Whether you’ve examined your tires or sought replacements from a nearby tire shop in White City, you’ve probably encountered a sequence of numbers and letters on the sidewall. Naturally, you may be pondering, “What do the numbers on tires mean?” This alphanumeric code serves to convey vital information about the tire, encompassing its size, type, and specific performance attributes. Whether you’re navigating the tire market for replacements or simply curious about the significance of these markings, let Capital GMC Buick | Regina be your guide in unravelling the mysteries behind tire numbers. Check out the tire number meanings below.
A tire’s code employs a combination of letters and numbers to convey essential information about the tire’s size, load index, speed rating, and type. Understanding this code is crucial for you or your Regina service centre to identify the precise tire specifications your vehicle requires for optimal performance. Consider the following code as an illustrative example:
Although it might appear confusing, each segment of the code corresponds to a specific piece of information necessary for accurately identifying the tire type.
The designation “P” signifies a “P-Metric tire,” indicating its use for passenger vehicles. In contrast, “LT” on your tires indicates a “light truck” designation, specifically designed for light-weight pickup trucks. Tires without a letter preceding the code are European-style, or Euro-Metric tires, distinguished by their distinct load capacities.
After the “P,” you’ll find the number “215,” representing the tire width in millimetres from one sidewall to the other. In our illustration, the tire has a width of 215 millimetres.
Following the forward slash is the aspect ratio code, denoted in our example as “65.” The tire’s ratio represents the height of the tire’s cross-section to its width. In this instance, the tire has an aspect ratio indicating that its height is 65% of the tire’s width. A larger aspect ratio results in larger sidewalls.
The “R” signifies the tire’s construction, with “R” denoting that it is a radial tire.
The “15” denotes the wheel size from one end to the other, providing information about the type of tire suitable for this specific 15-inch wheel. This code clarifies that the tire is designed for use on a 15-inch wheel.
Concluding, the code is “95H,” signifying the load index and speed rating for the tire. The load index, denoted by “95” in this case, specifies the weight the tire can support when appropriately inflated, ranging from 75 to 105 for passenger vehicles. The letter “H” signifies the speed rating, indicating the maximum speed the tire can safely handle based on its load capacity. Speed ratings are categorized by different letters, and in this example, a tire with an “H” rating is capable of reaching a maximum speed of 209 kph.
Ensuring your car’s tires are well-maintained for optimal performance on White City roads involves keeping them adequately inflated. The process of checking tire pressure has become swift and convenient, particularly with the prevalence of Tire Pressure Monitoring Systems (TPMS) in most modern vehicles. The TPMS alerts you to any over- or under-inflation of your vehicle’s tires. If needed, a quick visit to a nearby gas station allows you to top off the air in your tires.
