Q: How do you check for a slow leak in a tubeless tire?
A: Fill a spray bottle with a soapy water mixture. A small amount of dish detergent in water usually works well. Completely coat the tire by spraying the tread, the bead (the connection between the rubber tire and the rim), and the valve stem. A leak in the tire will start to blow little bubbles. Be sure to carefully check the valve stem and bead because they are common culprits for slow leaks.
