It is strongly recommended to wear anti-puncture strips for extra protection. While the tubes are thicker, they are not indestructible. If a tip penetrates your tire, your inner tube can be pierced. Before installing, wrap the pointed end of the crowbar with a fiber cloth to prevent damage to the inner tire and coating of the hub.
When replacing a bike's inner tube, remember to add a bit of air before installation. This helps it take shape, preventing twisting or bunching that could lead to a pinch flat.
