Thanks guys...
Michael...I think you'd be happy to know that I ordered the JM stff last night! So that is good - Thx for your help on that.
This board and P4x4 were essential in the making (this is NOT a "I'd like to thank my agent, etc..." speech
)
As far as Simex goes, I still have them, however, the ONE essential thing I noticed OFFROAD was the fact that the ETs tend to GET A LOT OF TRACTION DOWNWARDS, i.e. they DIG IN A LOT. These IROKs do NOT dig in, they PROPPEL forward...
Not sure if my discription makes sense?!?!?!

Makes sense, although on a low traction surface wouldn't this propulsion cause wheel spin rather than traction?

Hey Tuff...
Not really...she's a great gal though...I thought we were talking about my IROKs
As far as "loose traction" surfaces go, I truely felt that the "tread" of the tires were doing there job in going FORWARD regardless of teh terrain, and teh sheer size and width allowed the truth to stay on the top and not get bellied out!
That said, I still need to get the ARBs and JM 30 spliners in for a serious test.

Thx NAM...
Its getting lighter by the minute!
All 7 seats in the barbage replaced by 7lb ones. The interior panels were all removed and replaced with 2mm checkerplate aluminium. We weighed a total of 270KG down the drain!
The front bumper will loose the "brush guard" and will be taken back 90mm for a better approach angle, the dual optimas will be placed under the passenger seat, an on-board welder will be under mine, the cage is drawn up and needs to be done, the rear bumper is drawn and need to be done to and will house another M8274-50 with plasma. All in all, I am aiming at 1.9T of weight.

Yeah...they are pretty shallow in the tread department, however, there seems to be a specific reason for that: the "balooning" shape makes them float on top of the soft ground and the tread allows for forward movement at the least resistance. That is what I felt they did...THe Simexes have at least 50% more tread depth than the IROK, but all the ET can excel in is Mud, and we see (in Lebanon) mud, gravel, rocks, snow, sand, tarmac...
Its my Daily Driver there, so that did have 5% of the decision process. Let me tell you this, its been 4 years that I have not been able to have a conversation with my passenger because of tire noise...these IROKs are STICKY (both dry and wet tarmac) and SILENT!
Did I mention that they did not need balancing at ALL? There is a VERY small vibration at 140km/h! no shreaking when braking either...
Truely astonished!
All in all, I'd go Simex ANY DAY for a 100% Mud run, but these tires will stay on if that percentage drops 5% or more.

Hey Nadim,
For a laugh, you should see what everyone's response on Discoweb would be with those 36's!
I'm sure it be something like "Disco's don't need 36's, 33's are more than adequate" or something along those lines.
Looks great though!
I take it you've done roughly a 2" body lift, 2" OME and 2" spring spacers?
Or is it another combination of suspension lift?
Extensive guard cutting too?

Davidh,
Yeah, probably the Dweb will have that attitude - too bad huh? I thought the site was dead? I'll check it out.
"To fit 36"s (actually 36.8), you need a table spoon of OME 2.5" lift, a dash of 2" body lift, and 4 cups of Rangie Spares. Put all on teh truck, cut the front flares a bit more, and ENJOY"
P.S. Extended brake lines and bumpstomps necessary for complete digestion.

Nadim,I would be interested to know the effect those wheels and tyres have on wheel bearing life. The hub bearings on Disco's and Defenders are closer together than on earlier Rangeys and therefore arn't' as able to tolerate the extra leverage imposed by the big rubber without regular adjustment.
Bill.
Bill.
Bill,
Sure will. I'll be putting new wheel bearings in when I swap the JM set-up by early August and will report when these fail after that.
I should tell you that I do a 6-month grease/tighten up job on the truck. This has been going on since it met the dirt back in 1998.

Nadim, the more I thought about it overnight the more I think there will be wheel bearing issues. The standard Disco rear halfshafts are one piece units with integral drive flanges. Although they are still technically Full floaters, the one piece design adds extra support to the hubs and wheel bearings. by going over to aftermarket halfshafts and separate splined drive flanges you lose this extra support. Come to think of it, if i were an engineer responsible for approving vehicle modifications, I would probably request that Disco /Defender owners convert to early Rangey or 110 landy hubs and spindles before I would permit tyres larger than 7.50x16. Yes I know that the front hubs have separate drive flanges anyway, but the front axle on Rovers have a lower weight rating too.
Bill.
Bill.
Bill,
You really should have a look on pirate4x4. There are plenty of guys with discos, rangies and late model defenders running tyres this size. I think some of them have had the odd failed bearing but most of them break a lot of CW&P's and even HD axles before they have to worry about bearings.

Bill, your thoughts are well addressed, however, as Ben said, this tire size is NOT alien to the Rover rear axle (although I do have to mention that this may be one of the largest on a Disco that will compete 
).
P4x4 guys have had 37"s on there for a while and believe it or not, but these IROKs are LIGHTER than the 35 ETs they JUST replaced. Everyone noticed at the tire shop, so finally we decided to weigh them and compare and there was a 3 kg difference DESPITE the 2" wider steel rims and 1mm thicker steel used there!
The truck will not tally more than 5,000km a year, and as I said before, I am extremely religious in the preventive maintanance I do every 6 months, so that should a) ellude failure and b) maintain the bearings in the right condition.
Thanks for flagging this - I will keep an eye on things.

Ben, Nadim. I always apply endurance standards on mods as if they were daily drivers doing the average 20,000km per annum, so my concerns about wheel bearings do not really apply on your vehicle Nadim.
Ever since Rover converted over to grease lubricated wheel bearings on the later Rangey classics and 110 Landeys I noticed a much higher incidence of wheel bearing problems than previous models. Not catastrophic failures, but higher rates of wear, requiring more regular adjustments. I originally blamed this on lubrication which is still part of the reason, but Mal Story from Maxidrive in his catalogue listing the variables on front difflock componentry, makes comment on the "stupid closely spaced wheel bearings" on the later vehicles. Or words to that effect.
I am reasonably sure that Mal would see the negative results of that design feature on more occasions that all of us put together. And that is on vehicles with relatively conservative tyre sizes.
Toyota LandCruisers are not well known for wheel bearing problems, and they have always been grease lubed. that is because they have well spaced bearings, like earlier Landeys and Rangeys.

Excellent looking truck.... They are so much fun offroad when theyre like that!
Keep up the great work.....

Says who????
My disco running 35x12.5-15's never did bearings.... Or needed adjustment..
Only thing was mine ran wet bearings, not greased....
Cheers Mike
Have: 110 Extreme TR edition with stuff
Had: 95 Discovery "AZZKIKR" - 35's and fun stuff!

Thats Cool
.... But of the 5 35"+ tyred Rovers I know none have bearing issues. All are running wet lubed bearings....
And I'm sure Bill has worked on many many modified Rovers...
But I have a real good imagination too
