10 Things Every Gearhead Should Know About Car Tires

Car tires are arguably the most important exterior feature on any car, and they can make or break a sports car. Despite that, however, many owners don’t give them the attention they deserve or know anything about changing or fixing them.

Ever since the invention of the first pneumatic tire in 1888, tires have become major components of various vehicles, including cars, trucks, buses, aircraft, heavy equipment, and motorcycles. When it comes to cars, tires support the vehicle’s load, absorb road shocks, transmit braking and acceleration forces onto the road surface, as well as maintain and change the direction of travel.

The average person may not think about their car’s tires and wheels unless something goes wrong. However, tires can be a captivating topic of discussion, especially among gearheads. In this guide, we’ll walk you through some of the most interesting facts you probably don’t know about car tires.

10 Car Tires Are Naturally White

In the first 25 years of their existence, tires were white. This is because the rubber itself is white. The black color came as a result of added carbon black to enhance the durability and strength of tires. This was later substituted with Silica for most of the modern tire production. Still, black color has remained constant for appealing reasons such as the ability to withstand dirt and the color matching any color car.

9 Water In Tires Causes Pressure Changes

Between winter and summer, you can experience about 7 pounds per square inch (PSI) or more in pressure difference. Water, which typically enters in the form of humidity, is a bad thing to have inside a tire. Whether it’s in the form of liquid or vapor, water causes huge changes in pressure with changing temperatures than dry air does. Try filling your tires with nitrogen (usually denoted by green valve-stem cap). You’ll hardly find fluctuations since nitrogen doesn’t have water vapor in it, so pressure remains constant.


8 Run-flat Tires Can Work For A Limited Period Without Air

Run-flat tires have reinforced sidewalls that allow them to go without air inside the tire. Usually, they will run for approximately 100 miles after losing tire pressure. This eliminates the urgency of an immediate roadside repair.

However, once a run-flat tire gets punctured, it’s always advisable to replace instead of repairing it as the structural integrity is compromised.

Being one of the hardest natural substances on earth, walnut shells are used to make winter tires to enhance traction on slick roads. Crushed walnut shells embedded in the tire compound act like tiny spikes that dig into ice, adding traction, particularly during harsh winter driving conditions. Instead of simply “walnut” it’s better known as Microbit Technology in the manufacturing world.

Dubbed one of the most dramatic wheel inventions in the history of the industry, the glowing tires were made of synthetic rubber and translucent material with lights mounted on the inner rim. Then, the company dyed it various colors—blue, yellow, and bright green—to name a few.

These tires ended up being a prototype as the rubber was too expensive. On the flip side, various detractors made the fad fade somewhat hastier than Goodyear may have projected. For instance, the material used was very expensive for tire production. Tires also tended to melt upon applying brakes heavily and performed poorly in wet conditions.
