Tire Pressure ??

[Rick 2005 Dolphin 5376]

Our Dolohin 5376 weighs about 25,000lbs. Our 22.5's say to inflate 110lbs max at full load. The tires are rated to carry 4950lbs for a total of almost 30,000lbs. I'd like to soften up the ride a bit. Would 90lbs be enough to soften the ride and still be safe? What else could I do to make long distance cruising a bit more comfortable?

The only way to know what pressure is right is to know your individual axle weights (better yet, each wheel position). Then check the mfg tire charts for your specific make and model of tire for the individual axle or wheel position weights of your motorhome. The fronts probably will require a little more pressure than the rears ...my fronts require 5 psi more than the rears based on my weights.

Try this Michelin site for their charts. I am running 95 front/90rear and it's tough on a buppy road.

Thanks, I found a chart on Michelin's web site a few hours ago. I'm going to adjust pressures after I go have the MH weighed next week. I'm going to weigh overall, front, rear, fr, fl, rr and rl at a friends scale.

When you weigh it make sure it is loaded for a trip. Supplies,food,fuel,passengers,etc.
