rotating tyres on vehicles
I always buy (or request as part of the deal), and extra rim when getting a new car. I then have two spares and rotate them through from front to rear, rear to spare, and spare to front, every service.
The other thing I avoid is the problem of a spare that perhaps has more tread than the other tyres, and I reduce the possibility of having to replace all tyres if I stake one and have the problem of a new tyre being paired with worn tyres, which can play havoc with AWD electronics (and ultimately the diffs).. I don't know if the LR system is as sensitive as some systems, where their tolerances of tread depth difference across an axle is max of 5%.
Have found that most LR dealers have a supply of spare rims that they have as result of owners replacing with alternative rims, and they will sell you one at right price. That's my solution to the problem anyway. vbrab
