Cost
Decrease
New rims and new tires are always an expensive investment, particularly since larger rim diameters are more expensive. Additionally, advanced materials and complicated tire construction methods are required to reduce tires height and increase their tread width. In turn, this causes the final product to be more expensive.
Weight
Increase
Generally, wheel weight is included in the overall weight of your vehicle. Cars that are lighter will be able to accelerate more easily and slow down more easily when necessary. They will also consume less fuel overall.
