I've just got a Boardman Hybrid Comp with the intention of doing cyclocross. There's plenty of clearance for wider tyres but I'm not sure of two things -

1. What sort of width tyre can fit on standard 700c road tyres?

2. What size is an ideal all round size tyre for a full season of cyclocross? I don't want to have to buy several sets to cover changing conditions.
