Thread: 265x75x16 on D1 mags and a planned 2" spring lift on a 98 D1 300tdi Auto. Will it wor

The 4.6 might hold a bit better than the 300tdi.
But that is the second time I’ve had that advice this year and never heard it before.
Will try that next time I’m bush.

I run 265-75-16 on my 300tdi and have done so for last 9 years....

works for me, it is indeed a bit sluggish maybe, but mine is manual, so you learn to compensate a bit for it.
standard gearing and diffs.

negative, if you like, is full lock - need to practise your 17 point turns in carparks as the width of the tire rubs on your radius arms.. I only adjusted mine last year (little full-lock screw (not sure of correct terminology here , stops the rubbing, but won't give you a better turning circle.

also probably using slightly more fuel I guess - running a diesel/gas system, so that helps the sluggishness and the fuel economy a bit.
and you will need to cut your arches, otherwise you will chafe on articulation.
I never used spacers or anything, just 2" lift and cut the arches.

I briefly owned a 300tdi auto with standard wheels, and I noticed it ran a bit quieter on the highways not only tire noise, also less revs - I might sit at close to 3000 at 100km/h, standard tires sat on 2500 or so...

Good luck, enjoy and have fun!

hi gerry,

low air pressure solves most sand issues...245x 75 on my auto works well...I have 265x75 on my manual disco (also 300 tdi) and that seems fine...my old 76 rangie was far better on sand....v8 power no doubt...standard tyres, no probs at all (pay for it at the pump though)

my auto remains set up for desert runs with cooper st max all round. unfortunately my manual disco is now un-licenced...me now getting old and like the ease of auto...my 2" lift is king springs (probably closer to 40mm) with bilsteins all round sourced from Smiths in albany...

regards robbo

I have just spent an hour or more thanking you guys for your great help (maybe longer). But, because I started this thread earlier (3-4 hours ago) and I left it "on hold' it stuffed up for me and wouldnt load to the Forum. Then it decided to totally **** itself. I am not very happy as I spent a lot of time thanking you guys and putting my theory forward about wide vs not so wide tyres. I also decided that after a lot of deliberation I will go with 245 75R x 16 tyres. ok, see ya guys, I am old and tired and in need of copious amounts of beauty sleep. I mean massive amounts.


Bye for now - Gerry

I have a set of Yokohama 245/70/16 AT's fitted at the moment and have No problems even on the soft fluffy sand that the WA beaches are infamous for.
I will be heading up North for 6-12 months where I will encounter some black soil country, rocks and gravelly/muddy bush boat ramps` and as I have upgraded my boat from a 12' tinny to a 5.4M Trailcraft boat which is significantly heavier I an thinking of fitting a set of MT tyres.
The new Yokohama Geolandar M/T G003 tyres look the goods But I can't get them in 245/70/16, 245/75/16 is the closest I can get.

At just under $400 per tyre I hope these are not too tall for my standard height D2a as I will need 6 of them (4 on the truck + 2 spares) and it will be an expensive exercise if they don't work out.
The 245/75/16 MT tyres are rated at 1,400kg where the 245/70/16 tyres I have fitted are rated at 1,090kg.
The upside is that IF I buy 6 of these tyres I will get another 2 tyres free because of their buy 3 and got one free promotion.

Has anyone got these tyres or other 245/75/16 MT's fitted?
If so is there any drawbacks with the taller tyre fitted?

other than the speedo being out by a larger margin .. not really!
Brother has 245/75's (BFG KO2)on his D2(TD5, chipped) and it drives really well.
I have Yoko G012's on my D1(255/70's) and his KO2's are quieter.
Don't really know if this is due to the taller aspect ratio or just the tread pattern.

I've had (semi)mud tyres on my RRC a long time ago in the form of Pirellis.
Not as good on sand, more so soft fluffy sand. Not really bad, but a lot more work.
My experience with those tyres and my subsequent yoko geolanders(can't remember which models they were tho .. back in the late 90's) on sand out in the mallee desert areas, the yokos didn't need lower tyre pressures where the pirelli semi muds did.

Pirelli tyres were the old(no longer stocked) FD44's with a brick like pattern.
Not full muds, but 'muddier muds' than the AT geolander's were that replaced them.(same width and aspect ratios).

The only gotcha you'd want to double check if you do fit 245/75's is the front steering lock clearances at full lock.
Make sure they don't bind on the chassis or inner guard(I don't think they will on a D2, but you never know). If they do, tweak the lock stop a smidge to eliminate that. easy to do, but you'd get the tyre fitting place to do it for' ya.

my plan for new tyres when my Yokos wear out is to also go with 245/75s too. Just not sure which brand/model yet.
At the moment I'm swaying between the KO2's and the Duratracs.

Have ko2 245/75 on mine. Noticed a bit of difference with taking off but not nothing a pump tweak can’t fix. Hwy is nicer in terms or revs n fuel but makes it a bit slower at overtaking which you shouldn’t do in a d1 anyway unless you are on 90 mile straight.

The main thing I noticed is that breaking wasn’t as good. Not sure why. It almost caught me by surprise first time. Now I’m used to it but will soon upgrade brakes.

Generally i like the 245/75 much better. Once i get a ic n turbo upgrade it should be better than before.

How do you find your king springs? Are they the progressive springs?

This is where I reckon running a Defender Transfer Case would be great if u are still wanting to run tyre size of 235/85/16 or bigger. From my calc's it would be equal to, if not better with the 1.4 Def TC than if u were running the standard tyre size. Towing would be better too, but one of the down sides is when in high/steep country and the lack of engine braking when compared to std tyre size...
