Wheel / Tyre dimensions

Hi

I have been trying to find some good mud tyres on the web for my Dad's discovery Series 2 and am having some trouble.

I have found several websites that ask for dimensions of the tyres, but I have no idea what they are! Can you please tell me what they are for our Disco?

Also do you know any website that sell good, cheap mud tyres?
