At Tyres.co.uk, Jaguar Sovereign tyre options include the Michelin Primacy 4+ and Goodyear Vector 4Seasons Gen-2 in 225/60 R16 102W XL for 1995-1997 X300 Sovereigns with standard 16-inch wheels. Earlier Sovereigns and different wheel choices use different fitments, so check the placard and registration prior to placing the order.
The Jaguar Sovereign X300 series from 1995 to 1997 place their tyre pressure and specification placard as well as load and speed rating and pressure metrics on the underside of the cubby box lid within the centre armrest. Earlier generations of Jaguar Sovereigns have differing placements, so refer to the handbook and original vehicle label.
Because the Jaguar Sovereign is rear-wheel drive, no model in this range has an all-wheel-drive counterpart. Where practicable, replace tyres in pairs on the same axle; if one axle receives a new tyre, UK safety recommendations advise that it be placed on the rear axle. Ensure that the tyres on each axle are of the same size, construction, and specifications, and that they are all compatible.
