Tyre sizes vary by year, trim and wheel option, and some XK8s run different sizes front and rear. Use your registration lookup, or check the sidewall and the vehicle placard/handbook before ordering.
You can, as long as the size and ratings are correct, but for balanced handling it is best to fit the same tyre model across an axle. If you replace just two tyres, fit the matching pair on the same axle.
Match the manufacturer specification for your XK8, and do not choose a lower speed rating or load index than required. If in doubt, use the registration search to see suitable rated options.
Most Jaguar XK8s were not designed for run-flat tyres as standard. Check your current sidewall markings and handbook; switching tyre type can change ride comfort and may affect what puncture solution you carry.
After choosing tyres, select a nearby fitting garage and an appointment slot. The tyres are delivered to that garage, and you attend the booking for fitting, balancing and disposal of your old tyres where included.
