Mushroom-shaped plugs anchor from the inside of a tubeless tire rather than inserting rope-style material through the puncture. The Tubeless Pro Plugs from Lezyne use this design for home or workshop repairs that let you keep using a tire with remaining tread instead of replacing it. The mushroom head spreads across the interior surface while the stem fills the puncture hole, creating mechanical resistance in addition to the rubber cement bond.

The kit includes 3 plug sizes to match different puncture diameters. You get 2 plugs at 3mm, 2 at 3.5mm, and 2 at 4.5mm. Puncture size determines which plug diameter you'll need. The rubber cement bonds the plug material to the tire casing, and the abrasive pads roughen the interior surface before applying cement to improve adhesion. Two cement tubes are included for applying the adhesive.

Installation happens from inside the tire, which means you need to break the bead and remove the tire from the rim. This differs from trailside plug systems that insert from the outside and get you rolling again without tire removal. The Pro Plugs create permanent repairs for damaged tires you'd otherwise scrap, extending tire life when you've still got usable tread depth. If a tire takes a sidewall cut or large puncture during a ride and you plug it trailside to get home, these let you repair it properly afterward rather than retiring the tire.... Read More
