|
|
This is a translated copy of the Table of in the back of my Mitsubishi Pajero book from 1996. It may help those people who ask on what basis is 30psi recommended. I know that some tyre manufacturers suggest higher pressures.
I don't know what the code after the tyre size is in the chart.
Code: |
Tyre Size Pressure kgf/cm2
Front Rear
215SR15 6PRLT 2.0 2.8
205/80R16 99Q 1.8 2.2
225/80R15 104S 1.8 2.0
265/70R15 110S 1.8 2.0
265/70R16 112S 1.8 2.0
31x10.5R15 6PRLT 2.0 2.0
215/85R18 113L LT 2.0 2.0
|
To convert kgf/cm2 to psi you multiply by 14.22 or to bar its by 0.9806.
So for psi figures are:
Code: |
Tyre Size Pressure PSI
Front Rear
215SR15 6PRLT 29 40
205/80R16 99Q 26 31
225/80R15 104S 26 29
265/70R15 110S 26 29
265/70R16 112S 26 29
31x10.5R15 6PRLT 29 29
215/85R18 113L LT 29 29
|
Hope that helps someone |

The code after the tyre size is the speed rating, the max speed you can go with that tyre |

I would like to go ahead and present my version of the right pressures for my 265 70 R15. In the manual for the GLS, they say also 1.8 at the front, 2.0 at the rear.
But tyre mechanics and other experienced travelers believe that you should actually go for approx 2.4 front, and 2.6 back, with the Desert Duelers.
I agree with that pressure, as at 1.8/2.0 the tyre becomes unstable in the middle, you wear down the sides, you are more prone to tipping in the corners, and it is easier to pop them out when on difficult maneuvres.
I would like to say I'm quite happy with them at a higher pressure, they wear very well, plenty of contact on the road, and rather comfortable all the same.
Tested in very rocky damaging terrain with no problems.
Maybe this should serve only the Desert Dueler users. Caveat emptor.
Cheers everyone! |

Sorry for silly question. Is this table relevant only for Mitsubishi models of that year? |

Hi,
My mk2 Shogun has 275/70 R 16 tyres (Silverstone AT-117 Special) fitted. Does anyone know what the PSI pressures would suit.
Many thanks. |

I have 30 psi in my 265/70 R16 General Grabber AT2's - have used this pressure for about 5 years with no uneven tyre wear. |

Ok thanks.
The 275/70 R 16 is slightly bigger than the 265/70 R 16 (sidewall height is +7mm, giving a +14mm overall height & +44mm overall diameter and is a +10mm wider) the only vehicles I can find that use the 275/70 R 16 as standard fitment are:
Brand Vehicle Engine Front pressure Rear pressure Front loaded Rear loaded
Toyota Land Cruiser 100 4.2 24 V TD 36 36 38 41
Toyota Land Cruiser 100 4.7 V 8 38 38 39 42
Toyota Land Cruiser 90 4.2 24 V TD 36 36 38 41
Toyota Land Cruiser 90 4.7 V 8 38 38 39 42
Do these pressures seem good for these tyres on my Shogun... I am guessing the Shogun and the Toyota Landcruiser both weigh about the same.
Cheers. |

Found a good site with tyre inflation info for 4 x 4s -- https://www.coopertires.com.au/media/1400/cooper-drivers-guide-tyre-pressures.pdf
I like the 4 psi rule:
THE “4 PSI” RULE
APPLIES TO BITUMEN ROAD USE ONLY
As a general rule, the following can be used - for road use
only: For passenger tyres, inflate your cold tyres to the
recommended tyre pressure on your vehicle’s tyre placard*.
Then to determine if you have the correct pressure for a given
load, note the cold pressure reading. Drive for at least 20-30
minutes to ensure they have reached operating temperature
and then check again. Ideally, they should be about 4psi above
the cold pressure. If the pressure is more than 4psi above the
cold pressure, you should add more air. That is because there
is too much friction, which builds up more heat than desirable.
Conversely, if they are less than 4psi above cold pressure, the
cold pressure is too high. Adjust your pressures accordingly.
For Light Truck and 4x4 tyres, use 6psi as a guide, but rough
and corrugated roads cause more flexing and your tyres may
rise more the 4 or 6psi. In which case applying this “rule” is not
recommended. |

Well, have been running around at 30 psi in all 4 tyres and all seems well |

Hi, New owner here, firstly thanks for all the info on the site, my shotgun warrior 3.2, came with Pirelli scorpions, 285/55/18 , can't find a pressure guide for them anywhere, any ideas guys, I know these aren't true off road tyres, but I'm an enthusiastic novice, so taking it slowly lol. |

How many years maximum one tire can be used and How many kilo-meters ? Apparently thread visibly looks okay... Please advise. |
