3 facts and 3 lies you never knew about tires

There’s plenty of information out there about tires – some true, some not so true, and some completely false. Today, we’ll tell you three facts and three lies about your tires, that you probably didn’t know!

3 facts and 3 lies you never knew about tires

Fact Number 1: Tires are naturally white!

When rubber tires were first invented for automobile applications in 1888, they were originally white – the natural colour of rubber. It wasn’t until the early 1900s, when it was found that the addition of carbon black in rubber manufacturing was able to significantly increase certain desirable qualities in the rubber used for tires.

The role of carbon black in tire manufacturing is that of a reinforcing filler – a substance which increases the durability and strength of the rubber. By adding 50% of carbon black to the total volume of rubber, the road-wear abrasion properties of the tire is increased 100 times, and the tensile strength of the tire is increased 10 times.

Did you know? Other materials such as silica and polymer are used nowadays to increase the strength of rubber, such as in the Bridgestone Turanza T005A which combines silica and polymer with Nano Pro-Tech™.


Fact Number 2: The era of the spare tire is ending.

Unlike cars of a decade ago, nearly one-third of new cars sold today do not come with a spare wheel. This is due to a variety of factors – less weight carried around, better fuel efficiency without a spare wheel, or space constraints in a car’s cargo area that prevent the application of a spare wheel.

Should your car come equipped without a spare wheel, you’ll typically find a puncture repair kit in the boot, which includes a bottle of sealant and an air pump. Alternatively, your car might be equipped with Run-Flat Technology (RFT) tires. In either case, they’re meant to be a temporary fix, so get the puncture permanently patched as soon as you can.

Did you know? RFT tires allow you to continue driving for a short distance, even after a puncture. Bridgestone’s RFT tires allow operation for up to 80km, at a maximum speed of 80km/h.


Fact Number 3: There are hundreds of materials in a single tire.

Despite looking rather simple, a tire is actually a complex combination of many materials, including elastomers such as both natural and synthetic rubber, metal reinforcements such as wires and bead wires, as well as textile reinforcements such as nylon and polyester.

All these materials contribute to the behaviour of the tire in a variety of situations, including daily demands of bearing 300 times its weight and functioning in blazing hot climates.

Did you know? As part of our continuous efforts to improve your experience, a new tread design was introduced on the Bridgestone Ecopia EP300 to provide longer lasting tires, allowing you to save the Earth while saving costs at the same time.


Lie Number 1: If you have your tire valve caps on, air will never escape.

Contrary to popular belief, tire valve caps are designed not to keep air in your tires, but to prevent foreign materials such as water droplets, dirt and dust particles from getting in. When the valve caps are missing, dirt may gather around the valve stem and get pushed into the tire during inflation.

Tire valve caps are most important when driving through puddles or on roads that are muddy and sandy, but considering how affordably priced tire valve caps are, they’re a cheap way to buy some peace of mind.


Lie Number 2: Slick tires make you go faster!

It’s true that racing slicks have more grip than conventional road tires, as the rubber compound used in racing slicks are specially designed to provide maximum grip at the track. However, they only work well in dry conditions and are NOT street legal. Due to their tread pattern, they are unable to dissipate water that gets trapped between the tire and the road, making them extremely dangerous in wet conditions.

For the best of both worlds, opt for tires such as the Bridgestone Potenza that offer a specially-developed tread compound for maximum grip, while featuring a tread pattern that provides effective drainage in wet conditions.


Lie Number 3: Your Tire Pressure Monitoring System (TPMS) can tell you when to get new tires.

The purpose of the Tire Pressure Monitoring System (TPMS) in your vehicle is to warn you that at least one or more of your tires are significantly under-inflated. The TPMS system is thus only able to keep track of the amount of pressure within a tire, and not the tread depth nor age of the tire.

To check your tires’ tread depth, use a tread depth gauge to make sure that there’s a minimum depth of 1.6mm. Alternatively, look out for the treadwear indicator bars between the tread ribs – if the tread is flush with the indicator bars, it’s time to get new tires!
