Performance
Result
Impact
Design
Worsen
Your car is visually less appealing with less prominent disks and narrow tires. If you care about the looks of your vehicle, think about the size of your disks.
Road holding ability
Worsen
Insufficient road grip. The degree of improvement in traction is largely determined by the aspect ratio of the wheel. In addition, reducing the width of the tires increases the braking distance on dry pavement. This happens because the tire-to-road contact area is reduced.
Precision of steering response
Worsen
The steering is slow and the cornering is poor. If your rim diameter is smaller and your tire height is higher, for example, you'll have reduced control of your vehicle while cornering and also decrease the speed you can safely take such turns.
Grip on dry pavement
Worsen
The contact patch of narrower tires is reduced, reducing traction on dry pavement.
Grip on wet pavement
Enhance
A narrower tire, which can expel more water from underneath the wheel, improves braking performance on wet pavement.
Grip on dirty surfaces
Enhance
Enhanced grip on muddy roads. When driving on sandy or dirty roads, less contact area is almost directly proportional to less braking distance.
Hydroplaning resistance
Enhance
Hydroplaning resistance has been improved. The contact area of the road surface is smaller when the tire is higher and narrower. The tread does not need to expel as much water from beneath the wheel.
Ride comfort and noise
Enhance
Comfortable riding. Traveling on tires with a higher profile is more comfortable than on tires with a lower profile. Noise levels are reduced. A reduction in tire width nearly always reduces tire noise, but it depends on the tread compound and shape of the tire. Because of the reduced travel distance between the tread blocks, air moves faster between them.
Fuel consumption
Decrease
Fuel consumption is significantly reduced. The rolling resistance of narrower tires is lower, which reduces fuel consumption.
Treadwear
Enhance
Reduced risk of tire and rim damage. The sides of tires with a higher profile are less likely to be damaged than those with a low profile.
Cost
Increase
Larger diameter wheels and low profile tires are more expensive than smaller diameter wheels and taller tires.
Weight
The same
