Dave's Tire Wear Thread

110 is the minimum psi for the maximum load...
12350 lbs is the maximum weight rating, some will say I never go over 12k lbs, but think about everytime you brake all the weight that is transferred to your steers, the more the sidewall flexes the more heat is generated causing irregular wear and premature failures... These low rolling resistance tires wear more consistently at higher pressures.

 

Now that I have the digital Tire monitors I can watch a lot more activity. It’s crazy when the seasons are changing such as now, how much difference a cold morning to a warm day will affect the air pressure. If you last aired your tires at 110 psi cold temp, when it was 60 degrees in the morning, and 2 months later it’s 40 degrees, there’s going to be a noticeable difference in pressure. I think I noticed about a 15 psi drop.

Kind of tricky in fall where it’s still 70 in the afternoon but 40 in the morning.

 

I will, 250k miles on my last set and 7/32 left when I swapped them out.....
and it doesn't say 110 max. Commercial truck tires do not list max psi. its max load at specific psi, and I as showed you the load range chart from Bridgestone its min psi.

 

so it didn't say 110 max???

 

The ride difference between 110 and 115 psi is very noticeable in my truck. I stay between 105 and 110. The ride is so much smoother and I've gotten around 200,000 miles out of 1st two sets of steer tires. This set I'm on now is close to that mark now and still have 1/4" thread. I've always run Michelins.
