A quote from one of many articles on the topic: "An overinflated tire is stiff and unyielding and the size of its footprint in contact with the road is reduced. If a vehicle's tires are overinflated by 6 psi, they could be damaged more easily when encountering potholes or debris in the road, as well as experience irregular tread wear."



The 6 psi was in reference to a car tire - equivalent to something like 20-25psi in our big tires.



Since the proper inflation of a 315/80R22.5 could be as low as 85 (typical tag axle) or 90 (typical drivers), going to 130 is 40 to 45 lbs too high!
