #60130. Like was said, wheels get damaged and changed over the years and you need to know exactly what you've got. The other thing about having a mixed set of wheels is the risks associated with mix-matching lock rings and wheels during service. All the dozens of lock ring designs used over the years have subtle differences and rings cannot safely be switched wheel to wheel.

My 1954 Budd catalog shows that your #60130 is, as you've posted, a 20" x 6" having the 6 lug x 8.75" bolt circle in a stud piloted mount. It has a 6 15/32" center bore (hole), and has 5.5" of dish. Recommended tire size is a 7.50", and max size is a 8.25". It has a Goodyear outer lock ring style rim (not a widowmaker) that has the technical design name of "LBW". Don't try to make anything else out of the letters, it's just the name of the design. Please see the 1949 charts in Grigg's tech article for the design. Also here's the LBW from Budd's 1954 catalog in my Photobucket file.

Before looking to go with a 19.5" tubeless I'd suggest keeping your stock 20s if they are safe to use. Next, if they are not, I'd suggest the Accuride #28157, a 22.5" x 6.75".

http://www.accuridewheels.com/studpilot.pdf

The 22.5" wheel is the correct tubeless size to replace a tube type 20". The 20" x 8.25" tire outside diameter will be a near exact match for that of a 9R22.5. Please see the below chart to understand the differences between a 5° tube type wheel and a 15° tubeless construction. Stu McMillan

Edit: I just remembered that I have a friend on another site that has a set of the 6 lug x 8.75 pattern 22.5s for sale. If you are interested I can have him drop by here. I have no financial connection. Stu

The Accuride #28157, a 22.5" x 6.75" lists it's Bore size as 6.50 and the original #60130 said it was 6 15/32, are those close enough to be considered equivalent? Difference apparently being "1/32" of an inch.

What tires would you recommend for my truck that weighs ~ 8160lbs by itself, and a GVW of 16K, 2 Ton Dually Rear, if I were to run the Accuride #28157, a 22.5" x 6.75"?

I don't really have an opinion on tires. There are so many to choose from. The narrowest 22.5 tire available though today is a 9R22.5 so I'd look at them. Maybe somebody has input on other metric sized tires too.

The 1/32" difference won't matter on a stud piloted mounting. On hub piloted it would, but not on a "ball seat" stud piloted mount like yours.

When you can get to your other wheels and have found numbers I'll look them up for you also. If you don't find numbers on some it probably means they are Kelsey-Hayes. They put their part numbers on a paper tag on the inner mounting surface below the tire. Doesn't help us much today. Stu

Edit - I just saw you're in California. My friend with the used wheels is in Ohio. A long way to ship. I'd have to think yards in CA would have a good supply of used six lug 22.5s. It's not yet an uncommon size. Stu

Now, if we could just find the 22.5's in the 10 bolt pattern!!??

I took a closer look at the the truck the two front wheels are identical, I can't find any markings on the wheel itself. The outside rears are the same Goodyears. No idea what the inside rears are.

Is there anything stopping somebody from mounting dissimilar wheels inside/outside on the rear?

No, that's the problem. As long as the mounting design is the same, any combo of rims can be teamed together. Stu

Thanks truckdog,

I finally got the new rims and tires on my truck.

After a long consultation, saving up for resources, and checking with several local tire shops I settled on Les Schwab. http://www.lesschwab.com/ in Livermore. My tireman was Jim McKee and he knew his stuff. He identified 3 of my original six wheels as widow-makers and he pointed out the features that he was looking for. I knew I already had 3 different styles of rims amongst the set and had it on good authority that at least two were widow-makers.

I really wanted to upgrade to single piece wheels with modern tubeless radials so what I settled on were the 22 5.x6.75 Accuride #28157 wheels that came stock in grey. I had Les Schwab powder coat them in black. The tires are 255/70R-22.5/16 Gladiator QR55-ST Highway and they are a perfect match for the old 7.5x20 tube-typed tires that used to be on the truck. The are a tiny bit wider but almost the same outside diameter. There's no rubbing at full steering lock, I couldn't have asked for a better match.

After getting the tires done it was time to go get some lunch on the way there I had to cut through the safeway parking lot and I noticed I had a stalker.

http://farm8.staticflickr.com/7136/7425547112_6964dc7851.jpg

This guy was halarious. He was soo excited he was fit to be tied.

He pulled up next to me as I parked at Burger King and he said he threw his wife out of the car at Safeway and chased me down. He had just watched one of the Cars movies that morning with his kids and he was just tickled with the truck.

So I popped the hood, and we talked for a good 30 minutes, he gave me his camera to take pictures of him with the truck, and I took a snapshot from my phone as well. It was a fun experience.

Outstanding! Looking great. My grandson will love your "Mater" too. Glad it all came together. Stu

That's awesome. These old trucks sure do make for some cool experiences.

You will be happy with the one piece wheels and modern rubber. Looks good
