Review on 🚲 Tannus Armour Tire Insert: The Ultimate Puncture Protection for Bike Tires by Ronald Orear

I used this on a new 3" 29" hardtail mountain bike converted to medium mount with the tire width increased from 2.25". There's barely enough clearance between the tire and the seatpost tube, but there's no friction or contact. Saved money buying cheap tires and got about 28psi pressure. Excellent traction and stability traversing the tree roots and rock trails of southern Pennsylvania's Pangea. Use steel tire levers and repair rim scratches for easy installation. Or break half of your plastic tire levers. Cutting this tire is not required.
