Anyone know the standard tire size for the 1950 Desoto in general and the Carryall in particular?

I believe they are 750x15
Ralph,
The tire size for 1950 DeSotos with the 125.5 wheelbase which includes the Carryall was 7.60 x 15 for a wheel rim width of 5.5". For the 139.5" wheelbase eight passenger and Suburban models, the tires were 8.20 x 15 for a 6" rim width.

Thank you for the quick reply.

In todays tire shops they refer The 8.20 x 15 Tire to The
235 x 75 X 15's. These are Radials. They will not "woller
around" as the 8.20's - you will get an better MPG than
8.20's and at an event The Radial's will not get an minus.

Here in San Francisco I do a lot of driving and parallel parking. The modern radial tires make it a pain in the ass to move the steering wheel while barely moving.
I went to a set of 700R15's. I got these as whitewall tires from Diamond Back Tires. The tires are in fact from Yokohama and are their light truck tire. I think the Yokohama number is RY208.
I have used them for several years now as has a friend on his '46 Town and Country. I emailed Yokohama and asked about the pressure range as they are listed as 60 PSI tires. They told me that if used on a classic car that does not require the maximum load handling that the tires are rated for to run the pressure down (30 PSI Minimum) so the ride is not too hard. I use 35 PSI for daily use and if I am making a freeway high speed run (65MPH) or if I load the car with 9 people, I then run it up to 55-60 PSI.
The only problem any of us have had is that I have a set of disk brakes on the front of the Suburban and I had 2 of the custom wheels crack due to stress at the weld between the center and the rim. I also was trying to keep up with a bunch of classic Ferraris and Maserati's on a New Years Day Car Run up the north coast.
We welded the wheel center on both sides and since then no more problems have happened. My friend with the T&C and the original wheels has not had any problems. Keep in mind that the Suburban with a full load runs around 6500 pounds...
The whitewall tires via DBtires runs about $275 with shipping, whitewall beauty ring, road hazard and the like. I think you can get the Yokohama tires from you local tire guy for about $170 each but they have all the modern crap on the sides.
The diameter and the contact patch on the tire is almost exactly like a stock bias tire and the steering feels like I have power steering compared to a "regular" radial.

Because "The Foot-Print" of an ole design tire vs
an like diameter radial is more with the radial than
an 1950 designed tire - The Radial will always be
harder to turn while not moving. It is ( to me ) the
biggest difference of non rolling quality.
With our De Soto I use 215 x 75 x 15 "All Season" Radials
because it is the closest diameter to the tires that came
on the car.

Roger, That is why we like the 700R15 radials. The contact patch is 4 inch which is what the orginal bias pky tires were. James
