How Does a Wider Tire Affect Performance? Benefits and Drawbacks
When it comes to installing wider tires, such as 315 tires, on your vehicle, the first question that comes to mind is how a wider tire affects performance. The wider tires have certain benefits and drawbacks that may enhance or limit performance.
Benefits of wider tires
1. Improved Grip and Traction
The wider tires have a larger contact area with the road, which may increase traction and grip. It will increase the friction level between the road and the tire; ultimately, you will experience better traction on dry or wet terrain.
Due to enhanced friction, the braking distances were also reduced. Wider tires also improve cornering abilities by reducing slip during acceleration.
Due to such improved factors, driving safety and performance may be boosted by installing wider tires.
2. Improve Handling and Aesthetics
The wider tires ensure improved handling, allowing smoother maneuvering through the corners and increasing stability. You can enjoy a more engaging driving experience than before.
On the other hand, from an aesthetic standpoint, the wider tires look more aggressive and appealing than standard tires. They look awesome on sporty vehicles.
Drawbacks of wider tires
1. Reduce The Fuel Economy
As discussed earlier, wider tires create more friction than thinner tires, which may increase the load on the engine. Due to increased engine load, fuel efficiency may decrease.
Another factor that may decrease fuel efficiency and speed is the heavier weight. Wider tires are heavy. They also need larger rims that require more force for movement and may negatively impact the fuel economy.
2. Reduces Ride Comfort
Everyone enjoys smooth, quiet rides. The wider tires have lower sidewalls that may compromise ride comfort. They produce more noise and are more sensitive to road imperfections.
The wider tires have wider patches that may generate more noise at higher speeds than the thinner ones. So, your ride can be less comfortable after installing the wider tires.
