Overview
What is the Kenda K50 14 x 2.125 tire built for?
The Kenda K50 Tire 14 x 2.125 Wire is built for replacing the worn-out factory tire on a kid's 14-inch BMX or pavement bike. The short knobby tread rolls fast on sidewalks and driveways while still grabbing dirt when the ride moves off pavement. A wire bead keeps the price low and the install simple for any mechanic with a pair of tire levers.
Sized at ISO 254 x 54mm with a 40 PSI max, the K50 fits standard 14-inch kids' rims and runs on a 22 TPI casing for durability over performance. Sidewall flat protection helps fend off the curbs and rough sidewalks that come with the territory. Best for parents, shops, and BMX riders who need a proven, no-nonsense 14-inch replacement tire.

FAQ
Good questions
Get to know Kenda

There's more to Kenda than this one product. Our Kenda page has the full Kenda lineup we carry and more about the brand.
Visit the Kenda page →Will this tire fit a standard 14-inch kids' bike?
Yes. The K50 uses the standard 14-inch BMX size (ISO 254) found on the vast majority of 14-inch kids' bikes. Check that your existing tire shows an ISO of 254 on the sidewall to confirm fitment.
What inner tube do I need for this tire?
A 14 x 1.75 to 14 x 2.125 inner tube with the correct valve type for your rim (Schrader is most common on kids' bikes). If you are not sure, check the size printed on your old tube or tire, or ask us.
What is the recommended tire pressure?
40 PSI is the maximum. For a lighter kid on smooth pavement, running 25 to 30 PSI gives a more comfortable ride. For heavier riders or rougher surfaces, run closer to the max to reduce the risk of pinch flats.
Does the K50 come as a pair or a single tire?
This listing is for one tire. If you are replacing both the front and rear, add two to your cart.
