Tire Capacity Guide

A 250ml bottle is highly economical, holding enough liquid to completely set up or top up multiple tires:

• Mountain Bike Tires (29" / 27.5"): Seals approximately 2 to 3 tires (requires ~80ml–120ml per tire).
• Gravel & Road Bike Tires: Seals approximately 3 to 4 tires (requires ~60ml–90ml per tire).
