I have a 2006 R1200 RT. My Beemer will soon need tires and I am looking for an alternate to the local BMW shop. Frankly, a little under $500 for two tires seems overpriced. Does anyone know of a shop that can change the tires if I bring them, the wheels and tires, into their shop? The local BMW shop will up-charge me $80, in labor charges if I buy the tires separately.
