I started a thread on tyre pressures in the RC300h forum but this actually affects all of us, so hope I'm not transgressing Forum rules by restarting it here.
I asked the Forum: "In nearly all his 'advice' in the DT Honest John [HJ] advises ignoring manufacturer's recommended tyre pressures, e.g. 35/38 psi, and, unless we are doing 100 mph all the time, run on 30/30 (he says all his cars are on that). What do you say?"
This received many responses some supporting others saying go with the 'door pillar' pressures.
Yesterday I asked HJ to clarify his advice and received this reply: "As I incessantly point out, tyre pressures rise by up to 4PSI when the vehicle is used and the air inside the tyres heats up. Obviously if you set the cold pressures at 38PSI, the pressures could rise to 42PSI in use and that could result in a serious crash."
So, if I read him correctly, he is still saying 'ignore the manufacturer's recommendation (door pillar pressures when cold) and drop them down by 4 psi'?
