I have a 1995 Disco with 2" body lift and a 2" suspension lift. I plan to purchase fender flairs, rear a-arm extension, and radius arms (if I have to). When tires are "stuffed" will they hit anything. Do I need to worry purchase extended bump stops? Thanks Tim |

Which 35x12.50's are you buying? Actualy measurements can and will vary. Also, what rims are you planning on running? Offset plays into the equation as well.
Just from the sound of it, you can just get the flares and avoid the a-arm extension, or vice-versa.

Tim,
please post the pics.
my gut feeling is that 35x12.5s will rub everywhere.

They won't rub if you use off set rims, adjust the steering stops, and do some cutting. |

sure.
there's quite a bit of cutting, off-setting the wheels, and adjustment of steering stops.
i can't say it "BME," but i have these tires on my jeep, with about 5" of total lift. they still rub under full compression, both on top, in front, and inside - despite the wheelwells being large enough to sleep in them.
on top of that.. i wonder what does LR's power steering have to say about this. in snow and on the rocks, even Saginaw steering box begins to bitch and whine.

peter,
have you boosted your saginaw pump?...its about a 20min mod and nets much better power, but make sure the frame behind the steering gear is good or it will do it in in short order.

no, i haven't.
the frame rail behind the box (it's a 76-series box, the best Saginaw had to offer) is boxed. never been a problem on these jeeps.
i am considering swapping out the vac brake booster for a hydroboost from late 70-s caddy. it will be using the same p/s pump, so an upgrade can be well worth it.

Thats a picture of Brian Jacksons Disco with 35". Note all the cutting he needed to do.

peter,
boxed or not a boosted pump will stress the frame pretty good ,my scout frame is boxed there as well and it needed a good reinforcement to stand up to a boosted pump.
I would highly recommend the boosted pump it makes 35' tires feel like little 31's and it makes the MM winch nearly unstopable

are you talking about AGR pump? |

| | Posted on Tuesday, January 07, 2003 - 04:01 pm: |

well AGR does sell boosted pumps but they are really easy to do yourself in about 20 min
there is a really good tech article on it here |

sounds scary 
normally, the jeep's steering is absurdly light. when i can't turn the wheels, it is an indication that something is very wrong (like a mud tire at full lock jammed between the fender lip and a rock), and i need to manoever somewhat instead of using my tires to modify the landscape |

lol
scary?...what blowing up a steering gear and shrapnel flying across the shop scary?
I like to turn my sidebiters into stuff and lift the front end of the truck up so having stout steering helps, but then again I have chrome moly drag link and tie rods with spherical rod ends so I might be a bad bench mark |

that i can do - but not to spread open the golden crack or like
nobody ever mentioned how strong the knuckles are in comparison to the steering box. the last thing i want is to break the ear off one. |

been there done that...lol
the light steering is more a product of volume not pressure.if you where to boost your box you would only need to shim under the pressure relief spring to increase the pressure not drill the center out or notch it down as he does in that tech article.
mine is not notched only cross drilled, then I bored the center to 3/16 and shimed the spring till I got 1650psi.
my steering is pretty light but with 7* positive caster its not a problem at highway speeds
I say
just do it |

can i do the same shit to rover steering pump? |
muskyman
| | Posted on Tuesday, January 07, 2003 - 05:31 pm: |

i havent opened one up yet but I would guess that there is a way to do it.
increasing pressure is a product of increasing the tension on the pressure bleed off valve so it depends on what kinda valve system they use |

lol, i boosted an AMC V8 oil pressure once that way... blew the fuck outta the oil filter 100ft from my garage. guess i overdid it a bit. |

Sorry, I should of posted the rims that I want to go with, they are going to be 15x8" Allied bead locks with 3" offset. The tire's I still don't know (BF KM's or Goodyear MTR's), please don't make this a tire thread. I have 255/85 16's BF KM right now with no rubbing at all. They measure 33x10 with 30lbs. Thanks fof all the input Tim |

Good choice on rims |

Tim, have you checked the articulation?

Peter, Yes on ramp I get about a 700, which isn't great, but I do have ARB lockers. If I have to lose articulation to gain height thats ok. With lockers one does not need that much articulation(within reason). Tim |
Peter Matusov (Pmatusov)

Tim, 700 is a good number. however, i should have phrased the question differently - you need to check very carefully what's happening to the tires at full stuff/full lock.
i admire and envy the efforts of those who put 35x12.5s on their rovers - but i don't think i'll ever do it myself. i've broken stuff with 33x12.5s and dana 44s, and i wasn't challenged much as far as tire fitment in the wheelwells goes.

just to give an idea - my jeep ramped about 900-1000 with 2" of lift and 31" tires; i don't think it'll ramp 600 now with 35s and 4.5" of lift. |

Quote:With lockers one does not need that much articulation(within reason). Tim
this is true to some degree but raising your center of gravity is the worst thing you can do on a trail rig. when you limit articulation, primarily up travel, as you raise a tire the center of gravity goes up with it as well causing the vehicle to be less stable.
this is why smaller tires matched to good articulation will very often work better then bigger tires with less.
locked or not
this is where the problem with big bump stops to fit big tires comes in. you allready raised the static center of gravity by installing the tires now adding big bumpstops everytime the truck goes over something the axle hits the bump stop and the center of gravity goes right up with the tire.
if you cant stuff a tire fully its just to big for the truck ....to quote the POR board "the sawzall is your friend"...but I prefer a nibbler |

Tim,
Dont you already have 35x12.50 thornbirds?
In your gallery, thats what it says, and the pictures of your truck show thornbirds.... |
Timothy Riccardi (Boxerhips)

Will, I had Thornbirds and they were rubbing all over the place. The Thornbirds measured 14.500 " even though they were 12.50's. To make it worse I was using factory rims. Like a dummy I didn't check to see how close or how much they rubbed. Tires are long gone, so I have to start this all over again. Thanks Tim |
