Tire rotations
As a general rule, I recommend you rotate your tires every 5,000-6,000 miles to get the most life out of your tires. However, tires can wear unevenly for many reasons. The most common reason is the alignment. With that being said, if the alignment is out of specifications, I would recommend an alignment as well. But for ordinary wear, without any front end issues, a tire rotation is all that you would need.
