air pressure

[allen]

Hi two questions one what is the right pressure for 21 inch I read all about 30 inch which looks to be 70 psi, this beings up my second question how did they use that air pump to get 70 in the old days must have been a work out HA ha thanks al

My 21 inch wire wheels take 35 psi. The wood rimmed tires are the high pressure ones.

That would be the 30 inch tires would get 65 LBS and the 21 inch tires wood or wire get 35 LBS.

They made a dual tube air pump for those 60 lb tires....still would have been a workout..rbg
