Hi, I have noticed for a while that my trainer bike continually gets flats when it just sits on the floor. It only seems to get flats while the bike is being used on the trainer, and after I patch it it rides perfectly fine outside. Is there any reason the bike gets flats indoors?

Cabin Fever?

tires tend to deflate over time.
It's diffusion of air from a higher concentration, inside the tube, to a lower concentration.

things that can accelerate deflation are small pin hole punctures in the tube, heat and use of CO2 cartridges instead of air from a pump.

Time for a new tube?
