Our rev's wheels are max 120psi cold. I just did a four corner weigh and need to calculate what my pressure should be on my front tires. According to my build sticker, fronts 120 rears 95. However, my front weights were much lower then axle rating so likely don't need 120psi.

I need to hunt down the site to determine what I should inflate the fronts to.

It is standard.
Truck tires were rated by number of plies used in the tires construction. These are now rated by letter, G,H etc and reflect the equivalent strength of the tire carcass. A load range G would be equivalent to a 14 ply tire and H = 16 ply. (Even though they only have 2 or 3 plys in the sidewall. Some only have 1 steel ply) Load range also determines (or is determined by???) max inflation pressure.

Good discussion.

MY Michelins haven't blown out either, but after seeing an rv in a tree (and having no idea what tires, age, condition were on that unit) it just made me want to open a point of discussion.

In my opinion, the tire brand has little to do with tire problems. I do believe the RMA Rubber Manufacturers Association's assertion "over 90% of all tire failures are the result of underinflation or overloading". All tire load/inflation charts reflect the absolute minimum pressure for the corresponding load.

The only blowout I've had was on a Goodyear RV670. The reason it blew is that the tread separated from the casing causing the tire to blow. I have a set of Michelin XZA3's on order for immediate replacement.

Just my 2 cents, but I don't think you can find a manufacturer out there that has a record of zero blowouts. If I had to guess most tire failures are due to either a road hazard, under inflation, or over loaded. I would also guess that a small percentage are manufacturers defects, as they do happen. I also do not think Michelin is a better tire than any other tire out there, nor do I think any other tire is better than a Michelin. I do think Michelin's are overhyped and overpriced.
There are many brands out there, just make sure they are the right load range, check them every morning before you take off, and hope you don't run over a piece of debris that will puncture it, and try to protect them from UV. Other than that, not much else you can do, it is in the hands of the tire god's.
