My brother was also in the tire business for 40 years and also ran a Bandag recap shop for large truck/bus tires. He recommended I replace my 11R22.5 Toyos with Bridgestone R250 295/80 R22.5 and stay away from Goodyears. His choice would be Bridgestone first, Michelin second, and Goodyear third.
His logic was that Bridgestone has 1) similar ozone/UV repelling compounds (and they work best if you don't put tire shine on them); 2) a deeper tread depth and longer tread life, 3) the same or similar load rating, and 4) stronger casings that stand up to more abuse. His preferred used tire for recapping was Bridgestone, because of the casing, and he said it carried the most value in the used truck/bus tire market for that reason.
I replaced the Toyos with the Bridgestones 11,000 miles and a little over a year ago on our Coach and was amazed at the improvement in ride and handling. I was also able to lower the tire pressures from 120psi front, 110 psi rear, to 100 front and 90 rear. This helped the ride, but the different tire profile on the Bridgestones also helped the ride and handling. My Toyos were showing abnormal river wear on the tires by the time they 10,000 miles on them, and had to be rotated. The river wear continued up until I get rid of them at 31,000 miles. The Bridgestones, now at 11,000 don't show any abnormal river wear, so I don't plan to rotate them.
Since then a number of my friends with similar coaches have also replaced G670 Goodyears with the Bridgestone R250s and are very happy with them.
You might want to consider the Bridgestones instead of either Goodyear or Michelins.
