Hi Ford31,
Easy, use talcum or baby powder before installation. Put some powder in your hand and rub it on the tube. The tube is slightly tacky and some powder will stick to it.
Put some powder in the tire and rub the insides with your hands, it will also stick to the inside of the tire.
Fit the tire and tube as per normal.
Inflating the tube just a little, will make the rubbing as well as fitting the tube inside the tire, a easier.
