There is a grip loss, but the drop off in grip isn't a straight line.

You will see lots of disagreement on this point, but there is a
tendency towards center wear with elevated inflation pressure, but there are other factors that contribute more, so it is not always easy to see.

I'm kind of the odd man out here, but I don't think the increased inflation pressure is such a good idea. It also causes groove wander, harsh ride, and increased impact and puncture damage.

You will find many people for whom the increased fuel economy out weighs any other factor - and some will even deny that there are any negative issues.

Keep in mind that sometimes I'll carry up to 5 people + charge in the trunk (+350 kg)

Personally, I recommend no more than 5 psi (0.3 bar) above the pressure listed on the vehicle tire placard.
