Tire pressure
Just noticed, the sticker beside the driver's seat mention a tire pressure of 100PSI all around. The sticker in the cabinet above sink says 90 PSI all around. Now which is right? What do you follow?

I would go by what it says on the tire sidewall.

Why is 110 worse?
I am kind of sure the tire manufacture knows more about their product than the people who built the chassis or the ones who built the box now sitting on it.
One of the worst things a tire end user can do is run it underinflated.

In my Berkshire, sticker says 120....but that is for the max. pressure. I was taught that tire pressures are based upon the loaded coaches weight. I had mine weighed at camp freightliner, and with that load I was told that I needed 95 in the fronts and 90 in the rears. They readjusted the pressures and the coach road smoother and the handling was better than when I had the 120 in them. There are some more knowledgeable people on this forum that can weigh in on it.

Berkshire wants their coach to ride nice, tire companies want their tires to last. Tires not to max inflation wear faster, so if you want to replace them at a faster rate, inflate them at Bershire's recommendation. If you want to prolong the tire replacement date, go with the tire manufacturer's recommendation, max inflation.

Tire pressure
Ford Idaho I am saying worst because as they are 100PSI my TPMS after about an our on the road it shows tire pressure of 118-120 PSI. Therefore if the were at 110PSI cold, I am assuming that when I hit the road they would be as high as 130PSI.

Only worry about the pressure when cold, it is normal for the pressure to go up as heat builds, the tires are built to handle the increase.

Tire pressure
On my Berkshire dealer set them at 110. Wanted to wander all over the road. Had coach weighed Dropped all tires to 95 as per weight. Handles like a dream now.
My guess 90 or 95 on a Georgtown & you will handle much better. Maybe as low as 85

tilap, did you get a tire guide from the tire manufacturer when you purchased the coach? I got one from goodyear and it shows the process of calculating weights (by weighing the coach at the axles...front and rear or each corner) and from there determining what the inflation pressure should be.

My friend has one. Don't have my weights in front of me now but I run very light no junk or extras in my basements. Before I weighed it I started dropping the air 5 pound at a time. Then test drive. I actually had the best ride & drive the lower I went. I finally brought them back up to 95 and left them there.

Ford Idaho. I understand that pressure go up as the warm up etc. but there should be a limit as of how high it can go? My understanding (which is limited) is when pressure/temp goes to high you end up with a blow out?

Gasman, no I didn't but while doing research on line I found one. My plan is to get that done when I get out of here (northern Canada) pretty limited for scales around here. But I got a long way to go before I get to one, so trying to stay on the safe side till I get down south.

Denis, If you can find corner scales (weighs each individual wheel), this is the best. These scales are hard to find, so you may need to weigh each axle and set tire pressures accordingly. Good luck...

Tires blow because they are underinflated, overloaded or suffer from internal defects caused by running over a curb or hitting a pothole.
The biggest cause of tire failure is the end user (you/us/we).

Take your gross weight per axle as stated by manufacturer then go to the tire sheet for the tires you have and size, the sheet will tell you what the pressure should be for each axle by single or duel and this will be for a fully loaded to the max camper, Toyo states my 22.5s should run 80lbs which I found 85 rides and handles best.

I would not even consider running 80 lbs on my truck tires. 65 is way more than I need and the tires wear just fine.

We are talking about a motorhome I believe.

I am not too knowledgeable but I sure would not drive my Motorhome on 65 PSI tires. Yes I think he didn't realized we were talking about motorhome.
