Steer tire wear

Depends on if he's running 14 ply or 16 ply steers. You can only go max 105 psi in most 14 ply steers. 120 is max psi for 16 ply. I would only go max pressure if it's up to max weight for that tire.

 

Michelin has a procedure for mounting steer tires, I believe it is on their website, see if you can find it. I have read at another forum where following this procedure cured similar symptoms. I would imagine the same procedure of mounting a tire to a wheel and hub would be the same no matter the tire manufacturer.

 

Then 100 psi is good if your running 11,500 -12,000 lbs on the front axle

 

Should be fine, that or 110. If you are driving deserts and heat, 100 is good. If up North, more mild climates, 100 to 110 is good too. Just watch scuffing those steers on the curbs.

 

WHAT??? 105 max.... wrong wrong wrong.
There is no max inflation rating on commercial truck tires...... go look at your side wall, it will list a psi, but that is the MINIMUM. Auto/Light Truck tires have sidewall maximums.
There is tons of info out there and on here about increasing your tires psi. Experts like Mike Beckett will recommend 120 psi on your steers. Running less than that is considered underinflated and cause irregular tire wear.
I have 160,000 miles on my Michelin XZA3+ steers, and have 10/32 of tread left. I keep them at 120 psi, have never rotated them. I had counteract balance beads injected at 20k miles. These tires have worn perfectly.

 

Bullsiht infomation!!!!!!!
Do NOT change your tire pressure based on outside ambient air temperatures. Always check and fill your tires when they are cold--- cold being in the morning, or hours after you have driven them.
Tires can exceed several hundreds of psi before they would "blow".

 

So, what do you think the weight is on the steer axle when you apply the brakes??? What do you think the weight on those steer tires becomes?

 

Have you even looked at the load /Air pressure chart??
It clearly states MAX LOAD AND AIR PRESSURE.



No where does it say MINIMUM.

 

Who cares what is on those tires when braking, they want to know what is on the axle when you roll across a scale.

That 100 psi for those weights is what Michelin recommends. Im sure the people who actually designed the tire know what's best.
