When most people are looking for a new set of car tyres, they often buy the cheapest set available at the time. However, the majority of drivers are smart enough to figure out that buying the least expensive tyres on the market probably isn’t a good idea in terms of longevity and safety.
A new tyre rating system originally introduced in 2012, forces buyers to take a closer look at the tyres they’re buying, for both their weaknesses and strengths. Overall, these new and stringent standards incorporated into the system makes at least one-third of all tyres that are now on the market outdated, most of them stemming from more generic brands.
Here are 5 key reasons why car tyres are so important to the general health of your vehicle.
1. Overall Safety
Long ago when tyres were once made of steel, they would roll down a smooth road forever, except for taking the corners. But, when manufacturers switched to rubber-based tyres, that all changed. Because tyres consist of extremely hard rubber, the rolling resistance is significantly lower. But, the grip is lower as well, making the distance for braking somewhat longer.
Virtually all tyre manufacturers face similar issues. The secret to achieving optimal fuel economy and grip balance lies in how the rubber is mixed, which involves using a substance known as carbon black that works to disperse heat away from the tyre as well as silica, a special hardening material that’s contained in glass.
2. Fuel Consumption
Experts believe that up to 20% of your vehicle’s overall fuel consumption is directly attributed to your tyres, which equals an entire tank of gas for every five times you fill up.
Tyres that have low-rolling resistance are becoming standard now on economy cars since the less a car’s engine has to work against tyre friction, the less fuel it will inevitably consume.
The concept of rolling resistance is primarily the result of a tyre continuously distorting and regaining its shape, producing heat and dispersing it in the form of lost energy. The key is to avoid this cycle as much as possible without affecting the integrity of the tyre.
3. Durability and Endurance
Economy tyres are virtually a waste of time and money since they never last. Many aspects affect the wear and tear of a tyre, especially the car’s weight, suspension geometry, and tyre pressure, which is why it’s crucial to regularly check your tyre pressure.
4. Rainy Weather
Rainy, wet weather greatly affects a car’s braking distance as well as how it grips the corners, which is precisely why a tyre’s tread pattern is so critical. It’s easy to understand why a car can skid more easily in rainy weather when you consider the fact that the contact area between the surface of the road and the tyre is only about 6 inches across.
5. Vehicle Tyre Ratings
The approach for rating tyres is based on a scale from A through G, where A is the best. Road noise, fuel efficiency, and wet weather grip are all graded separately, which enables customers to find the ideal tyre based on what they’re looking for. If a tyre doesn’t meet a certain standard, it’s automatically banned, which eliminates a number of more cheap, generic brands.
