If buying solely for the warranty then NO. Because what I found is that the tire warranty is absolutely useless. I bought 80,000 mile tires with 6 year warranty - in part because they were on sale, in part because of the mileage rating and in part because they were Michelin as opposed to no name and in part because hey 6 year warranty that's pretty good and worth the extra $20 per tire - right?

40,000 miles later my tires had dry rotted. Call place bought tires - I still had receipt - they were absolutely still under warranty. So I was told I had to call Michelin. Called Michelin. Okay tires are dry rotted - sides are splitting - warranty is only good if I can prove I had tires rotated every 10,000 miles and this and that and... "Okay, but the problem is the sides not the tread. Don't have a problem with the tread - still plenty of tread but my car won't pass inspection because the tires are cracked on the sides." Um, hmmm. How long have I had tires? about 3 years. I have to take to michelin service center to have a warranty inspection - can't take back to where I bought nope not at all so where is nearest center? - 50 miles away!

Make appointment. Then the rep (after almost 1 hr arguing on the phone with the guy just to get them to look at the tires because yeah, the problem is NOT the tread) he finally explains how the warranty works. They don't give you new tires, nope, that only happens within the first 6 months or if the tires completely fail (like completely disintegrate and only if you can
prove no road hazard). They give you a pro-rated credit toward the cost of new tires. After 3 years driving on the tires and because I had put 40,000 miles on them I got a whopping 20% credit toward the cost of new tires - oh and that was a 20% credit off the full retail value and had to be purchased directly from Michelin and that was only if the inspection at the tire center proved they were at fault for the defect and not my driving (driving causes dryrot??) or storage of the car (ooookay) - add to that frustration the big kicker the new model of tires they now sold to replace the model of tires I had was on sale for less than that at BJs.

So basically I found out the warranty on tires is USELESS after 6 months.
