Frequently asked questions
Quick answers about UK tyre fitment, MOT rules and seasonal options.
Are tyres for the 1979-era Jaguar XJ still available?
Yes — common sizes for the 1979-1992 Jaguar XJ remain in production from major UK brands. Some classic-specific sizes may need a specialist supplier, especially for limited or sport variants.
What wet grip should I look for on the Jaguar XJ?

Are run-flat tyres needed on the 1979-1992 Jaguar XJ?

How long should tyres last on the 1979-1992 Jaguar XJ?
Typical UK tread life on the Jaguar XJ is around 20,000-40,000 miles depending on tyre brand, road conditions and driving style. Heavier trims tend to wear faster.
Where should I check the original tyre size for my Jaguar XJ?
Look in three places: (1) the sidewall of the existing tyre, (2) the placard inside the driver's door frame, and (3) the vehicle handbook. The driver's door placard is the official OEM specification, and the sidewall confirms what's fitted now.
