Low-profile tyres

The tyre section describes the ratio between height of a tyre to its width at the tread edge. The balloon tyre in the 1920s had a height-width ratio of about 1:1 compared to the low-profile tyres of today that can have a ratio of as low as 0.25:1.
Low-profile tyres are those where the ratio of the tyre's height to width is less than 80%.
