Enhanced design. The visual appearance of your car is usually improved by wider rims and wider tires.
Road holding ability
Improved traction. Wheel aspect ratio plays a critical role in determining the degree of traction.
Increasing the width of your tires also reduces braking distance on dry pavement due to the increased area of contact
between the tire and the road surface. The larger rim diameter allows for larger car brake discs and calipers with more pistons.
These additions enhance the effectiveness of a car's braking system significantly.
Precision of steering response
Grip on dry pavement
In dry conditions, wide tires increase the contact patch and increase traction.
Grip on wet pavement
On wet pavement, wider tires make braking less effective because they cannot expel the water from under the wheel as effectively as narrow tires.
Grip on dirty surfaces
On muddy roads, the grip is reduced. When it comes to sandy or slippery roads, the increase in the contact area
is almost directly proportional to the increase in braking distance.
Hydroplaning resistance is reduced. Tires with a lower and wider profile create a larger contact area with the road surface.
The tread needs to expel more water from underneath the wheel as a result. It is for this reason that tire manufacturers
use directional treads or, as has become increasingly common, asymmetric treads, in which the two halves of the tread
can be designed independently of one another.
Ride comfort and noise
The ride is uncomfortable. Tires with a lower profile make travel less comfortable than tires with a higher profile.
The result is increased noise. Increasing the width of a tire almost always increases the noise, depending on the tread
compound and the tire shape. There is an increased travel distance between the tread blocks because air moves between them.
A higher fuel consumption. Fuel consumption is increased by wider tires due to their higher rolling resistance.
