I buy my tires at Southwestmototires.com and it only takes about five minutes to remove them. Then I have a local car tire place mount and balance them for $10.00 a piece. This saves me a ton of money because I usually go through 7 tires a season. Of course you have to be able to find a local guy that will do that for you but not a motorcycle shop, the local shops want $50 to mount and balance because I didn't buy them from them. If I had to have a BMW dealer do it I would have to travel at least 100 miles. So in the end I save a ton of money removing them and reinstalling my self at a total time of about ten minutes. Again the key for me is to just take in the rim tire and valve stem, car places wont remove them for you. Also for me the tire place is on the way to work so I drop off and pick up without any inconveinence.
