A quick question regarding tyre pressures, when I brought the car 6 months ago I decided to fit 4 Michelin primary 4’s which have been amazing but seem to be noisy at the correct psi of 36 so as a nerd I raised the pressure to 38 and found them to be much better.

 

have any of you experienced the same sort of thing?

No specific experience of this on a Superb, but I have found a lot of VAG cars specify a lower PSI than what I'd personally run at.
