I've seen plenty of 35" tyres fitted to Disco's and Rangie's, but has anyone fitted 36" tyres to a Disco series 1 yet? Just thinking about what sort of lift would be required. 2" body lift, 3-4" suspension lift and plenty of guard cutting? I'm thinking the biggest issue would be how close to the rear door's the rear tyres would be. i.e. fit longer trailing arms and an A-arm extension. Offset rims could keep them away from the inner guards and they could be covered up with flares. Then there's the consequences on the driveline! Will the stock CV's hold up to 36's let alone the axles? | ||

David, Good to have you here. Your a wee bit too late  . 1st off, the Siomex do NOT come in 36x11.5, last I heard that the ETs come in 36x12.5 flavor, and the JTII´s biggest size is 34x12.5. I currently run the 35x10.5x15 ETs on my Disco and have a set of 5 Interco TSL SX in the 36x12.5x15 flavor. I also have "access" (swapping the SXs with...) to 36x13.5 IROK that are truely 36.8" tall that I am thinking of putting... Fitting: This has been extensively discussed and the Aussies have pioneered this on RR and Discos (Americans on D90 and D110)... Basic Formula for 36-35 on a Disco (with LESS uptravel) is: 2-3" suspension lift + 2" body lift + Rangie Spares (DAP in the US) flares + longer bumpstops = 35-36" tires Wheels: Best to stick to 15"s as they re cheaper, the 15" tires are cheaper and you can get them wide enough and with the good offset easily. I am running 15x8" with 4" offset currently with the 35x10.5 Simex. these will be used again for my snow/road tire (35x12.5 Interco STS). I currently have a wee bit of rubbing on the inner rear fender (where the thighs are for the rear passangers), but that will be fixed with new wheels and some longer bumpstops since the uptravel is TOO MUCH for 35s! The new wheels are 15x10" with again 4" offset, meaning that the center of the tire is now 1" ´out´ Drivetrain: Forget ANYTHING to do with Rover. After 2 (yes two) years of research (boards, sites, magazines, even trying to fit D44 stuff...) I´ve finally decided to go the Jac McNamara route. Now this set-up is said to last with 38.5"s so it should with us (despite our weight!) The CVs are Toyota ones, and we may be able to get them "longfielded" which makes them even stronger, the R&P are Toy (you can go 5.29) and the axles are JM 31 spline (still finalizing that) and the locker is a JM vacuum or air (or ARB if you opt for 24 spline). Now I know this sounds complicated, and it sure is, but I am going to get to the bottom of it and order the BEST make for each part. Idea is that since I am in Lebanon, I am shipping anyways, so I might as well get the BEST on the planet (rather than going local because shipping would be a LOT more) The above holds true for if you want to keep you Rover axles (be them Rovers or Salisbury rear...)...You can save a LOT from going with portals (Ho?) and I have debated that route, but that is for another project, and I wanted to keep the Disco "camping worthy" for the eventual family outings and I wnated it to qualify for whatever competition I want to enter in. Any Questions ? What´s on your mind? | ||

You answered a lot of my questions. I just added the OME HD springs and nitro shocks to the Disco. Looking for tires and such. You know, the wider the better with sidewall treads for that extra grip when running at 8 PSI! SAND RULES! | ||

True, In Jeddah I stick with NO lift and 245/75 16 Pirelli ATs. Reason is no $ to fix up two cars. My Disco in Lebanon on the 35s has a BETTER sidehill angle than a stock Disco (won´t tell you how we tested, but we DID test IT). Will be going 2-4" wider in a couple of months when we get the new axles. Should I fix up the Disco in Jeddah, I´d go with OME and Flares as well and run 33x14.5 tires | ||

I'm not that bold. Looking at 265/65R16 or 275/70R16 if I can find them. All the width and not quite all the height (less trimming?). As you know, it's the width and float that gets you through the sand, not the height. Any good ideas on a manufactuor? Saw some nice BFGoodrich in 265/65. Or some Michelin in 275/70. Sandman | ||

Look on East coast rovers website, they have modified a Disco for 33" tyres, although they testfited 36" but decided it would need some more minor modifications. It only has a 2" lift, anything above 3" lift is cobblers in my opinion. If you need more do what is done in Iceland, cut off the suspension mounts and weld them back on upside down, move the rear axle back 4", cut some bodywork, get new steering components and hey you are ready for 44". You even keep the original springs and shocks. | ||

