Is your trainer lined with barbed wire?

Buy one - its worth it. I personally use the Continental one (orange). I used an old Gatorskin at first, and after about 30 mins of riding, there was black dust all over the place and the tire was very, very hot. I switched to the trainer tire and after over 1000kms of hard interval riding, its still fine with no sign of wear.

I have it mounted on a dedicated rim and cassette which makes switching between the trainer and the road very easy.
