Tyres Feedback

Not many people seem to have given you a reply :o)

Don't have a patrol with 2.8, but a pajero with 2.8 diesel.
Depends on what size rubber you put on the 17" rims as to the resultant OD difference? Why not go up a size in tyre on the 15" rims? You running 31/10.5/15, or even 32/12/15?

I have same problem, does 2950 revs at 100k, and only getting about 10l/100k empty when trying hard for economy.

Have increased tyre size from 235/75/15 (29"od) to 235/86/16 (32"od on 16" nissan rims) and revs are now 2650 at 100k. Fuel consumption has dropped 5%, allowing for the 10% under reading of the speedo.
A GPS check shows it is actually 5% under reading.

But it is slower off the mark, and 5th doesn't hold hills as well, so you need to drive at the same throttle settings to see any difference in fuel economy. But on the flat and not too many hills, it has made a difference.

By my understanding of the law, you are not supposed to increase tyre OD more than 15mm, but I got mine blue plated as a modification.

Hope that helps.

i have thought about doing that because i am running 265 / 70 x 15 and thought about going to 32 / 11.5 x15. bfgs. My worry is i want tyres that i can easily get hold of in the ouback. Are 32 x 11.5 x 15 easy to get anywhere.
