I,m running 245/75/16 bfg's and they are fine. I did try 265's and they felt too sluggish when I was loaded. The 245 have been good on and offroad and has put the speedo correct. I would imagine it puts the gear ratio similar to those with the 3.9 diffs running 265's.

From the Brochure (added Challenger and Hilux for kicks) and to see if any of the bits are interchangeable.
(Note- I did not include all different combinations- just the ones I thought would be most common)
Drive Train Specs. (click on pics to get full sized)
Interesting data- the petrol has a larger alternator than the diesel.
Petrol also gets 4.3 diff gears
Petrol is discontinued in the MN Triton
The standard tyre size on the triton is 29.5" (0.5" above the hilus standard) and the challenger with the same running gear as the MN triton is around 30.5". As you are aware increasing tyre sizes affects gearing and because the Triton has a 1:1 straight through configuration in the transfer case, this cannot be changed so let's look at the the theoretical Diff ratio required so that the drive train is returned the stock specification. This varies based on the stock diff ratios from the table above.
Ratios required to run larger tyres
this shows- poorly represented- see the required ratio column, that for the ML triton diesel (with 4.1 final ratio) that it requires 4.4 diff ratio when running on 32" tyres- nearest stock ratio is the petrols 4.3
The MN to return to stock because of the standard diff ratio of 3.9 would require 4.2 (nearest is the ML tritons 4.1 )
Interesting if you run the NM and 33" tyres you can achieve very near stock drive train ratios if running the 4.3 diffs.....
Now I have not gone further into this to check if the above will be interchangeable within the Triton range of diff carriers
But hopefully when we get confirmed info regarding the MN front ARB diff lock all will be good.
Crawler gears
And this is what I was trying to work out.
Low range transfer gears for the triton are available, we run the same transfer case as the gen2 pajeros (needs to be confirmed for the MN)

Hello Mark Hardman and myself have put a lot of work into making low range reduction gears for Pajero's. They are the same gears that are sold by Marks 4WD Adapters but are actually manufactured by Hardman Bros here in Melbourne and are available for purchase direct from him.
Basically there are :-
- 2.85 which fits Gen 1 & 2 auto & 5sp (2.6, 3.0, 2.3 & 2.5 diesels) will also fit 5sp Challengers & Tritons
- 3.15 which fits Gen 2 auto (3.5 & 2.8TDI) it will fit a 5sp but with shifter rail modifications
- 3.15 which fits Gen 3 auto (3.5, 3.8 & 3.2GDI) - these gears are totally different to the earlier model 3.15 ratio
The Gen 2 3.15's will fit the ML Triton as the t/case gear part no's are the same as late model Gen 2 Paj's.
These gears transform Pajero's offroad especially if you run larger tyres as the standard gearing is barely adequate.
SO.... there are available off the shelf ratio for the transfer case of 1: 3.15 (standard is 1.9)
So A MN GLX-r fitted with 4.1 diffs and transfer case "crawler gears" will achieve a crawl ratio of 55-1 (better than a stock 5 speed manual 105 series cruiser) and nearly double that of the stock vehicle (stock MN 5 speed auto 28-1)
Very nice addition to have if increasing the tyres diameter.
So in closing there are a few items to be cleared up, but I though I would share some of the data.

as seen by Fraz- in his build up thread- linked to 3 posts up.
note that the smaller housing was also able to have the larger axles- big selling point for the pajero- never been known to be busted
going for a larger ratio like the 4.3 (of the petrol ML) or 4.6 (from the gen 2 pajero) will in my opinion require the larger housing
