I have Optimo H727 on both my PT Cruiser and Explorer. I have 56,000 miles on the PT Cruiser Optimo tires and expect to get at least another 10,000 so I plan to get close to 70,000 on the tires. They are listed at 100,000 but I will not get there with these tires. They are great all season tires for the price. I had Michelin on my Explorer before but they were over $300 more than the Hankook Optimo tires. I am please with the tires and recommend them. Consumer Reports has the Optimo H727 rated as a Best Buy.
