Find Tyres for Hennessey

Frequently asked questions

Quick answers about UK tyre fitment, MOT rules and seasonal options.

• What's the most common UK Hennessey tyre size?

  Common Hennessey sizes vary by model and trim. Mid-range variants often use sizes around 205/55 R16, 225/45 R17 or 225/40 R18. Always confirm against the sidewall and door placard of your specific car.

• Why do my Hennessey tyres wear unevenly?

  Uneven wear on a Hennessey usually points to incorrect alignment, suspension wear, under- or over-inflation, or tracking knocked off by a pothole. A four-wheel alignment check is the first step.

• Are Hennessey OEM-marked tyres different from standard ones?

  Hennessey works with tyre makers to develop OEM-marked versions tuned for specific models — typically with adjusted compound and structure. OEM markings (e.g. star, MO, AO) match the car's suspension calibration but aren't always the cheapest replacement option.

• Do I have to use Hennessey-approved tyres?

  Approved tyres are recommended for performance and warranty consistency, but UK law and MOT only require tyres that match the original size, load index and speed rating. Many drivers use major-brand non-approved tyres successfully.

• What's the legal tread depth for a Hennessey in the UK?

  1.6mm across the central three-quarters of the tyre, around the full circumference. Many tyre safety bodies recommend replacing earlier — at around 3mm — to keep wet braking distances within safer limits.
