But wouldn't inflating it before putting it in make it harder to put in?Baby Powder! Inflate the tube while it is out of the wheel and rub baby powder all over it. When you put it back in the tire it will keep it from sticking to the tire and help with no pinches. Also I use to double tube, which is taking a thin stocker tube and cutting it down the inside and baby powder it and wrap it around the heavy duty tube. This helps with punctures and pinches.
