Urgent: Need Tire Advice Class A Diesel
Today, Friday Sep 9, I had an incident and punctured a sidewall in Duluth MN. Currently I have Toyo 12R22.5 all around. These tires were installed in July 2010, so they have been in use for a little...

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. Not only am I mixing sizes, I'm mixing brands... Firestone and Hankook.
I agree with the above post if you can buy a used 12R22.5... put it on the back and go home. When you replace all of your tires I would SERIOUSLY look at putting 11Rs back on it.
