Hola again, right got a staggered setup on my 3.0d sport 2004, 285/45 r19 rear and 255/50 r19 front, what options if any do I have in changing :

a.the alloys (ideally to a smaller SAME size all round)

b.the tire sizes to fit new alloys (ideally fat tires but within spec)

Just want to confirm what I can and cannot do? can I do what Freasder says below? and what the implications of going to smaller 17inch for example maybe with higher tire wall would mean for the x5?and if the sensors would pickup a problem as I have a self levelling rear axle according to the spec and that may sense the change and start to throw error codes???



Fraser in an old post on 'fat' tires said I could : The best you can do is fit 17s with anything from the stock 235/65s up to 265/70 in a ATR or MTR pattern
