Bike Tires & Wheels

Tires and wheels are where most roadside failures happen, and they are also the part of the bike most people can learn to fix completely. A puncture that strands a beginner is a ten-minute job for someone who has done it three times.

These guides cover the whole sequence: getting a wheel out, getting a tire off without levering it to death, finding what actually caused the flat, and putting everything back so it holds air. Tubeless setups and buckled rims are here too.

What you'll learn

  • Get a wheel off and back on, front or rear, without fighting the derailleur
  • Change a tire or tube properly, including the bead work that avoids pinch flats
  • Find the cause of a puncture instead of fitting a new tube into the same nail
  • Patch a tube so the repair is permanent rather than temporary
  • Diagnose and repair a tubeless setup that will not seal
  • True a wheel with a lateral wobble using nothing more than brake pads as a gauge

Common questions

Why does my bike tire keep going flat?

Almost always because the cause is still embedded in the tire, the rim tape has slipped, or you are running too little pressure. Check all three before blaming the tubes.

How often should I replace bike tires?

By condition rather than by date: cuts through the casing, visible casing threads, cracking sidewalls or a squared-off profile all mean replacement. Mileage varies enormously with tire and surface.

Do I need tire levers?

For fitting, ideally not — levers are the main cause of pinched tubes. For removal, one or two are usually necessary. Three means you are levering rather than pushing the bead into the rim channel.
