I currently have a 3" RTE lift on my rig, and am running 265/75r16 BFG Mud Terrains. I am starting to look for a new set of tires and was curious what would be involved to fit 255/85r16 Dunlop Mud Rovers on my truck. I have the wheel well trimmed, so that isn't an issue. Does anyone know if this tire size will fit without additional lift hardware (ie. spring spacers)? Thanks for the info.

Never seen shoes that big on a D1, but there's one way to find out - have your local tire shop slap on a set and get out the forklift, keeping in mind that what clears in the parking lot under static conditions might still rub while you're moving on the trails.

By Brian on Thursday, September 20, 2001 - 06:33 am: Edit

Ho is running this size in the BFG MTs.

By Bluegill (Bluegill) on Thursday, September 20, 2001 - 07:16 am: Edit

damn, that's about a 33x10...

By Ron on Thursday, September 20, 2001 - 07:17 am: Edit

We went over this before!

Look through the archieves

By Eric N (Grnrvr) on Thursday, September 20, 2001 - 07:26 am: Edit

I think that John (Rovertym) is running 33s.

By Diesel on Thursday, September 20, 2001 - 07:27 am: Edit

Your right Ron. I just remembered that we have discussed this before. :-)

Thanks,
Diesel

By Ron on Thursday, September 20, 2001 - 07:34 am: Edit

No problem diesel

I have a pretty good description of what you will need. Also keep in mind the Dunlops in that size are TALLER than spec. so are like 33.5-34in

Cheers
Ron

Ron,

What should we search on that will bring it up quick? Any particular keywords?

Tom

By Diesel on Thursday, September 20, 2001 - 08:21 am: Edit

Tom,

search "255/85"

Ron, send me the description. sojourner0123@yahoo.com

I have searched for you all, here is Ron's old message:

"I saw a disco with 255 85 R16s on it.

To do it you would need:

CV front drive shaft (almost certainly)
CV rear drive (maybe because of the next thing)
Longer rear trailing arms (moves tire back away from the door) Or buy those with weld on mounts and weld them on a little further back
Longer front radius arms (same idea)
Wide offset wheels or wheels spacers.
Good idea to get longer bump stops
Definately longer brake lines and of course new shocks and mounts
Depending on how much weight you carry you may even want/need spacers to go even higher.

To go from 2in RTE springs and 235 85s to 3in RTE springs and 255 85 is a real undertaking.

The other way to go is just to mount them and let them destroy your rear door and back corner of the front fender but that looks like hell and does not work to well.

The main limiting factor to bigger wheels on a disco is how far back you can move the rear axle without hitting the fuel tank, alternatively you have to cut the rear door which will prevent it from sealing properly.

Cheers
Ron "

By Ron on Thursday, September 20, 2001 - 08:31 am: Edit

Thanks Tom,

I would like to add that the disco in question also had RTE a frame spacers for the wishbone and was running 255 85 dunlops

Ron

By RVR OVR (Tom) on Thursday, September 20, 2001 - 10:10 am: Edit

Ah, that was my big question...i know the a frame spacer is needed for pinion angle.

What about front end mods for steering (panhard rod)?

Tom

By Ron on Thursday, September 20, 2001 - 10:20 am: Edit

He was running a stock front Panhard rod with the set up when I saw it, but he said he had an extended one for when he but on the other springs. If you run a stock rear drive shaft then no spacer should be needed. But in your case Tom you should get a spacer to point the dif up toward the t case. If you do it right you can have it set up so all of the spacers on the RTE rear links are used which moves the tire back from the door.

hehe, CV breakin action soon to come. Diesel, you gotta upgrade that front axle. Brian Jackson broke 2 cv's using them big meats. I'd go for front and rear axles, gears and better diffs. I too want that tire size, but would rather have reliability than the extra clearance and "cool" look.

http://europa.vcu.edu/~ahang/CT/I_hate_CT.htm

here's the some pics of the butchering, i mean trimming you gotta do. BJ runs about 5" of lift.

