Are Wheel Spacers Legal in the UK?

Conditional

Wheel spacers are legal in the UK. No law bans them; the requirements are that the car stays safe, the wheels stay secure, and the tyres stay covered by the arches.

Why?

There is no UK regulation that prohibits wheel spacers, and no maximum spacer width written into law. The legal test is the outcome: the car must remain roadworthy, the wheels must be secure, and the tyres must not protrude beyond the bodywork.

Fitment quality is what decides that. Hub-centric spacers keep the wheel located on the hub rather than hanging on the bolts; bolts or studs must be long enough to keep full thread engagement; and everything must be torqued properly. At the MOT the tester checks wheel security and that nothing fouls the arches or suspension.

Insurers treat spacers as a modification, so declare them. And the common myth in reverse: spacers are not an automatic MOT failure - a properly fitted, non-protruding setup passes.

What decides if it's legal

  • No UK law bans wheel spacers.
  • Tyres must stay covered by the wheel arches at the top.
  • Use hub-centric spacers, the correct longer bolts/studs, and proper torque.
  • Wheels must not foul the arches or suspension at full lock and full compression.
  • Declare the modification to your insurer.

Does it depend on your car?

Arch clearance and factory offset decide how much spacer a car can take before the tyre reaches the bodyline, and that varies completely by model. Your car's page lists spacer kits confirmed to fit it.
