What should the tire pressure be on my 26/27 wire wheels? New tubes, old tires!
I would say anywhere between 30 & 35, your preference, much like a modern tire.
30-35 lbs works for me.
I have been running several sets of wire wheels for many years at 32. The tires seem to wear evenly at that pressure. I doubt that running a little more or less would cause any issues.
I think I read that ford sez 27/28 lbs, I use 32/33 works for me.
27 in the rear, a little less in front.
The tires bounce with any more air due to lack of shocks or dampers.
A model A with the same tires takes 35, but they had shocks.
Actually being a wire wheel has nothing to do with it. It's the same pressure as the 21" wood wheels!
