Optimum Inflation Pressure vs What Drivers Want
Posted by Tim on December 2, 2005
If the tire manufacturer recommends that the tire should be inflated to 110 psi and the drivers like to run them at something less than that, how do I get optimum wear (from a fleet owners aspect).
The optimum pressure that a tire should be running is dependent upon the load it is carrying. Since the load being carried by a working truck is varying all the time, the optimum pressure is also varying.
Tire manufacturers publish an inflation pressure based on the maximum load the tire can carry. If you are like most fleet owners, your trucks are seldom (if ever) running at the maximum load their tires are capable of running. So, running tires at a pressure slightly under the pressure recommended for the max load should not be a problem.
Most line haul fleets have inflation specifications between 95 psi and 105 psi. Running in this pressure range should result in acceptable tire performance.
