Had my 2016 F pace for 6 months and delighted with it so far hitting almost 50mpg on long gentle runs. That's by the way. Normally, only my wife and I are in the car but soon I will be taking a full load with luggage on a longish trip. Looking at the tyre pressure plate on the car I am bemused as none of the tyres on the car seem to fit the description on the plate. They are all 255/60 R18. The rear ones are '112H' and the front 108W. Any advice would be appreciated.
