What is a Wheel Rim?

The metal or carbon hoop the tyre sits on and the spokes pull against.

TYRE · RIM · SPOKES · HUB

Simplified schematic — not to scale.

In plain English

The rim is the circular structure the tyre wraps around. Spokes pull inward from the hub to keep it perfectly round and true under load.

A simple analogy

It's a drum skin held taut by dozens of tiny tuning pegs — the spokes.

How it works

Each spoke's tension pulls the rim into shape from a different angle. Get all the tensions balanced and the wheel spins true; let one go slack and it starts to wobble.

Signs of trouble

  • Wobble or wave when spinning the wheel
  • Visible dents or flat spots
  • A worn braking track groove on rim-brake wheels
Rough UK cost
