What are the tyre pressures on Double fives 255/55/18 and 245/45 /18.? Many thanks.

 

Label on passenger door opening?

Thanks for the reply, just had a look and the only labels are the jag spec label and airbag label,i can't find it anywhere on the car.

 

Armrest?

 

Thank you.

 

I have the 18” double nickels also. With every tire brand I’ve tried I’ve had the best and most uniform tire wear by going to a midpoint between the two factory suggested tire pressures:

my midpoints:
Front : 29 psi
Rear: 31 psi

Otherwise the high published pressure will result in classic signs of overinflation (wear in center of tread). And the low pressure gives accelerated tread wear.

All my XKs have that info under the console lid.

 

Ah yes, I forgot that we were talking about the X100 rather than the X150, so armrest rather than door.
