Running the fronts on most 25' or less Class C's at 80 psi per the door stickers {which are a bad joke}, will reduce the contact patch to the point that it will handle like a pig on skates and be blown all over the road by passing trucks and/or cross winds. Putting 80 in the rears would be serious overkill las at 80 they are rated for 2,640# of load X 4 = 10,560# to carry a 7,700# load. This also creates a very stiff ride that will beat you to death and shorten tire life.

Most Michelin tires for a 25' or less Class C would have a load rating of 2,470# in a dual wheel configuration. Please provide the tire size.
I stand corrected, with duallies the max load is less {not sure why} but even if it is only 2470 X 4 = 9880 to support a load of 7,700 { the ten percent fudge factor - 7,700 x 1.1 = 8470}. All four of my duallies are always aired to the same psi which is based upon the actual load they are carrying and typically varies from 65 when not towing or loaded heavy to 75 when towing and loaded heavy. Since the load on the front axle varies less I typically run them at 60 - 65.
My tires are all 225 75 16's and the last three I just brought are the new Michelin Agilis Cross Climate which were the successors to the LTX MS 2's and Defender series and have a max psi of 90.
