I just purchased a used 2006 Allegro Bay with Michelin tires, 235/80 R22.5.
Just wondering what tire pressures others have been using with these.

You need to weigh the rig after you have packed it and filled it with fuel and water as you would for travel. The using the tire charts from Michelin fill the tire with the right amount of air pressure to support that amount of weight. Have a front end alignment done at the same time. Everyone loads their rigs differently so what is good for Tom, Dick or Harry probably will not be good for you.

When you have weighed your coach go to the Michelin web site for the appropriate pressures.

Bloodman, welcome to iRV2.

You have received good advice.

Weighing your rig is the key.

Bloodman, welcome to iRV2 and congrats on your new motorhome.

The others have given you good advice about having the rig weighed. The best way is to get separate weights on all 4 corners and set the tire pressure for each axle for the highest corner weight on that axle. At the very least, get separate weights for the front and rear axles. Until you get the actual weights, you may want to set your tire pressures a little on the high side just to be sure you don't overload the tires. It may ride a little hard, but you will be on the safe side.

When we picked up our coach, the dealer had the maximum pressure of 110 psi in the tires. After having the coach weighed, I was able to reduce the pressures a good bit. That was when we used the coach for weekends. Now that we are full-time, we are again near, but not at, the maximum. I always a slightly higher pressure (+3 to 5 psi) than required just in case.

Hey Blood 'Exactly as "Paz" says!!! The only thing I would add is until you get her to a scale where you can get the corner weghts Inflate to your axle ratings!!!
I would think none if any newer coaches are over the axle ratings!!! Years ago yes but not now SO if you have a 13,000 front axle inflate to what Michelin says and if you have 20,000 inflate accordingly,
This will give you a safe and probably a fairly close atarting point!!!

In case of what??? A leak??? In case Michelin's load tables are wrong??

Michelin's RV Tire Guide says, "Overinflation, on the other hand, will reduce the tire's contact area with the road, which reduces traction, braking ability, and handling. A tire that's overinflated for the weight it's carrying is more prone to a harsh ride, uneven tire wear, and impact damage."

In case my gauge is off. This is the primary reason. Typical gauge accuracy is probably no better than +/- 3 psi.

In case I didn't get the gauge down tight on the valve stem to get a proper reading. Inside duals are hard to reach.

In case there is an undetected slow leak. Although I check pressures often, I don't check them every day. We are full-timers and may be traveling every day for several days.

In case our loading has changed since the last time we got the rig weighed. As full-timers, even though we try to keep things cleaned out, we still tend to accumulate too much "stuff."

In case the pressure is off due to temperature changes.

In case the pressure is off due to altitude changes.

In case the scales are off. They are certified, but not perfect.

There are reasons you don't want to be too far over inflated, but the bad things that can happen to an under inflated tire are much worse than the things that can happen to a slightly over inflated tire. I would rather err on the side of over inflation. In 26k miles, I have very even wear across the tread, so I don't think 3 to 5 psi is too far over inflated.

Wow Paz, you have a lot of concerns. With all your concerns the Michelin RV Tire Guide would be just about useless to you.

Good luck.

-Tom
I have a couple accurate gauges.
I can get my gauge on the tire stem for an accurate reading. I use a couple curved extenders.
I have no slow leaks and if I did I'd have it repaired.
I follow Michelins recommendations to check and adjust tire pressure in the mornings before driving when the tires are at ambient temperature. The tables are built for a wide range of temps.
Michelin does not factor altitude into it's charts and that is reassuring enough for me.
I believe a certified scale actually means certified. Read the weigh & measure certification seal on my weigh slip below.
I check my depth wear with a tire depth gauge 2 or 3 time s a year to monitor abnormal wear.
I have never had an RV tire failure.
I believe my Cat certified weigh slip below and I'm way under my CCC.
