What tire pressure should I be running with goodyear mt/r's? The tire says it has a max psi of 50. I can't seem to get it right. Also, if I have a different psi in the two front tires, how will it affect my steering? I have a pull to the left and thought that may help out. One more question, does anyone know if these tires are directional? I'm not sure if I can cross the fronts to the back when I rotate. Thanks for any info in advance.

Whatever the tire has printed on the sidewall. Inflate cold. Do not exceed this pressure. If you're not running the same brand/style of tire, you'll feel the difference (different tire pressures) in the steering first.

Vehicle will pull towards the lesser-inflated tire (more rolling resistance)

What load range are you running? E should have 80 psi as the max if I remember right.

My goodyear MT's are 285's and have a cold pressure of 65psi on them. I have right at 90000 miles on them, I am currently trying to figure out what to get before winter though, its about time for new tread

Wait a min here, you sure they're MTR's? My old ones that are now horse feeders say 80#. Never got more than 35,000 mi outta a set, same with Extra Grips.

These are MT/R's, 305/75 R16, load range D. It says on the tire, max air pressure 50. i thought that was pretty low. I'm trying to get the toe in adjustment right, so the fronts won't wear so fast. if i'm looking at the tires from the front, should they be a little toe'd in or what?

XLR8R

Yes, as opposed to toed out... but do you trust your eyes to align your rig?

I know a trick to align 'em
jack up each fron tire, then get a nail and spin the tire while holding the nail in place,then measure between the lines,front and back of the tire want em toed in just a lil.
could not tell ya how much though..cause I used that trick to align the logtruck...but it should work
And I run "D" load range on my dualy too, I have 255/85-16 on and its a little smoother than those E's

XLR8R

When we low-buck a toe-in alignment issue, we place a long straight edge across the rear tire all the way past the front tire and measure away.

Never tried this on a dually...

According to this page, your 75 aspect ratio doesn't exist. Perhaps it's a 70?

A "D" range tire is nearly always an 8-ply rated, where the required "E" tire for CTD's is a 10 ply rating. 50# is low, but not for a "D" tire.
