For me the answer is no. In the last 5 years and 3 BMWs I have had one tire replaced due to a nail that would have covered.
In my 335 and Z4 I go through a set of tires in 1.5 years or 20k miles so tire expense is a consideration but since they don't offer wear replacement the cost is not worth it. We also have pretty good roads in S FL so I don't have to worry about pot holes and such.
