XJS tyre pressure

[cml]

I've lost the bit of the manual with the tyre pressures in it. I may have asked this before (sorry) but - what is the tyre pressures for a '94 XJS 4.0?

I did a long run recently at 30psi and I think it might have been a bit soft for high speeds.

Should be 26F 28R up to 100 mph.

Weren't all Jag tyre pressures 26 front - 28 rear, for like 25 years or so.

XJ40, X300, X308 and XK (pre big wheels) Early S-Type.

[GavinPearson]

V12s have 28F, 28R.

Note this is for OE tyres, use 'non approved' tyres and the pressures have to rise to make sure the likelihood of failure diminishes.
