    What's the load index letter on the tyre and what max pressure has it got written?

      Hi Peter, try 34/36 psi to start and then use the 4/6psi rule. A bit of mucking around to get right but worth it as each veh/tyre combination is different and what works for one dosnt always work for another. Bob

      Forget the health food, I need all the preservatives I can get. Alcohol is a preservative isnt it?

        I run my STT's at 45-48psi hwy if you run in the 30's you just wear your edges of your tyres out and there is no issue with running them up higher pressures. I monitor them on my inner wise pressure monitors and there get to low 50's when driving long distances but around town is fine, save fuel too!

          To high a pressure results in increase tyre wear at the centre of the tread, therefore not getting the mileage out of the tyre and also reducing the tyre contact patch on the road which means that only half of the tyre is actually in contact with the road surface resulting in a less safer driving condition. To low a pressure results in the edges of the tyre bearing the full load of your driving, again, not really a safe option. Most people will agree that the tyre places often over inflate tyres and often give the wrong advice on tyre pressures for some reason of their own. Please do a search on this and other forums to get the real facts on correct tyre pressures.


          Sorry, rant over. Bob

            When on the 'black stuff' I run 38psi allround with my km2's. Have tried a few various pressures, ranging from 32 up to 42 & have found 38 to be best. 32 was too low in my opinion & anything above 42 is 'overkill' unless fully laden.

            On another note, when offroad, especially on shaley type surfaces dont go any higher than 20-22 or you will get some chipping....
