How do I choose the right tires for my Audi A1?

I'm not sure what type of tires are best for my Audi A1. Can someone give me some advice on how to choose the right tires?

The most important factor when choosing tires for your Audi A1 is the size. Be sure to check the tire size specified in your owner's manual or on the tire placard on your car's door frame. Your tires should be the same size as the original equipment. You can also opt for tires that are one or two sizes larger for better handling and performance.
