Disco 4 wheels

morning - thanks for the add.
just bought a disco 4 with 20" wheels and now need 4 tyres....
was wondering whether its possible to downside to 19" as there appears to be much more choice (and less expense!!) with them. Can I fit disco 3 wheels without issue? Thank in advance

thanks in advance

You can fit 19” D3 wheels onto the D4, the D3 18’s won’t fit as the calipers on the rear are bigger on the D4.

thats really helpful - thanks
