Hi all. had my disco 3 for almost 2 years now and looking to change my 18" factory rubber (goodyear wranger HPs) for something that can bite in the mud - HOWEVER - I'm told by my local tyre place that the only replacement is a goodyear wranger HP!!!!!!. surely Coopers or someone is doing a replacement? Im hoping I dont have to run two sets of rims! Has anyone got a spare set of 17" D3 rims?
