tire pressure
 

Can't find the tire pressure marking on my Firestone tires. Size is 4.75/500/19
What are we running ?

The instruction book says 35lbs

28 to 30 psig gives a better ride.

But "squishy" handling in my experience.

Good springs and shocks. Front end in good shape. 35 psi.

Reduced pressure just off sets other problems.

I agree it's 35 psi if everything is tight

I go off of the reservation and run with 28-30 psig. My 190A rides and handles nicely with this tire pressure. As for tire wear, I see nothing unusual.

My Model A tends to find the groves in the road and weave back in forth. I wish I had purchased radial tires. However, to put a slight bias to the front end I put 30 psi in the passenger front tire and 35 psi in the drivers side. This puts a very slight drag to the right and keeps the dead band in the gear box (about 3/4 in.) to the right side. It doesn't work for deep groves in the road but it lessens the minor side to side weaving. Ed

I get a kick out of some of these threads, they take on a life of their own.

Seems to make sense to me.....at least at first thought.

28 works for me

Set the tire pressure for the conditions you encounter. Ed in Maine is smart! and has the right idea for his situation, IMO. Less pressure (but keep high enough so you don't pinch tubes) works to reduce harshness on slower rough roads and provides a larger footprint for traction, higher pressures for cruising, easier steering, and optimum gas mileage. I've noticed with new tires and tubes, my '31 needs the pressure to be checked at least monthly as the tubes leak air faster than modern tubeless types (I suppose that can vary with the particular brand's tube material used). I run 35 lbs mostly, but 30 on the horrible back roads where I live - chuck-holes everywhere!

Cold 35 psi on a Tudor, 4.75/5.00/19, Ford spec. Station wagons ( heavier car hauling ) 40 psi
My last outing at a stop the tires looked low so I added air without a pressure gauge, when I got back I checked the pressure and it was 50psi, let some out to 35 psi hot. So now that it's cool I bet it's about 30 psi cold.
On a modern of mine the door sticker said 35 psi cold- 39 psi hot, if you drive to a service station to add air I would go 4-5 psi higher because now the tires are hotter. My dad's truck had 6 ply tires and we keep them at 45 psi because of over loading it, leave the warehouse with 24 window a/c the tires looked like radials and we put 60 psi in them, poor truck got abused. On the way back home dad said you know what your going to be doing for the next week, yep installing window a/c's.

Re: tire pressure
 

Radials would definitely have solved that problem, at least it they did for me.

Firestones for me, and I run 35 lbs cold
