We have 2 sets of tires for our Classic S. One All Season set and one Winter set. The All Season we bout last year at the end of August. Today we were told they needed to be replaced when we went in to have them rotated. The tires have 24k miles on them and the tread life warranty is 35K miles. The tire shop refused to prorate our tires claiming that it's out of alignment and the evidence for that was bad tire wear on the inside of the tires. My wife took it in today as I work nights and sleep during the day so I haven't yet looked for myself at the tires. We will be replacing them with Cooper tires which I've always had good luck with on my previous car. Not a high performance tire but a well made economical tire so we will see how they perform. Is there any way to prevent this from happening again? We usually inflate to 50 psi but admittedly outside of summer we do pay as close attention to keeping it at 50psi. It never gets below 40psi or at worst 35 psi. Any suggestions? I will be calling the tire manufacturer to discuss this with them.
