Uniroyal Tiger Paw Touring A/S All Season 205/60R15 91H Passenger Tire

I knocked off one star because with just two cars in the Walmart shop, it should not take 1-1/2 hours to mount, balance and install 4 tires. Durability - too soon to judge If you're not familiar with the tire ratings, "Treadwear, Traction and Temperature" do a quick search on them. These Uniroyal tires were rated as follows: Treadwear 700, Traction "A" and Temperature "A." They're well worth the extra twenty over Walmart's Douglas tires. Uniroyal is a subsidiary of Michelin. These tires are a big improvement on handling and run noticeably quieter than the tires they replaced.

I bought a set of 4 in 2018, they were a great tire until this year with about 50% of the tread left the cords began to separate and they developed flat spots I replaced two about a month ago and just replaced another one today for the same reason. The first pair have been returned to the manufacture for inspection and I am awaiting results. I live in Ca. Central Valley so I wonder if the heat could be an issue or is it a Manfacturing defect.
