This is a replied received after Marc’s letter published in November 2007 MPN
I read with interest Marcus Miller’s letter in November’s  MPN. I understand his position, and if it works for him, that’s great. We used to mount tires purchase elsewhere until we put one on a large touring bike, and the client incurred a severe speed wobble and had a mild crash as a result. We checked the tire, and all seemed well until we test rode the bike, and no matter what we did, the speed wobble, in some conditions, was very evident even though all was well with the bike. This was the well maintained unit of a very experienced rider who had never had a problem before. Upon further investigation, we discovered that the tire was a “factory blem,” something not told to the client. We replaced the tire with one of ours, and he hasn’t had a problem since. At that point, we decided that we were never going to install another tire from another seller, unless there was an unusual circumstance, and we could verify the tire’s provenance. Yes, you may have a customer angry with you if you refuse to install his tire from elsewhere, but I don’t need these kinds of hassles, and I’m sure other dealers don’t either. We have found that if we explain our position properly most people understand. Unfortunately, in this age of using the courts as a lottery, you have to watch out for yourself, because no one else will.
