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.

http://www.goodyeartrucktires.com/pd...20Brochure.pdf

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,
