If the tires are all the same size, then i would stay with that size, the different tire pressures would probably mean different ply ratings. I would go with the higher ratings, but have the rims checked for maximum inflation recommendations. Hope this helps you.

It's nice to have the same size all around but make sure the rims will work with thoses tires. Mine won't work with those. I have 8Rx19.5 and rims 19.5x6.00

It is usual for the front and rear tires to require different pressures (psi). That's because the load (weight) on the tires is different.

Why is it you think that 245/70R19.5 is not the correct tire for your coach? The front tires need to have enough load capacity to carry the maximum front axle weight, which should be listed on a placard near the driver seat. The placard is a federal highway safety requirement and I think it was in effect in 1999. A typical 245/70R19.5 tire will carry about 4500 lbs of weight, so if your front axle is 9000 lbs or less that is probably an OK tire for it.
