looking at fitting 255/85's to my series one disco, it has a 2" suspension lift and am looking at putting a 2" body lift in before tyres. Does anyone know of how much guard will have to be trimmed, any probs with gearing, drivetrain etc, any info would be great. Or should i just fit 235/85's?

Darren, I think you already know the answers. You won't know how much trimming until you get the tires on. You might need to lengthen your radius arms to clear the sliders, and gearing will obviously be needed. HD axels front and rear would not be a bad idea also.

I just put 255/85s on my truck. I have 3.5" suspension lift and 2" body lift. I had trimmed my rear fenders way back long ago. After a serious test the other night, the new tires rubbed at least a little bit, all around. I think with 2" and 2" you'll be rubbing pretty seriously. My 2" springs have a few miles on them, though, so I may switch to newer ones to get back the height I need to clear everything, so I don't have to trim rear doors, sliders, arb bar, etc. Or I may go just go with 3" springs. At that point I'd have 6.5" of lift, and the tires would clear pretty well all around.

I haven't re-geared, and probably won't. It will suck in the mtns, but the truck was already slow as shit. Compared to the bias plys I was running, the 255/85 radials make the truck actually seem faster... I have noticed a change in braking distance, though.

PS- After re-reading your first post...
The 265/75s look bigger than the 235/85s, because they are a bit wider. That's the tire I might recommend for your set-up, as the 255/85 is a big step up, in terms of what you have do to the truck to really make them work.

UNLESS, you're just getting warmed up with mods, and plan on continuing with spring spacers, HD axles, etc. In that case, you'd end up like me, with a set of perfectly good 235/85s, that just looked too damn small when I got done!

I have 2" springs and a 2" body with 255/85's, and the only rubbing I get is on the frame when turning sharp turns. That is with the factory wheels.

Enoch, youv'e got to be kidding with that advice. you mean to tell us that you went to the effort of lifting your D1 5.5" and you did not address your control arms in the process?
and please, 6.5" of lift on stock control arms is just absurd, let alone way to much lift to be useful.

darren, to answer your question, yes, that is enough lift. but in order to minimize the amount of rubbing/cutting lengthen your radius arms 1/2" and install a set of Rovertyms adjustable rear trailing arms. the rear quarter behind the rear tires will also need to be trimmed a bit, but it's minimal.

and yes you will want to re-gear and you will lose turning radius with that size tire.

So how tall or whats the best tire size with a modest 2" inch spring lift. Can you fit 265/75 16 in there or is 245 the biggest.

Andrew,

245/75 will fit a stock truck, D2, and a D1 with a little trimming.

With 2" spring-lift, you can get 235/85 or 265/75 onto either truck. They're about the same height, the 265 is just wider.

Enoch is right. I have 255/85 tires with 5.5 inches of lift in the rear and the tires still just hit the rear doors under full flex. I have RTE rear links and 4 inch bump stops. The A ARM relocater could be a simple fix along with lots of trimming. Gearing does suck but we'll see how much after the new engine goes in this week.
Tires also rub a hair in the front but not enough to mark the tires. Tires are on AR rims from GCR. Stock wheels may be better for stuffing.

Thanks Brian, good to hear that from someone who actually has that set-up.

Sorry Marc, but suspension lift was only 3.5". Body lift added the second 2", and has no impact on control arms. And did I actually say that I hadn't addressed the control arms? Couldn't find where I did. I have RT rear links, taller bump stops, as well as adjusted front control arms. I have not, however, shimmed the rear links back to fine tune the driveline angle, and this would probably very slightly help the tires hitting the rear doors. Once I got rid of the roto-flex, I found the vibes liveable, and my truck doesn't see a ton of highway use anymore anyway.

At front, tires hit ARB bar, which needed trimmed up anyway. Also as Brian notices, rubbing at front end of slider is not enough to really damage the tire. As a clarification, none of my rubbing cut the tires.

One thought on why I'm still rubbing may be that I'm running the slightly wider offset AR steel rims. Stock or Nato wheels might tuck up in a bit better.

OK,
For a 33x10.5 tire, I would not go more than the necessary 2" OME and 2" Body Lift, and then you should not have issues.
You'll need to trim the rear quarter somewhat. That is MORE THAN ENOUGH for that size.
Re-gearing and the "right wheel offset" is critical as well.

huh, that's curious, since i have done this set up as well, lengthened radius arms, RTE a-arm extension and rear links and very slight trimming at the rear quarter, all on a 3" lift - no rubbing. so yes 3" is plenty 4" if more than enough if set up properly.

and Enoch, i did rear your post correctly and even at 3.5" your control arms have issues. but then again what do I know, seems to be fine for you, right?

