What to know before buying
Listing details to confirm
The listing identifies the material as Rubber, while its product description calls the tubes Butyl. The wheel-size and 47/622 details appear alongside a listed range of 47-622 to 62-622, and separate compatibility-width fields say 25 Millimeters minimum and 3 Millimeters maximum, which conflict with the stated 29 x 1.75–2.5 fit. Confirm the exact tube sizing and material for the selected listing before buying. Customer feedback also includes mixed durability reports, including a report of a tube failing at 40psi. Follow the tyre and tube manufacturers' pressure guidance.
