We have a 2013 Winnebago Aspect 27K Rv and would like to know the correct tire pressure. It is on the Ford E-450 Chassis and has Michelin tires. Thanks

Tire pressure depends on the load range of your tires and how much weight the RV is carrying. There are 4 methods to determine the correct tire pressure:

1. Use the maximum pressure found on the tire’s sidewall.
2. Use the maximum pressure values on your Chassis manufacturer's namplate, usually located behind the driver's seat; confirm your tires are in accordance with the chassis manufacturer's specifications.
3. Calculate the pressure using your rv's axle weight and tire's inflation/load charts; confirm your tires are in accordance with the chassis manufacturer's specifications.
4. Calculate and set the pressure at a safe margin above the rv's actual loaded axle weight from a weigh scale and tire's inflation/load chart. This is what I do for an rv.

I run 70 pounds front and rear. I also inflate my rear air bags to 50 pounds both left and right. I quit trying to make it ride like a car years ago but those numbers seem to work most consistently for my 2014 27k.

I no longer tow a toad, but used to take a Jeep Wrangler everywhere and those inflation numbers seemed to work fine. Had both a 2008 JK Rubi and a 2013 JK Rubi, both 2-doors, with same experience.
