A year or so ago, I got an old MTB (Ross Bryce Canyon) to leave at the in-laws up Maine. It came with some pretty fat tires, 2.1s (veloceraptors). Well, I finally got to take this thing out for a good spin today and besides needing a tune-up, I noticed that peddling this thing uphill. or on flat ground, on pavement or in the dirt, is like peddling through oatmeal! What are the general use for tires this wide, or was that just the fad back in the day when they made these things?
