I have not seen any brand tire in that size with anything more than load range E. Goodyear makes an LT235/85-R16, their G614 series, that is load range G and is recommended for trailers. To get the same load carrying capacity, you wouldn't need to change the rim because you'd still inflate to 80 psi.

Carlilse is producing an ST235/80R16 load range G but I don't know how available it is. Please understand I am in no way suggesting you buy this tire as I know nothing about it.

We, too, have the Goodyear G614 LT235/85-R16. It has been a good tire for us. Prior the that we had Chinese manufactured g-rated tires and experienced some problems. We run ours at 105 psi. The wear seems to be even after about 10-12,000 miles.

My small town dealer has to order them when I need them. If you don't have one, I heartily recommend a tire pressure monitoring system. We use the Pressure Pro and like it.

Stiles did you check into whether the wheels on your camper were rated for that much air pressure? I would like to run them too. Just wondering.

Two comments. I've got G614's and they called for 110PSI, not 80, so make sure about the weights you need. The other is directed at the Carlilse. Google that company and look at their track record. Never again on my trailers!

I too run G614's.
I have a letter from Tireco assuring me the wheels on our 2008 3400 have been re-certified to accept the 110 lb. tire pressure.

Turley: you may want to look at the Goodyear G614s since you are going to Alaska. They are fairly widely available (goodyear brand) so if you need another one, you should be able to get one quickly. They will be a bit taller than your X80s, but not by that much I wouldn't imagine.

washley1, the max air pressure listed on the sidewall of the tire is based on the maximum permissible load. Don't fill to that pressure unless you're carrying that kind of load or you'll affect the life and wear pattern of the tire, and bounce the rig around a lot more than you'd like.

If I put G rated tires on my 3400, I'd still put in about 80 to 90 psi because that's what the load tables call for. The slightly higher pressure (90) will reduce the rolling resistance and run the tires a bit cooler, and is suggested by some manufacturers. It also gives me a little margin of safety that the E tires don't have.

Yes, and so did my tire dealer. He doesn't want to get sued.

Firetrucker, Thanks for info. I have approached this thing looking at the maximum load for the trailer and truck,and not the actual weight. Guess I need to quit guessing and weight the rig!
