Tire pressure and temperature recommendations

You need to know the weight...at each corner or at least each axle. Then you can check the tire manufacture's chart for those weights. If the tire pressures are right the temperature doesn't matter unless it changes drastically

What do the MH and tire manufacturers recommend?

I have 2007 Allergo 32BA and I run 95 psi in all the tires, and my gross weight is 18,000 lbs.

My MH weighs 19,000 lbs loaded, and I run 80psi in the front and 85psi in the rears. Based on both the Toyo and Michelin tire tables and the true weight of the MH.

I would add that it needs weighed while loaded for travel.

Thanks everyone. I don’t see a way to get it weighed before I drive it, but the idea makes me want to pull into a scale pretty quickly.

Have bought tires for millions of miles. Over inflated will make it ride rough. And might have a little affect on handling. Under inflated will ruin a tire in a short distance.
Assuming you have a good compressor I would air up to max sidewall, stop by Cat on your way first day. Then after tires cool, and before next travel day adjust to chart.

Any Pilot/Flying J will have a scale. DON'T BE INTIMIDATED! THEY ARE THERE AND WILL HELP YOU! Pull onto the scale, placing each axle on each scale. Put it in neutral and release the parking brake. There is a microphone to talk to the cashier. Tell them you're an RV and want a weight ticket. They will tell you when they are through. Takes about 30 seconds. Pull off the scale and go inside for your weight ticket. Adjust your tire pressure as per mfg recommendations.....four corner weighing is best but it's more expensive and harder to find someone who will do it. Axle weighing is next best and will give you enough info to properly air your tires. Altitude and temperature will also affect PSI in your tires so adjust for that if traveling. I set my PSI twice a year (summer and winter) and rely on my TPMS while traveling.....Dennis

Thanks for the help! This trip does have a dozen or so miles on an interstate so I’ll be looking for a scale.

Remember if you have been driving, pull in to weigh your snot, and adjust the pressure, next morning, when your tires are the same temp as outside air, you are setting on underinflated tires. Within a hour you might be setting alongside the road
