tire pressure

[armadillofz1]

I did a search and checked the FAQ, nothing. i have a singled deuce on 11x20 tires. what pressure should i run in these things. the fronts are cupping severely. the PO put 50 front and 100psi rear. sounds a little extreme to me. i'd like to rotate them and adjust pressures. i also noticed some light sidewall cracking, but i understand this is fairly normal.

While the tire cupping is most likely the ft shocks. I think on the dash palte it tells you the psi.

these tires are not the stock bias ply tires, so anything on the dash plate, if it was there, wouldn't apply. these are the michelin radials. i'm sure the shocks aren't helping the cupping but i just can't get behind a 50 psi difference between front and rear.

I would always put more in the front than in the back. I would look on the sidewall ratings. For highway driving max in the front and 20 to 30 less in the rear.

thanks

I would always put more in the front than in the back.

I was told this as well.

My local Michelin dealer wasn't familiar with military tires, but their general advice was to carry about 15 p.s.i. more in the steering axle tires.

if you're running civy tires we usually put 90 in the fronts and 100 in the rears, but i'm talking gravel hauling . if you're talking empty, i'd run 80 lds all around.

I have the 395's singled out on my deuce. I have gradually increased pressure to 65 psi all the way around. For the deuce running empty this seems to work well.

Off road I am running 15 psi. This has given great traction and more cusion to the ride.

just rotated my tires today (feel like i've been hit by a truck). running 80 in back 90 up front. took it for a spin and it feels better than before. seems to steer better with more air upfront (im sure the non-cupped tires up front now helped) do they make street tires (tractor trailer type) that will fit the 20" rim? i think that would be the way to go.

I have singled Firestone T831s, direct from the Military that came on my truck. The truck's unit had TP-50 stenciled on it. I increased it to TP60, and find that it rides very smooth with little to no bounce empty, and still is good on fuel economy. Here is a pic
