Frequently asked questions
Quick answers about UK tyre fitment, MOT rules and seasonal options.
What do star/OEM markings mean on Jaguar XJ tyres?
Jaguar approves specific tyres for many of its models, marked with a star (BMW), MO (Mercedes), AO (Audi), J (Jaguar) or similar. OEM-marked tyres are tuned for that car's suspension and don't always come from the major brand-name fitter as a stock item — they may need to be ordered.
Are run-flat tyres needed on the 1968-1973 Jaguar XJ?
Most 1968-1973 Jaguar XJ cars were supplied with conventional tyres and a spare or repair kit. Only fit run-flats if your specific car was originally specified with them and has tyre pressure monitoring.
Are premium-brand tyres worth it on a Jaguar XJ?
On a Jaguar XJ, premium tyre brands (Michelin, Continental, Bridgestone, Pirelli, Goodyear) typically deliver longer tread life, better wet grip and quieter rolling. The cost difference is usually recouped over the tyre's life.
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.
What's different about the 1968-1973 XJ compared with other generations?
This is the 1968-1973 generation of the Jaguar XJ. Earlier and later generations use different platforms, wheel sizes and tyre fitments, so always match your specific year to the correct generation page.
