Renault Grand Scenic Tyre Pressures - help

Hi

I am going on holiday to Europe tomorrow.



There will be 4 adults in the car and 4 bags much like what you are allowed on a plane and a collapsable wheelchair.



Question is, which of these tyre pressures should I use.



a. 4 people below 100mph Front 35psi Rear 33psi



or



b. 5 -7 people below 100mph Front 38psi Rear 38psi



I am assuming b., but would just like confirmation



Many thanks
