I have a 2007 MDX that came with 19" rimms and low profile tires. At 18,000 miles I had to put new tires on this SUV. I was told by the dealership that 19" tires have a wear problem. I am on my 2nd set of tires and experiencing the same wear problems. I rotate and balance at 5,000 miles. Has anyone else experienced similar problems? I would appreciate any advice. Thanks.
