Has any one Fitted 285 75 R16's to an NM Pajero? If so what were the Issues?
I’ve had mine raised with OME Shocks and Springs and am currently Running 265 75 R16's but i want to go Bigger! I realize that the Fuel Econ will get a little worse but who cares. I'm More Interested to here about any possible Clashes or Rubbing in the Wheel Arches that sort of stuff. I'll post the Same Question on the Vic. Pajero Club Forum Too but I thought I'd try Here First.

Any comments appreciated.

Hi Matt,

i dont know about fitting them to pajero but they should look good, a friend was replacing his 275/70/16 on his cruiser (A/T's) and found that the 285/75/16 were about $20-$30 a tyre cheaper! no more convincing nesessary. You should have much difference in fuel economy because they are the same height, just a lil wider

anyway good luck

Steve

G'day Steve,
I could be wrong.......but my knowledge of tyre sizes is that a 285/75R16 is about 30mm larger diameter than a 265/75R16. As I understand it, the calculation is:
***First number is nominal tyre width in mm (so 285 is 20mm wider than a 265)
*** 2nd number is a percentage factor of the height of the tyre from tread level to the rim.
*** the 3rd number is the wheel diameter in bloody inches!!! (talk about mixing measurements!!! LOLOL)

So a 285/75R16's diamter is about 427.5mm + 16 inches
A 265/75R16's diameter is about 397.5mm + 16 inches.

30mm larger diameter. (Approx)

Nope your not wrong Roachie, your spot on. The 285 is 833mm the 265 is 806mm and the original 70 series are 760mm. So you have an overall increase in diameter of 73mm, that's pretty big, you are definately going to notice the affect in gearing, 4th gear will become 5th and you won't have much pull in 5th. To see if they'll foul on anything just have a look at the clearences you have now and you want at least 15mm to spare.

Well i guess i must be wrong.. i always assumed it was tyre width/profile measurement from the rim to outer tyre/rim size. 73mm is alot bigger, if you want to be sure matt before you do it just measure the height of your tyre and compare it to the height of the tyres your thinking of getting(the tyre guy should show u them before you choose the exact tyre). Remember- if your running difflocks (and presumably LSD) then make sure the spare tyre is the same size- if the spare is 73mm smaller then that could play havoc on your drivetrain - anyone feel free to correct me if im wrong

Anyway, let us know how u go

regards

steve
