Ford of Canada Service Bulletin, June, 1925: "Balloon Tire Inflation:
Sedan, 30 to 33 lbs
Coupe: 24 to 26 lbs
Touring: 26 lbs
Roadster: 22 lbs

If the Canadian pound is the same as it is in the United States, I think those are too low. I like to use 32-35 pounds in mine. So far in 30 years I have not had a bad wear problem. I also use 60 pounds in the clincher tires.

Yeah, me too. In both my ‘26 roadster and ‘26 tudor I’ve had great luck with 32-34 pounds. They’re 21” wires.

Here is the label affixed to one of my new Goodyear tires I recently installed. It says not to inflate over 40 psi, so I inflated all 5 of mine to 34 psi so the tires would be soft enough to allow the tires to take up some of the shock and relieve the springs of the shock experienced on rough roads.

it really does depend on the car weight - I run 28 lbs. in the lighter cars - 32 lbs. for closed cars.
