I have always run 2 sets of rims and tires for winter/summer, it keeps the bead healthy and makes changing them over really easy. The only downside is that they are heavy when putting them in storage (garage attic). On my old LR3, I actually used a set of BMW X5 Rims as winters, the bolt pattern lined right up but I needed new lug nuts.
Does anybody know the exact spacing required if I wanted to use my old 18" 10 spoke rims from my LR3 on my 2015 LR4. Everybody seems to think that they will clear the brakes but will need spacers... unfortunately I can't find the spacing requirement to get them back to the stock clearance.
