When you say 'green lanes', what type of surface are you riding? As you are asking the question I am assuming that your are at the begining of your learning ?

I ride with Eduro tyres on the lane bike, but I don't think I could live with them every day due to the noise and vibrations, although off tarmac they are brilliant!

If I were you I'd forget the wheel and tyre changing for now, and get some good dual purpose rubber - TCK's for example. Ample off tarmac grip and reasonable on tarmac grip.

Having two sets of wheels means, brake discs, chain set, bearings, pads and all the hassel in changing them. Changing tyres will quickly leave you rims marked and scuffed, even with rim protectors you'll see a change if you change them often. I'm not sure on the tyre beads, but I'm fairly confident that aren't made for multiple changes, and you don't want it to fail on the road.....

You soon get used to riding with knobblier rubber, it's realy not a problem - in fact my enduro tyres have better dry road grip than any of the dual purpose ones I've tried - although if I get 1000 miles out of a rear I'm doing bl00dy well!
