Before you come in for a service, you can learn a few things about the components of a tire. These components of a tire include the bead, body ply, inner liner and sidewall. It is important to understand what each of them do in order to maximize safety and performance. Read on to learn about these components. Once you know what they are, you’ll be able to determine which type of tire is right for you at the best tire center Tacoma, WA.


A tire consists of a casing of rubber and metallic strands of beads embedded in it. The beads are preferably oriented in a round cross-section. In addition, they are designed to overlap each other by the same amount, which is between seven and twelve centimeters for passenger tire sizes.

A tire has many different layers, but it only uses a few of them. The inner layers are called beading. This is an important part of the tire because it allows air to circulate more easily. In addition, the beading material must be very flexible. Moreover, it must be able to withstand the weight of the vehicle that is riding on it.

The beading can lose strength with wear, age and neglect. If you are concerned about the health of your tires, check us out at the best tire center Tacoma, WA has to offer!

Body Ply

The body ply of a tire is composed of textile cords that are processed by a variety of techniques. The textile strips are made of transverse yarns that have minimum tensile strength. The transverse yarns’ primary purpose is to maintain the proper spacing between the cords during processing.

The process of making a tire’s body ply involves many operations. Each type of tire requires a different type of coated composite strip. The composite strip has a special structure, which can present several problems. One of the main drawbacks is the increased risk of unwanted vibration in the finished tire. Another potential problem is the proximity of the transverse splices to the drum splice.

A tire’s body ply, also known as the carcass ply, extends from the bead area to the crown portion of the tire. It typically consists of a number of layers of cords that are oriented at more than 80 degrees from the equatorial plane. These layers help to keep the tire’s inflation pressure consistent and determine the overall shape of the tire upon inflation.

Inner Liner

The inner liner of a tire is composed of a rubber composition that can include various additives. The rubber composition may include process oil, vegetable oil, or fat. Some of the oil additives used in the manufacturing of inner liners include cotton seed oil, linseed oil, rapeseed oil and palm oil. Other additives used in the manufacturing of tire liners include coconut oil, peanut oil and pine tar.

The inner liner of a tire should be thick enough to prevent pressure loss. Thinner liners allow moisture or compressed air to escape, reducing the pressure inside the tire. Thinner liners may also have insufficient chemical compounds. Check the placard of your vehicle to find out if your tire has an inner liner that meets the specifications of the manufacturer.

If the inner liner is not strong enough to prevent tire pressure from escaping, it can lead to tire blowouts. While these can be repaired, they can cause a tire to lose pressure. Stop by the best tire center Tacoma has – Courtesy Auto and Tire of Tacoma – to get your tire checked out and you back on the road safely.

If you want to check your tire pressure, you can stop by our shop, stop by most gas stations to use their meter or order you own tire pressure gauge on Amazon to use at your convenience.

If you’ve noticed cracks in the sidewall of your tire, you may need to replace it. You will definitely want to stop by the best tire center Tacoma, WA has to offer – Courtesy Auto and Tire. These cracks can increase in length, depth and number over time. These cracks can affect the overall performance of the tire and can lead to the failure of the tire. You should inspect your tire at least once a year to check for sidewall damage and get it repaired before it gets worse.

Most tire sidewalls consist of two corded rubber ply. However, some performance tires and some truck tires may have three or four. While there’s no standard number of plies, the stronger the sidewall, the higher the rating. For example, light truck tires often have Load Range C or higher ratings and are best suited for towing.

In addition to the tread and bead, the sidewalls have cord reinforcements inside to absorb energy derived from irregularities in the road. The pressurized air within the tire also helps with this job. Run-flat and on-flat tires typically have strong sidewalls, which help prevent the tire from buckling under pressure. This also gives them a stiffer ride. Some sidewalls contain decorative elements as well.
