But they add an element of colour, especially with a dark wheel and tyre combination to highlight the size of the wheel in relation to the tyres, and they hide damage.
I would love to "stop hitting kerbs" especially after spending £1200 on a set of wheels, but when some van coming the other way forces you against the kerb to avoid a head on crash

its not just about being careless.....
