We bought four new tires due to a lot of driving. Put on 2012 Taurus. Ride is bumpy. Kept having tire pressures checked to get a smoother ride. No luck. Five months after purchase, still brand new tires - developed a slit next to rim. No relief from Michelin Tire. I paid nearly $500 per tire but was expected to purchase hazard insurance for another $30+ per tire. We paid a good price for supposedly "better" tires - should not have to purchase insurance too!
