I changed my first set of Bridgestones at 25K miles. I was hoping the next set of Michelin Pilot Sports AS/3 would last longer, since they had a 45K miles warranty.

A nail in one of the tires made me take a look at the tires, all of which had worn down to 5/32" tread depth. These were Z rated tires, that wore out in 18K miles.

Just replaced them with Y rated same tires. $910.

Is it Michelin, or just my bad luck?

Sigh!

 

Not Michelin or your bad luck. A 4500 lb luxury sedan with aggressive alignment settings is not going to achieve stated tire life with any tire. Most members seem to have tires last 20-25k miles.

 

As dal stated, that is normal wear....especially a Z rated tire.

 

You should try running higher treadwear touring tires instead of high speed rated ultra high performance tires. That will help some.

 

same here, Michelin Pilot Sport AS/3 wear out in 20k miles.
per warranty, Costco reimbursed like 40% of the original new tire price I paid.
not too bad.

 

I love Michelin buying tires at Costco because of the warranty........ Just remember to rotate them and check pressures AFTER you get an alignment.

 

Correction: the new tires are Z rated too. Discount tire matched Costco's prices and gave me a refund on the tire I had not even bought from them, and their warranty gets you a new tire in case of a road hazard claim. I also find their customer service better than Costco. So now all 3 of my cars have Discount Tires! I used to be a loyal Costco customer, but they are so popular, to quote Yogi Berra, that no one goes there any more!

 

Discount Tire is a great tire place. I've had very positive experiences with them. Excellent prices and good service.

 

Except they don't do alignment!

 

Neither does Costco.

 

Yes they do. They will do free rotation and alignment if you buy the $29 replacement certificate.

 

No. That's a rotation and balance.

America's Tire Co. does not do alignments.
