Hi There,

What would you guys suggest is the optimal tyre pressure for on road driving of a MY10 forester X with stock tyres and rims?

The placard on the car seem way too soft and spongey.

Cheers,
Brett

Stock Yoko running on 32PSI all around for a while (was basing it on the sticky thing on the driver door area) then 36PSI on the rear when I tow.

Then I had to run 36PSI all around because its uneven wear on my tyres I was told..

Maybe check out the sticky on your driver side door see what is the max when towing (even when you dont) and pump it up to that amount?

I usually run 36/34 F/R & bump rear up to 36 with the camper trailer which only has a towball download of about 50kg. If I'm doing extended dirt I drop to 30 all round.

it seems that 36/34 seems to be the consensus.

Has anyone noticed any significant fuel comsumption changes by increasing/decreasing the tyre pressure?

PSI - come on, we have been metric for 30 years!
kPa!!
What about the size of wheels? And I haven't seen a tyre pressure gauge yet that doesn't have PSI on it. Even the sticker on the car gives it in both forms.

the sticker on the my10 foz on the car is in kPa, thats why i reffered to it
I have 210 kpa all around, although nothing wrong with bumping it up to 220 kpa. I have done that before, no problems - u get a firmer ride. Although, I wonder how it goes especially with the very hot dry summers we have over here in Western Australia.

Maybe a dumb question but is this 34/36 range based on a warm tyre or is there no diff between hot and cold when checking the pressure?

Check when cold. The pressure should increase by 4 psi when warm; if less then the cold pressure is too high; if more then the cold pressure is too low.

Yep Metrics are brilliant & logical but some things just get processed in the brain as imperial.

34 all round.

Psi's

I just think my brain copes with remembering a smaller number easier- I run 34 on my 17" XT Adrenalins, little firm but seems best compromise.

Depends on the tyre type and loading.

36 for the Dueller 693 LTs; bumped up when loaded/towing the CT. Dropped by about a third for outback gibber and corrugated roads.

40 was recommended for the Dueller 697 LTs. Similar adjustments made for non-standard conditions.
