In January 2005 I purchased a set of Cooper Lifeliner tires for my Pontiac Grand Am. My car had 90, 000 miles on it's original tires so it was past due for new tires. I chose Cooper because they make a quality product and I was able to use a family member's employee discount. The Lifeliner is a great all season tire with a high treadwear rating, so it was perfect for my long distance commuter car. Currently I have 75, 000 miles on my Cooper Lifeliners and they show hardly any treadwear, I could probably get another 75, 000 miles out of them. They may outlast the car! The Lifeliners are quiet at highway speeds and instill confidence when you're driving through snow and rain. The only downside is that they lack the dry pavement grip of a summer performance tire. For the average commuter the Lifeliner is just about perfect.
