Mastercraft Posted September 13, 2015 Report Share Posted September 13, 2015 I have these Kelly drive tires, G rated. They have a statement on the side that says something to the effect - " For speeds above 60 MPH, add 10 psi with no increase in load capacity" I don't need more load capacity with 26K on the rear, I have checked the rear tires with an IR thermometer and they run relatively cool just a few degrees above ambient without doing the 10 psi. What's the deal with this add 10 psi thing? thanks Rich Link to comment Share on other sites More sharing options...
