Tyre presure (255/70/15) sportrak

Forum: 

Hi ive bought a 90 sportrak with 255/70/15 BF Goodrich tyres.
I was wondering what presure to run them at.

Thanks SR.

Try a tyre-maker's website.

Sorry I can't give you the answer, but the inflation pressure of tyres depends on the size of the tyre and the weight you are asking it to bear.

These are big tyres for your vehicle, so I guess that the pressure will need to be reduced compared with that for the normal size. The amount of reduction I don't know, but I would guess that some manufacturers websites should have a calculator to work it out.

hi m8 my fourtrak has the same size of tyre thair front 29 psi and rear 26 psi try and reduce it 2or 3 psi to around say 25 front 23 rear for road work down to 15 off road

255/70r15 tyre pressure

jap import fourtrak (1990) standard fitment tyres 255/70r15 because it says so on the door pillar when you open the door reads 1.8 bar(26psi) all round. hope that helps someone. Wally