Quentin, We´ve followed the ECR´s Discotech project since day one. There is NO WAY they can wheel a 36" tire on that thing without a 2" body lift and relocating the rear axle. My axle is relocated 3/4 of an inch to the back for some help ion that department. Note that I said that the suspension should be BETWEEN 2 to 3 " of lift and NOT MORE. reason being is that a. each rover is different from the other, and b. It all depends on the loads you carry. What the Icelanders do is NICE but not for what we intend to do with the trucks. They are NOT going after articulation, low CG, or anything that involves scary angles. Anyways, after going +38", good luck with ANY drivetrain. What I have done has cost me close to NOTHING compared to what the Icelanders get involved in, and I think it is the "best" solution for ME. Each one has to find his/her "best", I´m only telling you my experiences and "knowledge". Ed, BFG AT/KO always a favorite...check www.me4x4.com for some more data (I think you are already there, right?) | ||

[quote]OK, this may be a little too far the other way. These are Super Swamper SX 36s on MRT 15" beadlock rims with max offset. In the rear these 36s totally clear. They fit well and do not rub even under flex. In the front however they do rub and we don't think that a lift block in the front is going to solve it. The front axle has too much articulation and it contacts some areas pretty hard.The bad news is that we'd need to trim back the front corners of the Safari Gard front bumper (we may do that anyway), and as this is only a Stage II suspension the tire contacts the floorboards of the firewall under articulation. So basically too big... unless we wanted to go for more than a 2" lift, then it would work, but we are trying to keep the center of gravity low, and also run the biggest tires we can.[/quote] This is the text taken from ECRs website and 36" do fit (just) with 2" lift but nedd more modifications for a perfect setup. http://www.eastcoastrover.com/Discotech/D316.jpg http://www.eastcoastrover.com/Discotech/D317.jpg [quote]The good news is that the flares cover even these huge wheels and tires and would be legal in most states. So now it is on to our real tires, we've seen that almost anything short of 36s will fit with the flares and our smallish 2" lift, so looks like we'll end up in the 34-35 range.[/quote] | ||

Yeah, I know that, BUT, as far as I know and have EXPERIENCED, the 35 SIMEX (an inch shorter and an inch narrower) are HITTING under flex in the REAR even with the extended trailing arms. Either these guys have VERY LONG bumpstops and the tires go UP only an inch or two, OR they are testing on the RTI which does not tell anything. If you look at their picture with the 285/75 MTRs and the rear door open at full stuffage you can see that a couple of more inches in hight and in width WOULD NOT FIT. Now, they DID indeed reveal something to the world that the 36 SX is a nice tire on a Disco . BUT, You need more clearance, and after the cutting that the flares do and the BASIC USEFUL OME lift ("suspension upgrades for performance and not for tire clearance" idea), a Body lift is necessary to be able to articulate as much as possible There is NO WAY THE 36 SX will stuff like this WITHOUT a 2" body lift (and this is rubbing inside a WEE bit): http://www.discoweb.org/nadim/Nice%20Flexing%20M.JPG Even with the above, I will have to drop my rear bumpstops another 1-2" when I put the SXs AFTER a check in the REAL WORLD where (if?) they hit with the new wheels. Don´t forget that they had the S$ 3-link in the front, so taht is why they are getting a LOT of stuffage there, and rightly so, however, THAT debate is for another thread/day...let´s just say that I´ll stick to my Rover designed set-up with some help from some "slotted bushes" | ||

Nadim, Thanks for the BFG tip. I've been in Dubai for 3 years now. Love it. Give me a call when you hit town. SandMan | ||

Thanks for the reply Nadim. Being in Australia should be my advantage then! The 36" ET is what I was planning for, with the extra row of lugs in the centre. I was thinking with a 2" body lift, and the current 2" suspension lift I could add 2" spring spacers, fit them, and still have decent uptravel. Cutting wouldn't be a problem for me either if they were getting too close for comfort. Looks like the offset on your rims is the most important thing to keep them off the body and radius arms. I can just see a good advantage of a 36" over a 35" when the majority of 4wd's here are running 33-35" and create the ruts that would be easily conquered with 36"s. I've done the rear diff, maxi-drive locker and axles, but I guess I'd have to see how the front axle took the pain! | ||

BTW, check out www.procomp.com.au They sell the new Extreme Trekker 2, in 36x11.5 and 36x12.5 as well as a little 29.5! | ||

David, I stand corrected... LOTS of the competitors were not TOO happy with teh extra row of inner lugs and went back to the 35s. I for one would groove the inner lugs would I be running them, however, my currnet 35s will remain as is and the 36"SX will be grooved and used for competition. It is also BETTER to cut and keep the suspension lift to a minimum so that your COG is LOW LOW LOW If I were in AUST I´d simply take my truck to Rangie Spares, have coffee, tell them what I want and come back a couple of weeks later...
