Where the rubber meets the road, a lot happens. The most expensive recurring expense that most car owners deal with is the cost of new tires. The average tire size and cost have increased dramatically as a result of the ongoing trend toward larger automobiles.

Being a knowledgeable consumer helps you save time and money while maintaining the functionality of your vehicle, crossover, SUV, or truck. In this regard, you can come to Flagstaff new tires shop to learn the fundamentals of tires and how to select new ones. However, this blog will provide you with some basic ideas.

The Parts of a Car Tire

Unexpectedly, tires include a lot more engineering than you might think. Here are the key components.

  • Tread

The majority of individuals are aware of this. The tread enables the tire to move water out of the way, release heat, and adapt to and grip the road surface. In the United States, depth is frequently expressed in 32nds. Despite variations in measures, most passenger car tires begin with between 9/32 and 10/32 of an inch of tread, and they last until between 2/32 and 3/32.

  • Sidewall

Between the tread and wheel rim on the side of the tire where reinforced rubber is present. The size and rigidity of this region will have a significant impact on the ride and handling qualities of the vehicle.

  • Bead

Where the tire meets the wheel and seals against it, there is a hard rubber core with a reinforced steel cable running through it. Modern tires have a bead that creates an airtight seal against the wheel, unlike earlier tires that had inner tubes (like bicycle tires).

  • Wear Indicators

These are thin elevated rubber bands that are parallel to the tread rows and run between them. The tire’s maker believes the tire has reached the end of its useful life and needs to be replaced when the tread wears down to the point where the individual tread blocks or rows are even with these indicator bars.

  • Internal Construction

Almost everyone is familiar with the term “steel-belted radial”. This is the most popular kind of tire made, and under the tread layer of the tire are braided steel belts that give the tire structural strength, puncture resistance, increased tire life, and traction. An inner layer of rubber that seals in the air is surrounded by crisscrossing plies of nylon or other materials to enhance strength.

How Can You Tell When to Change Your Tires?

The tread depth of a tire will have significantly decreased when it gets close to the end of its lifespan. This reduces the tire’s grip, which could result in you losing control of your car.

Due to a decrease in the thickness of the tread, the tire also becomes prone to punctures. Anyone can check to see whether a tire needs to be replaced because it is so straightforward. Most tires contain tread wear indicators, which are visible as rubber strips between tire grooves. The tire needs to be replaced when these are revealed.

Place a coin headfirst into the grooves on the tire’s surface if you can’t find the tread indicators. The tire is worn out if the top of the head is visible (less than 2/32 inches of tread depth).

Remember: Tire degradation is also influenced by age; typically, manufacturers advise replacing any tire that is more than ten years old. Get professional guidance from the retails shop of the new tires near Flagstaff and then start replacing your old tires.


For car owners, understanding the fundamentals of tires is essential especially when selecting new tires. Being a knowledgeable consumer will help you save money and guarantee the performance of your car despite the rising cost of tires owing to larger vehicles. Know the components that affect your ride, from the treads to the sidewalls. Maintaining safety and control involves keeping track of tread depth and age.
