“It’s a compromise between ‘comfort’ ride and safety and handling. Advance driving course will add around 8psi cold. I find on any rim size additional 4psi makes a difference. Why ? Under heavy braking the tyre collapsed in the middle, by running higher inflation the complete width of the type is on the road, better braking efficiency - if under inflated only the outer edges keep in contact with the ground, causing less efficiency and longer distance to stop. Higher inflation also ensures tyre does not warp and twist on rim when turning. Too much inflation is just as bad, only the middle touches road - less braking efficiency and wear out tyre quicker. OEM recommended pressure is for comfort and sometimes sees increased edge wear over life of tyre. Regular tyre rotation and wheel balance and alignment will maximise tyre life. Try for yourself, But I have found around 4psi extra when cold is optimum.”
