Frequently Asked Questions(FAQ)

Are 315 Tires Similar To 35-Inch Tires?

Yes, 315 tires are equivalent to 35-inch tires. However, 315 is the tread width in millimeters, while 35 is the tire diameter in inches. The approved comparable size for a standard 35-inch tire is 315/70/17.

What Are Wide Tires?

The size and width of the tires influence how the automobile behaves in various conditions and, in most cases, gives the best overall performance. By comparison, a wide tire is a tire that is larger than a standard tire.

Why Would You Want To Switch To Wider Tires?

If your car’s specifications allow it, you can go from narrower to wider tires for various reasons, ranging from improved aesthetics to improved performance. Wide tires, for example, can grip and accelerate on dry surfaces significantly better than narrow tires because their contact area is more significant. They’re also ideal for specific applications, such as winter driving.

What Are The Possible Negative Effects of Using Wide Tires?

Fitting your wheels with wide tires is a risk if you ignore the car or tire manufacturer’s guidelines. The tires, for example, may be more prone to hydroplaning or aquaplaning. Also, your car will have less control over slick, loose surfaces like gravel.

Moreover, a wide tire might not fit properly within the wheel. It may protrude outwards. As a result, you’ll have less flexibility of motion and a smaller turning radius. Last but not least, road noise will increase, reducing the comfort of your ride.

What Are the Advantages of Using Wider Tires in Winter?

There are numerous benefits to fitting your wheels with wide tires over the conventional narrow tires throughout the winter season. Some of these advantages are listed below:

  • They offer drivability that is steady and balanced and enhanced steering precision.
  • Due to their substantial tread blocks, the braking distance is reduced.
  • Even on snow, more spies interlock with the ground.
  • They provide a more sporty driving comfort

What Happens When Your Tire Size Is Increased?

Increased overall tire diameter affects your vehicle’s handling, increases braking distance, increases fuel consumption, and causes your car’s speedometer to read slower than it should.

Are Lighter Weight Tires Preferable to Heavier Ones?

Both tires may be worse or better, depending on various conditions. For example, lighter tires are frequently easier to change and install. On the other hand, heavier tires can bear more weight than lighter tires.
