Thanks so much for everyone's input! It's been fantastic to hear what you all have to say about yer boots!
The recent posts about speedo accuracy also lean towards the topic of extra stress on gearbox / diff etc etc.
I noticed TJS-70Y posted some new pics of their D2 here.. http://www.aulro.com/afvb/discovery-...s-your-d2.html
and mentions having blown the rear diff (damn!) -- anyone care to comment? The fella at the tyre shop was adamant that larger OD means trouble.
Cheers

G'day.
Just thought I would let you know that the rear diff blew in my D2 as a result of not having a CDL for most of its life. Without it all the weight of the vehicle is put on to the rear diff offroad whilst most of the drive is sent to the front diff.
What happened in mine is that the centre pin in the diff had come adrift. It then had enough force to break free of its containment in the centre. This destroyed a side gear in the process. I have a CDl now fitted and I believe that now with it locked there was equal force distributed front to rear. Ie 50/50. Before it would have been more like 80/20 front to rear. It's hard to say if the tyres caused this as the ground wasn't very slippery. I would blame the cross pin not being secured more than the tyres. The front diff has the same problem, the cross pin is not secured and there is a good chance it would have let go soon too.
I am led to believe that a lot of people that retrofit the CDL into their D2's end up blowing a rear diff. Not all just a few.
Hope that helps.

Firstly I have a 2002 model TD5 series 2 that currently has 18 inch rims which have limited my tyre choices. I have coopers HT's on at the moment and they just aren't cutting the mustard off road. I have raised my vehilce by fitting Bilstien shocks and King springs to give it about 2 inches lift. I have recently been given the original steel rims (16x7J) from my vehicle (bought my disco from a mate).
The Question........... Can I fit Coopers LT245/75 R16 STT's to my disco? if so will it effect the performance (especially when towing) or what other suggestions do you have. He has also suggested as a fall back 255/70 R 16 ST Coopers as a fall back. I would prefer the STT's as am planning on doing some serious campingin the future (Cape York, Gibb River etc)
thanks in anticipation of someone being able to help

Preeds. Be careful of the 255/70 R 16 S/T Cooper ... THAT particular tyre is NOT an LT construction ... it's passenger construction. I know, I have them fitted to my D2a ... about to fit 2x new ones today ... (previous owner never did a wheel alignment & 1x has scrubbed out) ... they've done 70k so far and still have an easy 20-30k left in them. Grip well, sand/beach work is OK, I have no complaints. (flame retardant suite ON) :) .... came with the vehicle and so far so good (about 14k since I've owned it).
The LT version of that tyre is 255/75 R16.
The std tyre for a D2 is 29" diameter (235/70*16 or 255/65*16 or 255/55*18). The 255/70 I'm running is 30" (3.5% increase) and the 24/75 is 30.5" (4.9% increase) ... I don't think that would be too much change in your final gearing ... folks here seem to be happy with 265/75 tyres ... that's 31.75" .... or about a 9% increase ... !
See *Alloy Wheel & Tyre Size Calculator for Mr UP's excellent tyre size calculator.
Kev..
They will fit and the vehicle will perform fine.Quote:

Ive got some 245/70/R16 cooper stt on my 99td5 disco and i reckon that they are great on gravel rd,sand, mud and they make little noise on the hiway.
Did notice though a slight speedo decrease, and a little less down low, not too much to worry about with a Ecu upgrade.
cheers bronson;)
Thanks Bronson
am currently on coopers site looking at tyres sizes that will fit my disco, they dont have a 245/70 listed in STT, the best I can find is a LT 255/70 16 STT with a diameter of 770mm. My current diameter is 736mm so will increse by 34mm. I have had an ECU upgrade also to my disco but was wondering about performance and also my insurance as they say on Coopers site that you are allowed to go up by 15mm (currently under review to 50mm it states also)
am also looking at the LT245/75 16 STT's with a diameter of 780mm
thanks for advice
