Tips for Buying New Tires
1. Before you decide on a new tire, ask yourself these questions:
What tires are currently on your car?
Did you like your old tires? (Smooth ride, good handling, long wearing, etc.)
What do you want your new tires to do?
How important is crisp handling and quick stopping compared to smooth ride or long wear?
What kind of "look" are you after?
2. Determining your correct tire size:
Look in your automobile owner's manual and you will find the size fitted on the car originally. Unless you have changed wheels, that's the recommended size
The tire size is written on the tire's sidewall. Here's an example of the way tire sizing looks on the sidewall:
2.1. P indicates a passenger (car type) tire. Other options would be: no P indicating metric sizing (essentially the same as P-sizing, which has its heritage in Europe) or LT for light truck. LT truck tires are designed for heavier loads and more rugged service conditions.
2.2. Width of the tire, in millimeters. The higher the number, the wider will be the tire.
2.3. Aspect ratio.
The height of the sidewall section compared to the width of the tire. Example - if this number was a 50, then the tire section is half as tall as it is wide. Short sidewalls deliver crisp handling. Tall sidewalls give a smoother ride. For a specific tire width, the smaller the number, the shorter will be the sidewall.
2.4. Construction. R indicated radial construction.
Unless you specify the other option, bias (which would have a D (diagonal) or B (belted bias) in this position instead of an R), you are purchasing a radial tire.
2.5. Wheel size designation. This indicates the distance across the "doughnut hole" of a tire - in simple terms. You must match wheel diameter and the tire opening. A tire with a 15 size designation will not work on a 14" wheel, and vice versa. Improperly matching of wheel and tire size can cause serious injury or death during installation.
2.6. Service description.Includes the load index (a number) and a speed symbol (a letter - see table below). About load index, remember: keep the number the same as or greater than the original tires' load index. That number stands for a specific weight carrying capability. Key is that the higher the number, the greater load carrying capacity. So keep the number the same or higher, because your tires are matched to the weight of your car. Never choose a tire with a lower load carrying capacity that the original equipment tire size.
Now the speed symbol. It means the tire is speed-rated on an indoor test wheel to:
We recommend that the replacement tires match the speed symbol of the original tires since these matches the speed capability of the vehicle.
3. Uniform Tire Quality Grading (UTQG)
The Uniform Tire Quality Grading (UTQG) is a system developed by the Department of Transportation which helps consumers compares tires in the areas of treadwear traction and temperature. Here is an example: a tire with a UTQG of 300 AB. The 300 is tread-wear, which represents the tire's comparative wear when measured against the government-mandated tire, which is rated at 100. So this tire wore three times longer than the control tire. Because of variations in operating conditions, the treadwear grade cannot be used to predict actual wear out mileage; it can be used to predict the relative wear rate of tires with different UTQG wear rates.
Traction and temperature are graded A (superior), B (good) or C (average). Traction indicates the level of grip the tire possesses.
Temperature rating deals with the tire's ability to disperse built-up heat. Heat causes rubber to deteriorate over time, so dispersing heat increases tire life.
Each tire manufacturer determines UTQG rating for their products. Realize that UTQG's are more accurate when comparing tires within the same line versus tires form two different makers.
