  • Off road tyre pressures

    Dear PSB dirty brains trust.

    I'm planning on riding a TTR250 down some sandy trails and onto a beach in the Great Southern today. What front and rear pressures would u recommend?

    So on the eight day, after wasting time faffing about with unimportant guff like heaven & earth & the waters & sky & creatures [& having a wee kip] & man.... God created PSB (GenesiSX-R1000)

    I usually run 14 in the front 18 in the rear. goes great on most surfaces. But if its totally sand going right down to 14 rear may help

        Anything much below 18 can spin on the rim, do you have beadlocks? If you do 10 to 15 will give you maximum traction. You can end up with sand in the bead at such low pressures
        Do you remember the good old days before the internet?

        when arguments were only entered into by the physically or intellectually able.

            I'd stick with 18+ on the rear then if it's really soft 15 in the front should give you good steering as long as you're not pulling stoppies

              15 is good front & rear with decent rimlocks.

              Can go down as low as 13 on MX retreads without fear of punctures.

                id go lower. i run about 15 front and rear on hard gravel. 12 will be okay in sand.

                  I'd go 18 18, keep the power up and your weight back maybe start off in 2nd to avoid the awkward change from 1st.

                    My sons 2010 TTR250 has rim locks both ends ..............


                    MX tyres are designed to be run between 10 and 16 PSI but without rim locks you will need to keep the rear pressure a bit higher.

                        Easy enough to check, just a nut and bolt on the centre of the rim between the spokes, usually opposite the valve. I probably threw him off calling it a beadlock I work on 4x4s more than trailbikes

                          15 psi all round and I drop it to 12 when in sand , if you run it that bit too high you will know because you will flog the arse out of the bike and still be trying to catch up , also you will sink in and it takes alot for the bike to pull up and out of the sand , on rocks if there up too much pressure you will find the bike smacks into them and you ping off them rather than floating over them which is what you want ,slip n slide too much is also a sign they are too high (say20 psi)

                          Regards dazz

                            Without making a new thread, what's a good pressure to run in my tyres on the road? I have road trail tyres.

                              My drz400 runs bridgestone ed03/ed04 and recommends 18psi but they're a majority off-road tyre design and compound on a relatively light bike. Check the maximum cold inflation pressure stamped on the sidewall and try 10% below, then test ride it to see if your tyres heat up and how it handles.
