What do the numbers on tires mean? Many Wabash drivers may be curious about tire number meanings if they aren’t that familiar. We can answer that question at Greg Hubler Buick GMC! To help determine tire number meanings, read our guide below provided by our service department then use our tire finder tool to find the tires you need.
Those numbers represent the tire code, which is a combination of letters and numbers to inform you of the load index, speed rating, size, and type of tire your Buick, GMC needs for optimal performance throughout Hartford City. Here’s an example of the tire code:
Each section of the code represents a certain piece of information that you will need to correctly identify for your tire:
The “P” stands for “P-Metric tire,” meaning that it is used for passenger vehicles. If the tire reads “LT”, it means “light truck”. So, this tire would be put on lightweight pickup trucks.
So, what do the numbers on tires mean? Let’s start with the number “215”, which means the tire width in millimeters from sidewall to sidewall.
The aspect ratio code comes after the forward slash. In our example, this is the “65”. A tire’s aspect ratio is the height of a tire’s cross-section to its width. 65% of this tire’s height is equal to the tire’s width.
The “R” means radial, which indicates the tire’s construction.
“15” represents the wheel size from one end to the other, which tells us what tire can fit on this particular wheel. This code informs us that this tire can fit on a 15-inch wheel.
At the end of the code is “95H,” which is the load index and speed rating for the tire. The load index “95” indicates the amount of weight the tire can hold when properly inflated. The “H” represents the speed rating. In this example, you can go up to 130 mph in Gas City safely if max load capacity is reached.
