What are the best Tires?
Gerald Farris:
Gary,
If you go to the Michelin website and look at the load and inflation tables for your tires, you will see that if you have 90 PSI in your tires the maximum load rating for your front axle is only 10740 pounds if you have LR (load range) G tires, and 11390 pounds if you have LR H tires. These weights are a lot under the 13200 that you should have on that coach unless it weighs that much less and I doubt that.
The proper way to set air pressure in your tires is to weigh the coach and adjust the pressure by the load and inflation tables for your tires. Until you weigh the coach, the safest inflation is to use the maximum inflation that is on the tire sidewall.

Gerald, why not just run the tires at the maximum pressure all the time? Can a person really tell the difference in ride quality between a tire at 120psi and 110psi? I don't think I could. Seems like an awful lot of weighing and adjusting.
Gerald Farris:
Adam,
Everyone does not feel the same as you about tire pressure. Some owners are looking for as good a ride as possible. Personally, I agree with your view point. My coach should be running 110 PSI to 115 PSI, but I like to error on the side of safety so I run 120 PSI in all tires. However, if my coach was lighter or if it had a tag axle, and I could run a lot less pressure, I would probably reduce the pressure. But I would still run 10 PSI to 15 PSI above the recommended pressure.
One of the reasons to weigh your coach, especially the 2002 models and older, is to be certain that your tires are adequate for your weight even at maximum inflation. My 2000 Marquis came with 11 R 22.5 tires, and when I weighted it, I found that I only had one tire (the right front) that was not overloaded at 120 PSI. So I replaced the all most new tires (I received almost half price on the 11 R 22.5s for trade-in) with 295/80/22.5 tires for the extra load capacity. I have had a blowout on a motorhome before, and I do not want another one. That made the peace of mind gained from the extra weight capacity worth the price of tires.

We had a 1991 Baronett that had a wear problem on the front and going 10 psi over chart pressure at he reccomendation of JoSam in Orlando cured abnormal wear problem.
Gary Winzenburger:
Gerald, this is all very, good information. After looking at all the information and the tires I have on the front of our Marquis, I will get it weighed as soon as possible. My tires are rated at 6175 LBS at 110 PSI, so I'll add air up to 115 or so hoping they will carry the 13,220 lbs if the front is that heavy until I can get them replaced.
Thanks,
Gary
