Is there really a differance? I ride a tire in the winter.....is it not good in the summer....is there really that much more CRAP on the rodes in the winter?

Training wheels? Now days.....do people really use them that much? Now days wheels are strong and light....and maybe have powertaps in them....do people really have 2 sets of wheels to ride on? I have a backup set of wheels BUT I hate riding them.....I would rather ride my good wheels...

If you live in an area that has a distinct winter season, it sucks to flat 80km from home in the cold. This is a recipe for getting sick. You're wet and standing in the cold for 10 minutes while you change your flat.

In winter using a heavier more puncture and cut resistant tire makes sense.

Keeping your race wheels tight and straight makes it feel like you have a rocket up your butt when you take off those heavy, but very reliable, training wheels and slide on your, oh so special, I'm gonna kick butt and take names, wheelset.

Makes my legs feel like they have some extra snap.

In fact, my team uses 3 different sets of racing wheels, all for different conditions, along with our training wheels.

You should have on wheel for your trainer with a trainer tire. Wheelset for training with trainertires (gatorskins, krylion carbons ect), and your race wheels should have something like pro race 2s unless you run tubulars. I don't race but this is what I gather from reading BF too much.

Wheels are like shoes. Chicks dig them, they are expensive, but there is always room for another pair.

Just like Bob Dopolina said, there is more debris, gravel, sand, rocksalt, and other stuff that is rough on tires. The extra weight of true training tires will only boost the cardiovascular effect.
It will decrease the likelihood of making an unplanned repair on the side of the road, fingers freezing, and watching as the sun begins to set.
