Tyre & discs ware on a 360?

[Z8cookie]

Leading on from another topic… How much wear would you expect to have on your tyres & disc pads (all standard) per 2,000 miles?

Assuming we are talking 50% motorway 50% other roads & no track or ragging (honest!)

Also, What sort of life should you get from the exhaust before it starts spitting the white powder into the engine bay?

Any comments appreciated.
