I weighed my coach but I couldn't do the four corner weigh. The front axle is 6,520 and the rear is 13,300. I have Goodyear G670 245 70R 19.5 tires. I have looked at the goodyear chart but would like to hear opinions on the proper inflation. The reason I asked is that I just had it serviced and they stated they inflated all tires to 95 lbs. Obvously more pressure is safer but I normally don't carry that much air.

I use the same tires and have a similar coach weight (20,400 loaded). I weighed each wheel and wound up with 85 front and 82 rear, including a few pounds of safety margin. The manufacturer recommended 80 all around but I found it needed a few extra pounds in the front, principally because of some side-to-side imbalance. I have the exact weights in the RV if anyone is really interested.
I think 95 would be pushing it, especially since the wheels may not be rated for 95. And be sure you're weighing it loaded for travel.

Previously on every vehicle we have owned I inflated tires to the max written on the sidewall. Once when moving a mobile home from Tampa to Dallas for my first job the manager of my park (and a mechanic) told me to inflate the tires to 5 psi over the sidewall max. No tire problems reported by the mover.
But that was then and now tires are much better. I use the charts now and at our last TiffinRVnetwork rally I asked all attendees at a tech forum which they used and all use the charts.
But I do use my hand to feel all the tires for heat buildup when we stop for breaks. I would use an infrared thermometer if I had one.

It depends on what you mean by "MORE PRESSURE" I did not look up your tires but what ever it says for your weight I have always added 5 lbs to that. The reason why I do not agree in "way over" inflating is once I changed the tires a Neptune and increased the size a great deal. The garage put 105 lbs all the way around where it should have been 80 front and 75 rear. Well I almont got killed, besides feeling like I was driving on 6 rocks it was around 45 deg out and when I had to apply the brakes a little hard I went into a 6 wheel skid. Was told by Michelin afterwards I was real lucky and the dealer got blasted by Michelin. The tires being overinflated that much gives them NO adhearson in cold weather
