Quality as much as possible, aesthetics too. Although the fit to the rim too tight, without better equipment such as automatic machines for stretching rubbers on the rim can not do. With normal available tools you can get a good shattering of the rim.
The tire provides excellent handling and grip on any surface, and is relatively quiet. The tube added to the set surprised me with its weight ie that it is made of fairly thick rubber which will provide resistance to punctures.
