Ah, you bought your truck used !!!
If those are not the stock tires, then the tire placard is useless

what exactly are your michelins ?
Do a google search or look on tirerack for inflation pressures...

but agree, without any other info I would put 45 or 50 all around since you don't know their load ratings or your weights ...

The side of your tires should say what the rating is @ that 50 psi --- what is it ?
ASSume they are all the same tire? with the same ratings ?

Yeah, I'm going to go with 45psi in all 4.
Johnboytoo -- I bought the truck new, not used. The tires came with it. I guess it was an upgrade... nicer tires, nicer rims... you know.
The tires say they are 50 r20.
I checked that chart but couldn't find my tires. Also wasn't sure what my wheel diameter was but I'm thinking it's 20 because of the 'r20' in the 50 r20.

You should keep all 4 tires at the same air pressure if it says u can go to 50 psi i would keep pressure between 45 and 50 on rear tires and not less than a 5 pound difference in front when towing. Not sure what ply tires you run but i dont run anything but 10 ply especially for towing tires dont heat up as much and last a lot longer definetly worth extra cost.

Looks like someone replaced the original tires and rims. I would inflate to the highest psi on the tire sidewall, should be 50 per Michelin website.

Yes you are on the right track, You need to set them CLOSE the max on the sidewall while towing and put them back down when you are not. 35 sounds good when unloaded. As other have said tire weight capacites are determined by how much air is in them. They WILL prematurly fail if you overload them without enough air to compensate, also it will Tow much better and less sway.
As for your front tire question the answers is simple; do you have a weight distribution hitch? If so then you need to increase the front tires also, maybe not as drastic but the hitch is transfering weight to your FRONT tires as well so without weighing each axle with and without a trailer attached I usually pump the fronts up 10 to 15 psi as well.
Hope this helps clear it up..

I would go back to the dealer and ask them to tell you the correct inflation. They changed the tires from stock.

Most dealerships do not know enough to give accurate advice when considering towing. I would find the complete tire information on the side of the tire. If I had to I would look on the inside of the tire if you can't find it on the outside. Should be close to the dot marking.

The tire size most likely starts with a p, then 3 numbers, a back slash, 2 more numbers then the r20.
so something like Pxxx/xxR20.
