I know this subject has been talked about many times and I have read posts and looked at inflation tables until I was cross eyed. The problem is I have Cachland 295/75R22.5 CH-111 tires and cannot find a tire inflation chart for them. Yes I know they are Chinese tires and probably not the best quality tire but that's what I have and they are near brand new.
I have looked at just about every major tire inflation chart and they are all over the place from 80 -105 on the fronts and 80-95 for the rears. The mobile tire installer initially had them at 120 psi front and rear and it rode like a rock wagon, I have been lowering the air pressure 5 psi at a time trying to find best tire pressure for ride and wear. I am currently at 100 on the front and 95 on the rears. Any comments or advise would be appreciated. Oh my heaviest front side is 5940 lbs. and rear 9760 lbs.

Thanks

They have some technical info and warnings on their web site. But I also could not find an inflation chart by tire.

Perhaps contact them for your specific tires.

They have a 'Tire Usage Tips' section
*Weigh your vehicle and its load,axle by axle,to determine tyre pressure.

But NOWHERE do they provide a load chart

They have phone numbers listed...International ONLY

Good Luck!

Not helpful for the question you asked, just thought you might want to read this. I found it on Amazon while searching.

“•The Cachland CH-111 is a commercial all-position tire is optimized for steer axles. •Designed for regional and limited highway service applications, the CH-111 delivers superior versatility on a multitude of vehicle platforms.”

I would drive straight to a michelin tire store and spend the money for good, SAFE tires. The damage you will do to your coach (body panels, wheel, air lines etc) when you have a blowout will cost you a lot more than what you saved.
Chinese tires are total 5hit tires. Sorry to be so blunt but if you have ever seen a coach with a blowout, scary stuff....

Assuming all tires of the same size have the same weight/load ratings, here's a Bridgestone chart that lists that size tire.

Thanks, I do have this chart but my problem is this chart says I could go to 80 psi on the front and 90 on the rear but Hankook and Goodyear charts say 105 for the front and 90&80 on the rear

guess I will try to contact Cachland.

Ok I think I found my answer, I talked to the folks at RVSEF and was told to try to find a tire chart with the same max load PSI that is on my tires and go with that chart. Sure enough Firestone, Toyo, Yokohoma ect. all have the same pressures. Thanks for the replies.
