Why do some Audi A3 models have smaller wheels?

I noticed that some Audi A3 models have smaller wheels than others. What's the reason for this and does it have an effect on the car's performance or driving experience?

The size of wheels on a car can greatly affect its handling and overall performance. In the case of the Audi A3, the smaller wheels may have been chosen to enhance the car's agility and responsiveness on the road. The smaller size also means lighter weight, which can improve fuel efficiency and reduce braking distance.

Smaller wheels are often used on lower trim levels of a car to keep the cost of the vehicle down. In the case of the Audi A3, the smaller wheels may be used on the base model to appeal to budget-conscious buyers. However, this doesn't mean they are not functional or suitable for the car's performance.
