Rotating your tires is a painless DIY task and helps extend the life of your tires significantly. Each tire on your car wears differently and rotating the tires allows all four tires to wear in a more uniform fashion. Rotating your tires also provides you an opportunity to inspect your tires for irregular wear and make sure they are properly inflated.
Rotating your tires involves jacking up your car and taking off one wheel and moving it to a different location. Check your owners manual for guidance on what position to rotate each tire to. It is important to look at the side of your tire to see if there is a 'direction' arrow, if there is, that means that the tire can only be rotated from front to rear, but must stay on the same side of the car. Many shops include free tire rotation for life if you get new tires from them.
