The rear axle weight came in at 11020,.....so 11020/4=2755. Each rear tire. Once again, too low for the chart.......so either the weighing came in really low, and I had full fuel, tanks, and baggage loaded for the trip......what am I missing?
The lowest, weight to PSI numbers on the chart are the tire manufactures ABSOLUTE minimum air pressure allowable for the tire to perform properly. Inflate to that PSI and JMHO add 5 psi for good measure .
EDIT: Question, beside the tire sizing on the chart you posted , the second line highlighted, has a ( 1) after the tire size. What does that notation refer too?
Possibly a heavier load range tire ?