By Ron on Thursday, September 20, 2001 - 11:19 am: Edit

Man I miss Brian, he was so much fun when he was on Discoweb all the time.

Ron

PS you could definately do it with less than 5in of lift.

PPS Considering he broke the cvs with 120k plus on them I don't know that it is that huge of an issue. He was also running a TT which is not a rough on cvs as an ARB.

By Frank Avent on Thursday, September 20, 2001 - 11:59 am: Edit

Here is what 33-12.50-16 Super Swampers look like on a Disco (almost equivalent to a 285/75)

Frank - Great looking truck. Did you have to do all the stuff stated above or did you simply trim to get it done?

Please, fill me in on the setup...

Thanks,

Tom

By Diesel on Thursday, September 20, 2001 - 01:10 pm: Edit

Al,

I think you are right about the CVs, replacement would be necessary.

As far as the tires go, I was just considering my options at the moment. The BFG MTs I have need to be continuously balanced even if there is no offroading involved. Just to clarify that statement, the tires I am running were used when I bought them and had little bits missing everywhere. I bought them so I could figure out what kind of tire I really wanted. I think the mud rover would fit me needs and tastes nicely...of course at the moment I need a different size...perhaps another set of 265/75r16s.

Ron,

Are all the Dunlop Mud Rovers taller than spec? Are the 265/75r16s bigger than a 32"?

Thanks all for the excellent info,
Diesel

P.S. Frank, very nice rig.

By Ron on Thursday, September 20, 2001 - 01:17 pm: Edit

Diesel,

Actually my experience is that most dunlops run a tad small if anything which is why I was surpised when I measured the 255 85s. I don't know for sure about the 265 75 R16 Mud rovers as I have not seen them mounted on a truck. Could be taller could me shorter, I dunno sorry Maybe someone else will know?

Ron

PS yes I do in fact carry around a 36in tape measurer at all times

By Lantu on Thursday, September 20, 2001 - 02:06 pm: Edit

My friends, I dont' understand how you people can see a Discovery that is really ruined in the body, and call them "nice"

It makes me sad to see them with so much damage.

I guess some damage is innevitable, but I always thought that "easy does it".

Just out of curiosity, why hasn't Brian J posted in a while. I remember the days when his subject headers were a paragraph long followed by "n/m"

Diesel,
most above tips and mods list are very valid.
what nobody talks about is the misterious vibes, steering issues, and the boinging factor.

so, if you are really into that size, just do it, and see what you really need. for sure it will eat up some good chunk o' cash.

good luck.

By Moe (Moe) on Thursday, September 20, 2001 - 08:11 pm: Edit

>it will eat up some good chunk o' cash.

For a potential 1/2" extra clearance it does seem like a lot of work and cash outlay. I hope that if you are going that way you would have already taken care of a few of the other essentials.

Diesel, are the 267/75 holding you up that much to require a bigger tire?

Moe

By Diesel on Friday, September 21, 2001 - 03:08 am: Edit

Moe,

265/75s have worked for me so far. Like I said, I was just considering my options. If you convert 255/85 to inches, it is about a 33" tire. According to Ron, it is taller than spec which I didn't know. So, consequently, there would be more involved making almost a 34" tire fit well. For now I am sticking with the 265/75s.

Diesel

By kyle on Friday, September 21, 2001 - 05:56 am: Edit

The bottom line is. How much are you willing to hack on the truck ? Its not rocket science to get the giant meats on and if you buy 9 million dollars worth of shit or not you will still have to get happy with an implement of destruction on the body of the poor thing. Once you have started hacking whats a little more ? Also , you go moving the rear back and the front up your geometry is getting all hosed up. But , I guess it dont matter , your springs can never really compress in the same fashion again. You will have some big ass red bump stops on there to keep that from happening...


Kyle

Thanks everybody for explaining to me.
My Discovery series II is still nice and shinny. and I hope I can do adventures without damaging as much as some of you.

Hope I can learn how to keep my Discovery from being a "cool" vehicle.

Hmmm , gotta be leary of this one....
