just upgraded ( I think? ) from 97 disco 1 300tdi ES to a 99 disco 2 td5 ES. It is currently sat on 255/65/r16's on steel rims with a slightly deeper offset ( than normal ). Now although I like the look of the stance I don't like the look of the centres, as in able to see hubs & standing proud wheel nuts. So I have bought a set of alloys ( no tyres ) which are 7 1/2 J18" so with standard height suspension & body what size tyre would usually go on 18" rims on a disco 2 ?
