Michelins...Porsches PSM System>>>
 

My 2006 Cayenne S has 15,000 miles...275/45R19's DiamarisMichelins...I suffered a front right blowout at 80 mph last Thursday evening...my praise is that the PSM worked so well, if it wasn't for the noise, I would not have known the tire failed! My criticism...the tire changing system needs to be simpler in my opinion...not a big problem if the flat happens during normal weather in daylight...but it is a problem when it happens at 22 degrees at night...anyway...Roadside Assistance came through perfectly. My question...these Michelins are all worn! I also have a 2004 BMW 7 series, and at 17,000 miles replaced the Michelins with Perillis...had lots of maintenance and wear problems with the Michelins. Now, in buying a new Diamaris for the front right tire, I notice significant wear in my other 3 tires at 15,000 miles...I always considered Michelin the best....now I don't know if I am just being unlucky or what!!!!! Should I commit to buying the other 3 Michelins, or what in anyone's opinion would work best? My driving is in Scottsdale AZ...great weather...city conditions...with monthly 400 mile round trips highway driving...any advice is appreciated.
