I have no idea why on a 33' coach they put 12R22.5 tires. What pressures do you run in them... 85 lbs ??? My point is a 12R22.5 is way more tire than you need for your weights. I would go to 11R22.5 tires that have 492 revs/mile instead of the 12s 487... not enough difference to worry about. You would have to increase your tire pressures by 10 psi because the 11R has a little less load carrying capacity.
A 11R is a very common truck tire (your 12R is not a RV tire) and they may even have it in Toyo or Hankook for a lot less money. I would put two 11R on the front and get back to NC. I'm running six Hankook 11R/22.5 on the back of my DP because I did not need 295/80/22.5 on the rear for my weights. I'm running 315s on the front instead of 295s.
BIG rubber was installed on CC's because of an imbalance situation.....and when 10's and 11's were installed they bew some out causing wrecks.....hence 12.00 tires at 120 inflation front and 110 psi rear
