I don't know about Definity tires but I now have two of them.I had to stop at pep boys because of need.
The price of all the bogus charges more than doubled the cost of the tires. Goodyear tires won't charge all this nonsence, but buyer beware. And it took three hours to install two tires and there were only two other cars in the bays.
The peppy boys seem to spend most of the day shucking and jiving and playing with each other rather than doing their jobs.And they don't care what the customer thinks of their antics.
