This 2-pack of replacement inner tubes by PetrolScooter is designed for parents and caregivers looking to restore the smooth maneuverability of strollers, pushchairs, and buggies using 12.5x2 1/4 inch tires. Featuring a convenient straight Schrader valve, these tubes offer simple inflation at most standard air pumps, though users must verify their specific wheel diameter against the 195mm inner measurement before purchase to ensure a proper fit.

These are specifically designed for 12.5x2 1/4 inch tires. Please verify your current tire size printed on the sidewall before purchasing.
Yes, because they use a standard Schrader valve, most bicycle and automotive tire pumps will work.
No, the pack contains only the two inner tubes. You will need your own tire levers to remove the tire from the rim.
Check the inside of your tire casing thoroughly for thorns, wires, or sharp debris that may still be embedded in the rubber.
These are intended for standard pushchair and stroller speeds; they are not rated for bicycle or motorized vehicle high-speed usage.
Ensure the valve core is tightened securely and check that the tube was not pinched during the tire re-seating process.
Use dedicated tire levers and ensure the tube is slightly inflated before installation to give it shape and reduce the risk of pinching.
To install, remove the wheel from the stroller chassis and use tire levers to carefully pry the tire off the rim. Remove the damaged tube and inspect the inside of the tire casing for any thorns, glass, or debris that caused the original puncture. Insert the new tube, seating the valve through the rim hole, and gently work the tire bead back onto the rim. Ensure the tube is not pinched between the tire and the rim before inflating. To maintain the tubes, keep tires at the proper pressure to prevent 'pinch flats' and inspect them for debris after off-road use.
