Purchased 4 Definity ex600 tires for wifes 2002 Malibu in late 2007 at the Willow Grove, PA store. They were perfect.
Quiet, handled good, snow O.K. Pep Boys claims 80,000 miles. They went 80,000 miles and one inch! WOW, never went that far.
Never rotated.....ever. Never needed air.......ever. AND CHEAP. Even the sidewalls looked great with NO maintenance after 4+ years.
She only ever puts gas in her car.....typical. I don't understand all the complaints. They will fix anything, even if it's not their fault. Plus at buy 3 get one free, what do you need to think about.
The only problem I see is ussually Pep Boys stores are near malls. So, while you wait for installation you'll spend too much at the mall.
