In terms of safety, there may not be a more important component on your vehicle than its tires. Tires have evolved significantly since the earliest types, which were designed primarily for utility. Now, tires are made from specially formulated rubber compounds and the tread is engineered to provide specific safety features.

The First Tires

The earliest wheels were simply a solid curved piece of wood. As Continental Tires describes, “… leather was added to soften the ride. As time progressed it became solid rubber which led to today’s tire–the pneumatic, or air inflated, radial tire.”

Charles Goodyear is credited in the 1800’s with the discovery of the vulcanization process used to transform sticky raw rubber to firm pliable material which makes rubber a perfect material for tires. Tires were fabricated from solid vulcanized rubber until later in the century, when John Boyd Dunlop developed the popular pneumatic tire.

From that point, tire design gradually became more and more sophisticated with the development of bias ply tires and radial tires.

The Significance of Tire Tread

Tire tread is another important development in tire evolution. The tire tread is the part of the tire that actually meets the road. The elements of tire tread include tread blocks or tread lugs, tread grooves, tread voids, wear bar, and any extra features such as a rain grooves and siping. Tire tread spans the entire surface of the tire from shoulder to shoulder where the tread approaches the sidewall.

The areas between the tread blocks are referred to as the tread voids or tread grooves. Tread voids provide the tire with traction by enabling the tread blocks to move and flex as the tires to grip the road. They also allow the water to escape when roadways are wet. Tires with a high tread to void ratio provide better wet traction and braking ability.

Just as vehicles are engineered with a particular type of performance in mind, there are specific tread types and patterns that match each kind of intended performance. Tire tread is helps vehicles to corner tighter, accelerate more smoothly, and brake reliably. Tire tread is also capable of helping to maximize fuel economy.

Now that you know a little more about the importance of tire tread, you will understand why proper tire tread maintenance is so critical. In our next post, we will take a closer look at the best ways to maintain your tires and tire tread.

Does it seems like you have been seeing your tire pressure monitoring system light illuminating a little more frequently lately? If so, you can probably blame one simple reason – the cold.

In order to understand how cold effects your TPMS, it is necessary to how your TPMS works. The system use sensors technology to alert drivers when tire pressure in one of the tires goes below a predetermined level. When tire pressure in one or more of your tires drops, the light comes on.

Since ambient air pressure decreases in frigid temperatures, the air pressure in a tire goes down 1-2 pounds for every 10 degrees of temperature change. This is why drivers typically see the TPMS light illuminate more frequently.

It is important to check your tire pressure when the tires are cold. Why? Once you hit the road, friction will cause the tires to heat up, increasing the pressure within the tire. Checking the tire pressure after you have been driving awhile may give an inaccurately high pressure reading.

Proper tire inflation is always important, but it is especially critical in the cold winter months when weather conditions make driving more hazardous. Tire pressure is important because:

• Low tire pressure can make a vehicle handle poorly
• Tires tend to wear out much faster when they are not properly inflated
• Under inflated tires tend to overheat, which could lead to a blowout
• Low tire pressure reduces gas mileage and costs you money

Check the pressure of your tires monthly. In order to obtain the most accurate pressure level, wait until tires have cooled – about 30 minutes after parking – or check the pressure first thing in the morning.
