Silly question perhaps but what would the benefit of a larger rear wheel be over the stock 17". I understand what happens with the front but not the rear (and presumably you'd need a speedo healer as well?)

Primarily more choice of tyres (as someone else said) - particularly knobblies...

I still don't have my maths head on, but a larger wheel will turn slower, so I imagine the (standard) over-reading speedo will actually be more accurate with the larger rear wheel?

Bigger wheel also give bigger contact area to the ground, and it also evens out small bumps more. (grammar alert)

Unfortunatly not. The wheel will still be spun at the same speed by the engine, but being larger in diameter you will move forwards faster which will throw the speedo out even more.

Think I'll be keeping to the 17" myself as it looks like I'm going to be keeping to more road going tyres :sunny:
