Jaguar S-type which can only have one type of tyre

[Rpmayne 0]

Was chatting to a mate at work because he was looking at changing his tyres on a Jaguar S-type 4.0V8. He had Pirelli P6000 (225 55 R16), so I naturally said throw them away and get something decent. Thing is, apparently Jaguar worked with Pirelli to develop the P6000 'J' tyre which is only specific to this car because the normal one had a unsufficiently strong side wall for this car. The manufacturer has now said that he can't fit anything else or the insurance / warranty is invalid.

 

I personally can't believe that an apparently uprated P6000 is the only tyre that can run on this car. Surely it's not that special. Sounds more like a stitch up between Jag and Pirelli to me.

 

Anyone heard of this sort of thing before?
