Dunlop SP348 tire pressures

Posted this in the Fleetwood forum and thought I'd try here too:

OK, went to the local CAT scales and had my Southwind weighed.
Front axle = 6600
Rear axle = 11850

The placard in the coach says:
Front GAWR 7500 lbs
245/70 R 19.5 XRV tires at 95 psi cold

Rear GAWR 13500 lbs
245/70 R 19.5 XRV tires at 85 psi cold

I have Dunlop SP348's in that size and the placard on the tire says:

Max load single 4540 at 110 psi cold
Max load dual 4510 at 110 psi cold

Load Range G

I found this Dunlop brochure pdf, and it you go to page 5 on it, it basically has the same info as the placard on the tire.


So can anyone decipher how much air to put in my tires other than the coach placard of 95 front/85 rear?

Dunlop is a Goodyear brand and odds are heavy the tire specs are the same as equivalent GYs. I would use the GY table for your size if you can't locate a Dunlop load/inflation table.

The Dunlop Truck Tire Inflation Tables have your size but the max loads don't agree with your SP348 spec,
