I have 93K on my 2010 S and about to get my 4th set. I bought the car at 28K miles and the dealer replaced the OEM tires. They lasted 32K miles with rotations every 5K miles. I cannot remember what they were. I replaced them with General Altimax RT43's and love how they handle wet and dry pavement but they are ow worn to the bars with only 33K miles on them. Anyone else having this issue with different tires wearing down to quickly? Also anyone having great success with tires that run less than $500 installed. I am on a tight budget now so Michelins are out.
