Are Wheels Inspected as Standard?
Yes, without exception. The DVSA’s MOT Inspection Manual for private passenger and light commercial vehicles dedicates a full section to axles, wheels, tyres, and suspension. Only the wheels fitted to the vehicle at the time of inspection are assessed; spare wheels are excluded, though a tester may flag any defects they observe.
What the Tester Examines
The inspection covers both the structural condition of each wheel and the tyres mounted on them. The table below outlines the key checks and their potential outcomes:
| Area Inspected | Safety Concern | Possible MOT Outcome |
|---|---|---|
| Cracks or fractures in the wheel | Compromises structural integrity; risk of sudden failure | Dangerous fail |
| Buckles or rim distortion | Impairs steering precision and vehicle stability | Major or dangerous fail |
| Wheel fixings (studs and nuts) | Loose or missing fixings create an immediate hazard | Major fail |
| Tyre tread depth | Legal minimum is 1.6mm across the central three-quarters | Fail if below threshold |
| Tyre condition (cuts, bulges, exposed cords) | Risk of rapid deflation or blowout | Major or dangerous fail |
| Tyre-to-rim seating | Poor seal results in chronic pressure loss | Fail if compromised |
| Wheel bearing condition | Excessive play affects handling and component wear | Major fail |
Cracks: An Automatic Fail
A fractured wheel is among the most serious defects a tester can identify. Even a hairline crack undermines the load-bearing capacity of the rim and creates a pathway for slow air loss. Under repeated stress, the fracture will propagate — and if the wheel fails completely at speed, the consequences can be severe.
If a crack is present, it will result in a dangerous fail, and the vehicle must not leave under its own power. Do not drive to your MOT on a wheel you suspect is cracked. Our cracked wheel repair service uses specialist welding techniques and purpose-sourced materials to arrest crack propagation and restore structural integrity, backed by a 1-year warranty.

Buckles: More Serious Than They Appear
A buckled wheel — one that has been deformed by impact, typically from a pothole or kerb strike — is no longer geometrically true. This introduces vibration, compromises tyre contact with the road surface, and places additional stress on suspension and steering components over time.
Testers assess rim distortion visually and by rotating the wheel. Significant buckling that affects vehicle controllability will fail. Many drivers tolerate a persistent steering wheel vibration without identifying the cause; by the time it is flagged at an MOT, the damage to surrounding components may already be compounding. Our buckled wheel repair service restores wheels to factory geometry using hydraulic straightening equipment, with a 99% success rate.
Get Ahead of Your MOT
Identifying and resolving wheel damage before your test avoids a fail, a retest fee, and in the worst cases, a vehicle that cannot be driven home. Before booking your MOT, inspect each wheel for visible cracks around the spokes or inner barrel, flat spots or distortion along the rim edge, and any tyres that have been losing pressure without an obvious cause.
Our alloy wheel repairs team can assess the full condition of your wheels, advise on the most appropriate course of action, and get your car MOT-ready. For further guidance, visit our frequently asked questions page.
