Whichever is your reason for selecting a tire, always be sure to get the best for your money and make sure the tire matches your vehicle’s performance. 

The size and design of the tires you choose should match that of the vehicle’s manufacturer.  The recommended size of your tires is printed on a placard on the inside face of the driver’s door or sometimes on the spare tire cover in the trunk.  The size is also on the sidewall of each tire and will be the largest numbers on the tire.  The size is always designated in a group of three numbers for passenger cars, pickup trucks and SUV's such as 215/65/16.  The first group of numbers designates the width, second set of numbers the sidewall height and third set of numbers is the diameter of the rim.  When to buy tires is a common question especially as the weather gets colder.  Tread depth and wear patterns will determine when you should buy new tires.  There are wear bars that are molded in between the treads of the tires when the tires are made.  When the tire tread wears down even with the wear bar, only 2/32" tread remains.  This is the legal amount of tread left before a tire should be replaced; however, when the tread reaches 4/32" it greatly increases the chances of sliding or hydroplaning in wet weather.  If you're not sure when to replace your tires, it's best to leave it up to a trained person.  Your life may depend on it!
