I am a newbie to RV world and will soon embark on first adventure from Ohio to Florida in 2016 Newmar Mountain Aire. I was lucky to get each axle weighed by the Ohio state patrol.
Front axle 9000 lbs/97000...Mid/tag/dual 9100 lbs/8600 ...rear 6600 lbs/6300. Front tires Michelin 365/70r 22.5, tag and rear 315/80r 22.
The current cold tire pressure in front tires is 110 psi. The tag axle cold tire pressure is 80 psi, and rear at 110psi. The tire pressure manufacturer tag/label behind driver seat advises 125 to 130 psi in the tires.
Michelin chart for tires advises as I evaluate the chart tells me front ok at 110-115 psi. Based on axle weight rear at 85-90 psi. What should tag and rear pressures be ? What say you for correct tire pressure. I thank you in advance for your help.
