RS-A vibration problems
Bought a 2014 Ford Taurus Limited with Goodyear RS-A 255-45 19 tires on it. Had vibration problems like the tires were out of balance. After two times of re-balancing and rotating tires, the Ford dealer found the right front tire had a ply separation in the tread area. They replaced the tire free of charge. Picked it up and it still vibrates. The dealer talked to a Ford Rep about it and he said he's been seeing quite a few RS-A tires with ply separations. The dealer has the okay to replace these lousy tires with Michelin Primacy tires.
It seems that Costco won't even sell Goodyear tires because of all the problems. The guy that runs the tire shop at my local Costco calls them Good(for a)year tires. He also recommends the Michelin Primacy tires. No more Goodyear tires for me.
