THE most important part of your car is your tires. And yes, I did mean to capitalize “THE.” Tires are literally the only part of your car that touches the ground (and if anything else is touching the ground, you should probably have that fixed). This means that ALL inputs depend DIRECTLY on your tires. Power, braking, and steering are all conditioned upon the amount of traction that your tires provide to you.
What Tires Should You Get?
So the next question is, What Tires to Get? Without getting into any specifics, the best thing to do is to pick a tire based on what you plan to do with your car. My Honda CRX is my daily driver, and it has the cheapest, nastiest 13 inch tires one can find. In fact, these were “found” on the car when I bought it, and I haven’t bothered to upgrade (though I did swap my Miata tires onto the CRX when I took it to the track). The reason is that these 13 inch tires do everything I need them to do as I tootle around town.
For my Miata, my tire needs are much more specific. I need tires that will give me maximum performance on the racetrack. So, I pretty much choose a tire from the highest “performance rating” category. I’ve tried a few different ones, and each has their pros and cons. The important thing though is that I get the right type of tire - maximum performance summer tire.
The Black Magic and Voodoo of Automobile Tires
And now we get to why I have selected this title: when you try to maximize your tire traction at the track, different brands and models of tires follow some general principles, but pretty much each march to their own beat.
It really boils down to the current technology used in making automobile tires. Tire is just a rubber compound with different grooves cut into it. And each of the different compounds used in each of the different tire models on the market today behaves differently in pretty much every aspect. These differences are compounded further by variations in tread design. Lets take a walk through some of the major areas:
