How often should I replace my tires? 

Tires need to be replaced for different reasons.  When a tire has worn down tow 2/32nds of tread it should be replaced.  If A tire is 6 years old it should be replaced.  Any defect or irregular wear pattern is an indication a tire should be replaced.
 

How will I know if my tires need to  be replaced? 

You can read the age of the tires by looking at the DOT number on the tires. The last 3 digits of the DOT number give the week the tire was manufactured.  The first two digits of the last three indicates the week and the last digit indicates the year. Example  a DOT that has the last 3 digits with 182 would indicate the tire was manufactured on the 18 week of 2012. Another way to determine if your tread is worn down to 2/32nds of tread is by looking closely at the tire and finding the tread wear indicator. The tread wear indicator can be found in the circular groove between the tread. It is a little rubber marker that looks just like it is part of the tire.  When the tread wears even with this marker it is time to replace the tire. Also on inspection of the tires if you see any cracking or bulges on the tire it could very well indicate an unsafe tire.
 

Why does my tire pressure matter?   

Tire pressure is very critical to proper tire wear and safety. An under inflated tire will cause premature tire wear.  It can also cause excessive heat build up and can cause tire failure under certain circumstances. It will also decrease your fuel economy. An over inflated tire can cause irregular tire wear patterns and can cause the ride to be uncomfortable. It is recommended to follow the tire pressure recommendations from the manufacturer for best performance. This can be found on most vehicles by opening the driver door and locating the label that shows recommended front and rear tire pressure for the vehicle. Some vehicles used to carry larger loads have a loaded and unloaded recommendation. Depending on the load and weight you are carrying determines how much air should be in the rear tires. The door label will indicate the two pressures recommended.
 

How often and why should I rotate my tires?

Rotating tires helps keep a smooth wear pattern on the tires.  This will increase the life of the tire and ride quality.  It is recommended that tires be rotated at least every 6,000 miles.  Certain vehicles with aggressive tread designs may even need more frequent tire rotation to ensure a more even wear pattern.  Example a Mud terrain tire benefits from a tire rotation every 3,000 miles.
 

Should I change my tires when the seasons change? 

In southern Arizona we usually do not have a need to change tires due to seasons change. Most tires are an all season tire.  Which means they are good for most conditions. In areas of extreme cold such as ice and snow a studded snow tire is required.  But in southern Arizona that is not normally required.

What do the letters and symbols mean on the sidewall of the tire? 

Example: P205/65r16. The first letter in this example represents a passenger tire. Another example would be a LT 285/75R16. The LT represents a light truck tire. The first number 205 or 285 in these examples represent the tread width in millimeters.  The next number in these examples 65 or 75 represent the aspect ratio. This gives you the sidewall height. This is calculated by dividing the aspect ratio  65 or 75 into the tread with. The letter before the last number which is R represents the type of tire. This indicates a radial tire. Almost all tires a radial tires. The last number represents the diameter of the wheel the tire is installed on. It is measured in inches. In these examples both are a 16 inch wheel.
