Road trip 2000 miles 4 people and luggage, tyre pressures to the max?

[Slips]

Got a long trip coming up in a couple of weeks with 4 people and boot full of luggage, just thinking I should raise the tyre pressures but the ride is hard on the normal pressures. Has anyone used the max load pressures and did the car still feel ok?

Thanks

I run max pressures all the time. As I often have people in the back.

Rides fine to me.

Upped the pressures and took it out for a drive, didn’t feel much different, just a little harder ride.

At moderate to high speeds, high tire pressures without higher load to compensate for them, won't just make for a harsher ride, it will also make the handling feel "floaty". It is indeed noticeable in an empty car. Fully loaded with passengers and luggage, it won't be. Just follow the directions in the owner's manual for setting PSI.

Handling felt fine over 1500 miles in one week, averaged 35.5 mpg on the 640 mile motorway run and 33 mpg for the total 1500 miles.
