just got a pair of 20" MWinters for my folding bike. due to the idiocy of the shop I bought them from, they arrived days later than necessary and on the eve of a huge snowstorm.

I could *really* use them, but the wrapper on the tires says they need to be "run in for approximately 25 miles on hard-top road to ensure spikes are permanently fixed."

Now that there's a layer of snow on the roads, I guess I pretty much can't use them until the snow melts ... in April? Or maybe I can go to a parking garage and do loops.

Any MWinter owners out there *not* break in the tires but not have problems with spikes/studs falling out? I am wanting to tempt fate here in Boston...