Ya'll are having too much fun I have to chime in. I have a 3" RTE lift and 1" spacers just another way to get four inches of lift. The 255/85's rubbed hard on the rear fender (as everyone knows) and also rubbed hard on the back of the front wheel well also. I didn't have any rubbing on the back doors though like some others have, even without the A arm extender. In my photo gallery you can see the front before I trimmed it and can tell that it won't work without more lift or trimming. I chose to trim and keep my D1 lower. The pics of the rear wheels "stuffed" are after trimming was complete. The truth is there are alot of varibles: Tires of the same size from different manufacturers vary, rim width, rim offset, weight of accessories (winch, bumpers,sliders,roof racks, brand of springs)and how much you are willing to cut are all going to make each truck a little different. The list goes on and on. Bottom line is with 255/85's you will need to modify your rig ALOT more than you will with 265's or 235's if you want to do it right.

A guess the after market wheels have something to do with it. I have a set of 255/85's for off-road and 265/75's for on road. Both tire sets are on rover wheels, and rub the same spots. No rubbing when stuffing, just during a sharp turn. I could ajust the steering stops, but i'm lazy.

I might be beating a dead horse here but couldn't help checking some tire sizes because I have always wanted to get my disco to a 33 x 12.50 tire. But after reading this and other similar threds I'm not so sure. I am running 265/75R 16's with an OME shock/spring kit. With minimal trimming at the back of the rear wheel well and slight rubbing on the frame in the front at full steering lock (which I can live with) I see no problems. I am running stock wheels, radius arms and steering componets. I do notice light steering from caster being out of adjustment. My MTR's supposedly measure 31.8 in diameter. I checked the B. F. Goodrich website for the Mud Terrain. The 235/85R 16's are 9.3w x 32.0d on 6.5 rim. The 265/75R 16's are 10.5w x 31.9d on 7.0 rim. The 255/85R 16's are 10.0w x 33.3d on 7.0 rim. If people are having to replace many other suspension and steering components just to run the 255/85R 16's can someone tell me the added performance of 0.5" less tire width and 1.4" added diameter?

I forgot to mention I will regear my disco because of the jump in tire size, towing, and weak 3.9.

If that's the case why run the 265 over the 235? It's minimal difference as well. Its kinda' what you want. Why ome shocks instead of bilstiens, why yellow instead of white, I like the way they look and perform on my D1 and thats that. It doesn't make my penis any bigger though.

Oh great Ho, I already run that size.
I suppose this means I have to move up to the XZL 9.0 R16 to see any gains.
Are you guys really out of stock? If so, does anyone have that guy with the circus-looking RR Classics email address?
I hear he's importing a bunch from France.

Good Things about the 255/85?
1.Tire is really cheap compared to wider sizes
2. It fits and looks good on a D1
3. It fits well on the 7inch rim
4. The extra inch of clearance helps when you need it most.
5. It's a full on 33 inch tire!
6. Better in Mud than 265/75
7. Better on Rocks than 235/85
8. They are cheap!

are they the same width as the 265/75 r 16's? will they fit well with a 2" lift d1 on american racing steel 19"x7" rims?

i'm very fond of the dremel, and yeah, 16"x7". What about steering stops for a 265 tyre. How do they work exactly?

Perry, I guess I would have thought the extra width would help with traction as much as extra 3/4" clearance would help. But I can't speak from experience as I am on my first set of 265/75R 16s. And I went with OME kit for cost alone. Would have gone taller and more flexable if I could have afforded it.

Tim, maybe your misunderstanding me. I do think the extra width is worth it thats why I did go to the 255's. I was just having fun with the people that think I put them on to improve my sexuality. The facts is my truck runs well with them. Yeah, I had to regear and yes I put in axles and yes I had to trim a lot but thats what I bought it for. I'm not saying everyone needs this set up it depends on what they do with thier truck, where they live... But I like it.

I know what you mean. I bought my truck a couple of years ago and said I was keeping it forever. After driving it for a while and researching lots of options for disco's I have changed my long term plans only slightly. The only problem I am having with reaching my optimum disco trail rig is funding. I am off to a slow start but hopefully I'll eventually get there. I had always wanted a 33 or even a 35 inch tire but I don't know how much money I want to spend to achieve that goal, so I may settle for the tire size I'm running now and get some of the other goodies I want. And I don't have enough money to improve my sexuality!

Tim, I think you have the right mind set. If I had to choose mods the extra you get from 255's compared to 235's or 265's can be much so spend your money in other areas. I saved my butt off before I got my D1 so I was lucky enough to do the things I wanted, but I have dumped a heinous amount of money into it. Now I can't ever let it go because the mods are worth more than the truck. But, man do I love it! I went out the other day and there are some hills that people try to climb and after several lifted jeeps and trucks failed I took my D1 right to the top. Since all the other trucks were taller and had bigger tires I think it really surprised them went the little LR made it. The lockers made all the difference but I didn't tell anyone I had em' and since it didn't spin I don't know if they figured it out. I figured I would keep em' guessing.
