Bridgestone Dueler H/L Alenza P255/55R-20 107 H Tire

I purchased the tires with 10k miles on my Silverado in 12/20. I've driven 31k highway miles on the tires, rotate them religiously at oil changes and maintain proper air pressure. The truck is babied (not driven fast or hard) and is primarily used on lengthy trips. Rarely is it driven around town locally. Tire wear is fine, but they have gotten very noisy with vibration at highway speeds, and has gotten to the point that I don't want to drive it on trips until I replace the bad tire or tires. Apparently, one or two have gotten out of round causing the noise and vibration. I bought these tire for the reviews and better handling than the factory tires that came on the truck from the factory. Until the vibration and noise, the tires were great; handling and comfort was good. Was hoping to get more than 31k miles out of them.

Tires were on the truck when I purchased it new, rotated every 5,000 miles and now need to replace them already, tire dealer measurements: 3/32, 2/32, 0/32, 2/32. Waiting to see if they will back the warrantee, not impressed with the Firestone Manager, he told me the rating was only 40,000 not the 65,000 it should be.
