Tire Pressure for a 5.25 x 21 ?

Post by MbStew5755! » Mon Aug 16, 2021 7:43 pm

The front tires on my 1924 TT Truck are 5.25 X 21 . What is the proper tire pressure? The rear tires are 6.50 X 20 and say 50 LBS single and 60 LBS dully. Thanks Mark

I run 36 psi in 525/21s on my roadster on wood wheels and 20 psi on my Funster (weights next to nothing) on wire wheels.

Tire pressures recommended by Ford on the T cars and TT trucks, for the 21" balloon tires.

Text above the chart reads to be safe and add 2 or 3 more psi ;)
