Yes, a cracked alloy wheel can fail an MOT in Timperley if the damage affects the structural integrity of the wheel or poses a safety risk. MOT testers assess wheels for cracks, distortion, and serious damage that could compromise safe driving. Minor cosmetic marks will not cause a failure, but structural cracks usually will.
If you suspect a cracked alloy, it is important to have it inspected before your MOT test.
Why This Happens or What You Need to Know
Alloy wheels can crack due to impact damage. Common causes include:
- Potholes
- Kerb strikes
- Uneven road surfaces
- Sudden heavy impacts
- Driving on low tyre pressure
Cracks often develop:
- Along the inner barrel
- Around the spokes
- Near the tyre bead seat
- After repeated stress or previous repairs
Some cracks are visible from the outside. Others are hidden on the inner face of the wheel and only discovered when the tyre is removed.
During an MOT, the tester checks that wheels are free from serious defects. According to GOV.UK MOT inspection standards, wheels must not be cracked or insecure if this would affect the safety of the vehicle.
If a crack compromises strength or stability, it is likely to result in a failure.
Will All Cracks Automatically Fail an MOT?
Not every mark or hairline imperfection leads to an immediate failure.
However, an MOT tester will fail a vehicle if:
- The crack weakens the wheel structure
- There is evidence of instability
- The damage could cause tyre pressure loss
- The wheel is likely to deteriorate further
Very small surface fractures may require professional assessment to determine severity. What appears minor externally may extend deeper into the metal.
That is why proper inspection at a specialist workshop in Timperley is recommended before booking an MOT if you suspect damage.
What Should You Do If You Have a Cracked Alloy Wheel?
If you discover a crack before your MOT:
- Avoid long-distance driving
- Do not ignore slow air loss
- Have the wheel removed and inspected properly
- Confirm whether safe repair is possible
Minor cracks in non-critical areas can sometimes be repaired using specialist welding techniques. However, cracks in high-stress areas such as spokes or load-bearing sections may require replacement.
Driving on a cracked alloy wheel is risky. Even a small fracture can spread under braking forces or further impact.
Repair or Replace Before Your MOT?
Repair may be suitable if:
- The crack is minor
- It is located in a non-structural area
- Professional inspection confirms safety
- The wheel has not been weakened by previous machining
Replacement may be safer if:
- The crack runs through a spoke
- Structural strength is compromised
- The wheel has multiple previous repairs
- The damage continues to spread
An inspection ensures you are not replacing a wheel unnecessarily, but also not risking an MOT failure or safety issue.
