My C3 Aircross auto runs on 17 inch Bridgestone tyres.
I decided to check the tyre pressures as I thought they were a bit soft. The door pillar says 2.5 bar. Using my dial tyre pressure gauge they all registered 2.4 bar when cold, so I used my compressor to top them up to 2.5 bar. Not a lot some will say but in old money it's 1.5psi. after resetting the tyre pressure monitor I took the car for a run on A and B roads. The difference in the ride was significant. Smoother and quieter.

Yes I've noticed that 1.5 bar in the Bridgestone tyres makes a big difference.
As far as mpg goes we are now on E10 fuel which they say reduces mpg but I've noted my mpg on Mycitroen App is better.

As far as I am aware, although the pumps are marked E10, the ethanol content is a maximum of 10%. If E10 is produced in the refinery, it may be stored in tanks which are partially full of E5, reducing the ethanol content. When it goes to the petrol station it will be used to top up a tank with E5 in it, then you pump it into your car with E5 in the tank. So you actually don't know the ethanol content of your fuel. So speculation about fuel economy is a trather moot point.

Possible but the Sainsbury's that I use was shut yesterday as no fuel. They had petrol today and we're taking delivery if diesel as I filled up. Still I am going on a trip to Lincoln at the end if next week which should give a good indication of mpg. It will be the furthest I've driven since 2019.
