I always run heavy so I drop the tires to 50 pounds so I can get more product on my truck.
How much PSI are you running in your tires?

I currently have my steers at 105 and 90 for the drives.
The picture below is 105 psi. I didn’t like that. So aired down to 90 psi which fixed that.
I’m still on this set of tires so far.
The live bottom and end dumps I have them at 105. The lift axle is 120.
I have been thinking of increasing the pressures from 105 max to 110 or so for these trailers as they’re always heavy. The tread is wearing more at the outside instead of near flat across which is telling me they need more air.uncleal13, Rideandrepair and Midwest Trucker Thank this. -

Look up the load inflation tables that the tire manufacturers have on their websites. You’ll basically find steer tires are pretty much carry a full load at all times and need somewhere around 110-120 psi. Drive tires never carry max weight and some manufacturers may say as low as 75 psi is fine.
Use the manufacturers recommendation as a starting point. Then adjust higher or lower as you see what sort of tire wear you experience in your operation. -
125 steers, 105 on drives and trailer
John Bertucci Thanks this. -
120 steers and 110 drives
John Bertucci Thanks this. -
Anything over 105 on my steers, makes my Truck ride hard. I’m wondering if you guys running higher pressure on steers have air ride on front axles. From what I understand, the higher the speeds ran, the higher psi needed, to keep the heat down. Same principle that causes a low tire to blow out, or a cap to come off.
