OK, just checked my tyre pressures after reading various opinions on what they should be (19" Adelaides, Bridgestone tyres). All were set at 42 psi, so I've reduced this to 38 psi all round as per the door sticker for partial loads. Tested it on a local section of bumpy road, and noticed an immediate improvement in ride quality. As a retired hydraulic engineer, I wouldn't have thought 3 psi would have amounted to much difference, but it has.
It’s surprising how much a few PSI alters the ride comfort.
A few years ago manufacturers twigged that setting up the car to run very high air pressure was another trick in their armoury to getting lower emissions under test conditions. I had one of the first 2019 BMW F40 M135i’s and those early models were set up to run silly high pressures and subsequently felt a bit skittish. Once dropped to around 38 psi they drove (and rode) significantly better.
I went from a couple of cars with standard reversing camera (GTI TCR, M135i) to a GTI Clubsport that didn’t have one and rarely missed the RVC. Very rarely. I’m now running a Golf with rear camera and although it’s handy it’s not £600 handy.
