Reading Tire Sizes

Not all tires will fit on your car. The required tire specifications will depend on the vehicle you have. To understand what size your car needs, consult your owner's manual or check the sides of the tires you have now. There should be a code that looks like this: P225/35R19.

So, what exactly does that mean? Let's analyze the code a bit further to find out. 

1.  The First Letter: The letter at the beginning of the code indicates the vehicle type that the tire works best for. P stands for passenger vehicles (SUVs and sedans). Codes that start with LT indicates that the tire is best suited for light trucks.

2.  The First Three Numbers: After the letter, you'll see three numbers. This is the tire's width measurement. 

3.  The Two Numbers After the Forward Slash: The two numbers after the forward slash is the aspect ratio of the tire's height between the wheel rim and the tread and its width. In this specific series, the height of the tire would be 35% of its width.  

4.  The Letter R: The R stands for radial. This means that the layers within the tire flow outward from the center to the sidewalls. 

5.  The Last Two Numbers: Finally, you'll see the final two numbers. This indicates the wheel diameter that the tire is made for.

When you need new tires, you want to make sure the set you choose has the same tire size as the ones that are already on your vehicle. Selecting a set with just one number or letter off could lead to serious performance problems and, most importantly, damage under the hood. 

Choosing the Right Type of Tire

The ideal set of tires shouldn't just be the right size; it should also be the right type. Depending on where you live and your driving patterns, you'll need a specific type of tire to get you to where you need to go. 

Most people tend to choose all-season tires because they're designed to provide an excellent performance in almost all weather conditions. However, there are also winter and snow tires along with performance tires for enhanced overall performance benefits in icy, cold, and snow conditions.
