What pressure for new G614
I changed out the Marathons for G614 today. My wheels are rated for 110 psig. What should I be running the new tires at. I know the tires are rated for 110 but should I be concerned with the 110 rated wheels if I inflate the tires to 110 knowing that when they get warm driving they will be over 110 psig?

With our 3455 we have been running at 95PSI, cold of course.

I've run 108# for several years. Pressures can go up to 126# running on a hot summer day. No problems at all.

We run ours at 110 psi. Remember, all the ratings are for cold inflation, so the tires and the wheels are designed to handle the increased pressure from driving. Might as well take advantage of the higher pressure, has to reduce rolling resistance and help with mpg. The trailer actually handles much better with the heavier tires at the high pressure.

We run ours at 108 to 110 psi. When traveling, when we stop for a rest, etc. I try and make the rounds on all the tires and check for temperature. Before starting trip we always check for unusual wear, defects, etc. just in case.

Any gauge you buy has a notation on the package: +/- 5 psi. So I air up at 105 just in case mine is + 5 psi.

Ditto on the 105 here. As soon as we register any miles at all, the TPMS stays above 110 which is fine with me. A double ditto on the pressures ranging upwards of 120-125 when we are on the road for extended periods.

110 PSI cold as recommended for me as well. The coach is loaded almost to gross weight, therefore I want max pressure in the tires.

110 PSI, max pressure cold. Tire engineering allows for the increase in pressure as you drive. Max air allows for max load capacity.

There is a chart out by Goodyear I think , that we have got at the fall rally. It suggest tire PSI based on the weight on each wheel. The PSI being equal the highest weight measured on any one of the tires. Who knows what their individual weight is on each tire every day???
we are at 105psi..we just are...and we have no idea what our individual tires loading weight is..

Wow! Glad to see this. I was just looking at the recommended pressures on my first Fifth Wheel and thought, "Can that be right?" Much higher than I would have guessed.
