My question: Per Goodyear’s inflation charts and my weights I should be fine running about 90 PSI in the front and 85 PSI on the rears. The max pressure for the G’s is 110 and for the F’s is 95. Since my inflation requirements are 85 & 90, I see no reason to run higher pressure. Should I get a softer ride running 85-90 in the G’s than the same pressure in the F’s which have a max pressure rating of 95? I called Goodyear and their response was to always run the max, 110 which I fell sure is not correct.
I don't know who you talked to at Goodyear, but you would think that they knew what they are talking about. I was told to run my MH tires [Michelin] just short of max. Not to go off the issue, but I have Bridgestone 32" tires on my Jeep and I had heard so many different things about air pressure that I called them. They suggested airing them half-way between the door sticker PSI and Max on the tire. They said that this was for road use and not off-road. I got 45,000 miles on the tires doing that. I could have gotten another five to ten thousand, but I like more tread even though they were not near the wear bars.
I know...I am going to get chastised for not weighing the MH, but this is what I was told. The tire companies, like Michelin, talk about weighing the coach in all their info, BUT when you call and talk to a rep you get a different story.
I also spent some time experimenting with what I read online for optimizing tire pressure at this link and I got very close to the same result as I got above.
Optimizing Tire Pressure
Am I going to get it now!!!
Happy trails, Joe
