VCCA Home Forums TECHNICAL - 1945 AND EARLIER 1912-1928 27 tires

Can anyone tell me if these are the same as what a chevy truck would use (at least the tires) or do I need to reach out and get the actual tire size?
The person has 2 for sale for 50.00. They are off a Willys Whippet, and they don't look to shabby compared to what's on the truck I'm getting.

You have to know the size. If you were going to try to substitute something not right but close, you would have to at least know the rim size.

There were 2 tire size numbering systems in those days, one system tells you the rim size right in the size number on the sidewall, the other does not and you have to calculate it.

For your '27 one ton truck, the original size was 30x5 (old spec that measured the outside diameter and the tire height). So, deduct 10 inches (2 times 5") from the 30 and you get the current equivalent of 20 inch rim and 5 inch height (20x5).

I have 30x5 tires on the front of Lurch and 20x6.50 on the rear. That way you go a wee bit faster. ;-)

It's hard to see the tire size in the photo above, so it's hard to say if it will work.

Is the chevy truck a half ton or a one ton? If it's a one ton you'll have 20" rims (assuming they are correct) just as Dean describes above. If it's a half ton, I believe it will have 21" rims like the cars.

We'll learn more today as it's come home day. Going to be an adventure. I guess I was just hoping if anyone knew if Willy's and Chevy used the same wheels by chance. I know there both 12 spoke wheels and I thought maybe that was a clue. I thought I remember from a thread somewhere where Dean talking about counting the spokes, and being able to tell what chassis it was (1/2 vrs 1ton) I don't think I have seen any wheel though with less than 12 spokes.

. Passenger and commercial (AKA: half ton) used 30 X 3.5 on wood spoke wheels for Roadster and Touring, 29X4.40 with wood spoke wheels for Coach and 29 X 4.40 with steel Disk wheels for Coupe & Sedan in 1925 and 1926. In 1927, all passenger cars used 29 X 4.40 on Disc with wood optional on all models. In 1928 all used 30 X 4.50. Passenger and commercial have 4 lug bolts holding rims on as pictured on whippet. . . .
. On the Utility (AKA: One Ton trucks) from 1926 - 1928 used 30 X 5 = ( 5.00 X 20 ) with 32 X 6 = (6.00 X 20) as optional. Utility continued to use 20" rims till the advent of radial tires when they started using 19.5" rims on the 3500 HD in 2002. Utility have 6 lug bolts holding rim. See photo attached.
. Note that different width rims were supplied with tire options.

This is exactly the wisdom I was after. Thanks Lou.
Truck is home. I will have to start a build thread with photos. Obviously I need to find some tires.

So with understanding a bit more about tires I've still been on the hunt. I found the below on ebay. I don't get the double number on the tire of 4.75/5 Is one number the rim width, and one the sidewall dimension? I'm thinking that at least one set of these would work as fronts. Could put a set on the rear for rollers, and later change to the larger diameter tire for a "wee bit more speed" I have not reached out to the seller yet to ask if they hold air, but my hope would be that there are tubes and maybe flaps that are salvageable.
I know the wheels are different, but would the locking rims potentially be the same being they are 20in?
I'm also curious being that they are they same diameter if the spokes could potentially be the same for the fronts. I know they don't look near heavy enough for rear spokes. My existing front spokes are pretty good, but these for sale look a little better.
My felloes are not the greatest around some of the bolt holes either, but I am hopeful I can add some new metal and fix them up.
Thanks a bunch for your patience.
Sorry I couldn't figure out to make the link clickable. Have to copy and paste.

Hello David,

Being those are hydraulic braked drums I suspect they very well may be '29 Chrysler. Probably mid range like a model "65". The model numbers for Chryslers of that era were how fast it would go. They used Wagner Lockheed aircraft type brakes. Regardless of what the seller tells you - Buick didn't use hydraulic brakes until '36. The banjo nuts are identical to the ones used on our '28 model 72 Fisher bodied Chrysler coupe. That was the last year of the contracting band type. You may be buying something you can not use on your Chevrolet. Being complete axles, would work really well for a speedster.

Thanks, The more I look at the pictures the felloes look narrower so therefore the rims would be different also. I suspect that the tire designation of 4.74/5.00 is much like how they classify lawn mower tires these days. giving the sidewall height and rim width, so the tires are likely too narrow.

