There are Chinese 20" tires available thru most big rig tire shops. I priced a set for mine at $200 bucks a pop about three years ago here in Houston. But I wound up having to go with 19.5" rims & tires all around when I swapped out my rear axle to get better gearing.

7.50x20 are tube type tires that are pretty skinny. I haven't seen one of those, new or used, in a really looooooooong time.

The Thomas model designator is not one with which I am familiar. I am not aware of any Thomas buses that were in service in WA state until the '70's.

In WA state the Gillig dealer sold Carpenters, the Crown dealer sold Wayne and Superiors, and there was an IHC dealer who sold Blue Birds. Even today the Thomas dealer for WA state is based in Portland, OR. As a consequence Thomas had no presence here in the '60's.

At a guess I would say the model designator identifies the model year and perhaps the wheelbase. What the 'D' stands for I have no idea.

I think they're available at specialty suppliers.

its interesting how regional busses were... when I was growing up (born in 6.. here in ohio you were almost shot as a school fleet director if you bought anything other than a wayne, carpenter, superior.. since they were built in ohio and indiana...

you would see a few thomas or bluebird here and there few and far between...

I didnt know of my first Bluebird until a friend of the family got a job selling them in 1980 to try and crack the midwest market... I remember I was 13 years old in the summer of 81 and he brought a "City-Bird" to my grandmas house.. I got to drive it around the block... I had just begun my fascination with school busses about then... so of course anytime he came to her house he brought a different bus.. which I got to make a loop in the subdivision with....

when superior left and carpenter went into re-org he tipped the midwest market with conventionals and made a $$$$$...

now for whatever reason IC seems to have ohio locked up... I see a few thomas / bluebird but seems 90% of the midwest busses are conventional IC...

maybe people still have some wierd loyalty to IHC since they at one time had multiple plants in ohio.. (including springfield that made a ton of conventional school bus chassis)..

I used to live in Ontario a while back and had a job in the 80s putting two way radios in about 300 buses and there were mostly Thomas, Bluebird and the odd Wayne.

I guess I will have to do some serious searching for tires once I get my bus back on the road. I have just asked at my regular tire places around here as yet. I was contemplating changing rear ends also but mine used to do 55 at about 3000 rpm when it was on the road before so around here that is passable. My little Hillman can do 50 at 3300 which for that car is really pushing it so my bus is kinda workable, but will have to do some changes once I do some serious travelling.

The body identifiers would be easier to guess if you could show us a front and rear view.

The side view tells me it isn't a Gillig, Blue Bird, or Superior. The two outward opening doors suggest Thomas. The wrap around the rear corner rub rail suggests Ward. The shape of the rear cap suggests Carpenter. Nothing suggests Wayne.
Hi, everyone;
Just got back from seeing my old bus I call "Barbie", and took a few pictures of her, so started an album of pictures, and also started a thread under "conversions" as "Barbie's refit".

Cheers,
Cliff

I'm With tango 63 is new I have a 1941 GMC on a 1.5 ton chasie The body is by Yellow coach of Pontiac mi just down the street from GMC. GMC bought Yellow to make the bus and special trucks. there is a GMC truck sight and Stove bolt trucks has info on old GMC. Most thing are different on GMC than Chevy even thou they look similar I believe your year still has a GMC 6cyl or a pontiac V8, On my year and not sure when they changed the wheel bolt pattern is different than Chevy, chevys will not fit I am in need of several rims my self only 5 bolt 7 hand hold wheels with a 6in hub opening fit. These wheel are hub centering not bolt centering. GMC was truly a heavier truck not just a re-badged Chevy
Good luck,
Larry

Hi, Larry;
I didn't know that GMC had Yellow Coach. There is always something new to learn each day but it is only logical. My bus has 750:20 tires, 8.875" between bolts 6.25" hub, but I didn't realize Chev and GM wheels are different. That is also good to know. I was quoted $300 per tire for Chinese tires including mounting and tubes in town from our local truck shop, and the engine is a 292 from what I have learned. Thank you for the info. I have been on Stovebolts site but don't have any info on the GMC site you mentioned and didn't even know it existed.

Cliff
