I was surprised that my tires needed to be rotated after purchasing new in 11/12 w/ 50,663 miles. The warranty from Alexander tire said have wheel alignment at least twice a year and rotate tires every 5,000-7,500 miles. There was some wear on tires, I was told. So, I'm wondering if the tires weren't installed properly or is there something in my driving that rotation was needed far before normal additional mileage. Thanks.
