Flat tire on the trainer

You can use a light coat of baby powder in inside the tire or any talcum powder It cuts done the friction inside the tire between the tube and tire. It cuts done the friction which of course cuts down the heat. Before you put the tube in sprinkle some in and slowly rotate the tire so the powder slides and coats the inside the tire then put tube in and inflate to desired pressure. Most flats i have had were caused by the rim tape at the spoke holes.
