  • Tyre pressure for long, fully loaded, run.

    I'm off on an 800m round trip with a fully loaded car in a couple of hours...

    Any recommendations for tyre pressures?

    I normally run 35 all round but think I might increase to 36F and 38R for such a long laden run.

    Thoughts?

      theres usually a board with your recommended tyre preasure beside they air pumps .

      I just go by that , don't know if its correct or not

        whoops - forgot to say i've riding on the 19"s

        Theres plenty of discussion in the search that all points to 35 standard so I'm mainly interested in whether people would bump this up any for a 800m motorway ride with a full car?

            i can't help wonder if the official 35psi is too high - probably jacked up to improve fuel and CO2 scores for the brochures?

                          i think if you have it high when you leave then as the heat in your tyres increases with the miles then the pressure will increase aswell so if anything maybe drop the pressure a little

                              35psi on the rears is too high (I know what the book says but this IMO is a typo).

                              Try resetting the rears to 32psi (staying at 35psi on the fronts) - the improvement in handling is dramatic (the rear is way too skittish with the tyres at that 35psi).

                              Much more even wear at 32psi as well.

                              Fully loaded I'd go to 35ps at the rear.

                              For those running less than 35psi on the fronts - try 35psi and experience a sharper turn-in and less understeer. Steering is much better at the recommended pressure.

                              All IMO of course.
