Jagcat 12
Check out other posts in this section, eg "tyre bargain-too good to be true" etc.
I think the subject of tyres is pretty well covered.
Tyres for the convertible shouldn't be different from the coupe but they will vary by year/wheel/Sport/XJRS.
All puckah Pirellis are available but few tyre centres stock them - they must be ordered from Pirelli, usually 24 hour delivery. Later P6000's have a J suffix for Jaguar.
Don't let your local dealer persuade you that they are NOT available.....!
Expect to pay £100.00-ish per corner all in.
NB It's worth checking your owners handbook to ensure your current tyres are the correct ones for your car..........previous owners may have fitted "what was available"
