Barney, Where do you keep the pressure when not towing? Just put new Michelin LTX M/S-2 on. Max pressure is 80.....Chevy says 50 front 80 rear on the door sticker....tire dealer says 65 front 80 rear.....prior to the tire change I had been following manufacturer...all the time so the rears were always at 80.

I don't change the pressure between towing and not towing. I keep the fronts at 75 and rear at 80. I do keep a bunch of "stuff" in the back of my truck all the time however, and also have a cap on the back which is heavy. In addition, my truck is a 7.3L diesel which is quite heavy. I find the ride acceptable while not towing. I use the truck only for towing, but it is our daily driver while wintering in Florida for at least three months every year. I do not get any unusual tire wear.

Barney,
Thanks, that confirms what I was doing previously and so I'll just continue on leaving the pressure the same all the time.

I would follow the manufactures instructions. Otherwise you can always use a load/inflation table that can be acquired from the tire manufacturer. To use this you need to weigh your tt and then adjust the tire pressure according to load. I am going to assume that the tt manufacturer has done this already using the tt's gross weight to cover themselves for liability sake.

Almost all of the tire failures I've heard about were caused by "under-inflation," or "over-loading." Never heard of one that was caused by "inflation to maximum pressure listed on the sidewall." I always keep my tires inflated to the maximum listed on the sidewall of the tire.

While I agree with the above statement in regards to under inflation causing problems, overinflation reduces the contact area of the tires which is also unsafe, it also wears the tire faster and creates an un-necessarily bumpy ride. The PSI listed on your door jam or on the info tag on your camper lists a pressure that the manufacturer deemed appropriate, the listing on your tire sidewall is the pressure that the tire manufacturer has deemed maximum.