Did Chevrolet trucks and any other trucks share rims?
For example right now someone has a set of 4-brand new tires with what looks to be new tubes (6.00x20), wood spoke wheels that they started restoring with great spokes and felloes, and the rims on ebay , but it says they are for a model AA which is Ford Truck.
The felloes don't look the same as mine therefore I assume the rims are not the same. But 12 spokes from a 20in wheel, do they have the potential to be used on a chevy wheel? And then the tires and tubes would be a good score other than two not being slightly larger for the rear for a little more speed.

The 4cyl 1 ton trucks used either Kelsey-Hayes rims(pre1928),or Jaxon rims from '28 up.Both type of rims use a different rim tool,and won't fit ford AA trucks,though the 6.00 X 20" tyres will fit.

Thanks for the reply. I'm still thinking on this latest find. If the price could be right it would be well worth it for just the tires and tubes. Still being 20in I wonder how different the spokes might be? Like I mentioned the ones on the rear of the listing do not appear as heavy as the ones on the rear of my truck.
Not that I am going for 100% correct on my restore job so just curious if anyone has adapted or know if the ford style spokes and or felloes/rims could be adapted by changing out the hubs to the chevy ones?

The rear wooden spoke wheels are Chev truck(the 8 hub bolts are the giveaway)as are the front ones.They're either off a 1926 -1927 R,X,LM series 1 ton truck,or a 2 wheel brake 1928 series LO 1 ton truck.The rim locking method(just a pin through the eyes at each end of the split)makes them the Kelsey-Hayes type split rim,and the felloes have the square hole for the rim bolts,whereas the LP/LQ Jaxon rims,use a rim clamp bolt with an oval under the head.

Can anyone else confirm CJP's take on this that the listing is for wheels to fit a Chevy truck?
David

I suggest getting in touch with the 1927 - 1928 Truck Tech Advisor that is listed in the G&D. They are listed in the back of the magazine, just before the classified ads.

So I bit the bullet and bought the rims and tires. I got them for a great price that was well worth the 4 brand new tires, 3 new tubes, and 3 flaps.
I figured if the rims were not right I had nothing to loose.
They showed up today and CJP was spot on. The wheels and rims are basically the same as the rims currently on my truck other than the fact that my rims are the Jaxon type with the rim clamps with the slot. The wheel bearings, races, and screw on covers from my old rims all fit the rims I just got. I need to try the rear wheel hubs yet on the axle, but I suspect they will be the same.
The wheels have spokes that look like they are brand new. All steel has been blasted and in primer, (some in paint) rear drums look like they might possibly be new ones etc. Tires still have the date code ink stamp on. Simply an unreal deal.
All 4 new tires are only the 600 x 20s. Will still be on the look out for some 6.50 x 20 for the rear for that little extra speed. Also will probably need to track down 2 more rims (as I only got 2 with the deal) I recently picked up 2 very nice Jaxon rims from a fellow member, but IDK if the Jaxon rims will fit these Kelsey-Hayes wheels?
Will also need to track down the right rim clamps and bolts.
Very happy :)

The Jaxon truck rims will fit the Kelsey-Hayes wheels and vice versa,the profile of the rims are the same.The differences between the 2 types of rim being the rim locking system,Kelsey-Hayes use a locking method using a single pin and the driving lug for a rim bolt is offset,the Jaxon truck rims use a similar rim locking method as a passenger car rim with the turning lock tab.The other differences are,the Kelsey-Hayes rims have 1 pair of holes holes on each side of where the ends of the rim meet,Jaxon rims only have 1 pair of of holes.This is because the correct truck rim collapsing/spreading tools are different.

CJP,
I did try to slip the Kelsey Hayes wheel fellow into the Jaxon rims I just picked up from fellow member, but they didn't seem like they wanted to go. I did do some measuring on the Jaxons, and they seem like they are a little out of round so I am thinking that could be why, but not sure. I did measure the rest of the profile of the Jaxon rims compared to the 2 Kelsey-Hayes from the ebay sale, and they do seem to measure up the same otherwise. Just the locking method and the driving lug being different like you say.
Will have to track down the correct lug bolts, and rim clamps. I did note the different quantity of rim holes also like you mention.
Thanks for your input on this, it's been very helpful!
