A few novice questions about the 04 Dll

[muskyman]

from the EE site:

For example, Ho's Disco2 is fitted with 751 front springs and 763 rear springs, which provide a 3" lift on the Disco2. Even under the weight of the Superwinch X-9, ARB Freezer/Fridge, 15-lb. Power Tank, Safety Devices Highlander Roof Rack, and loaded Pelican Cases, this truck is not sagging under the weight. The 235/85-16 size Michelin XPS Traction tires also give more trail clearance without ruining the the vehicle's overall proportions.

and...


Ho's Disco2 was fitted with Old Man Emu springs but had a 3" lift over the factory height. He is able to achieve this 3" of lift by fitting 751 springs in the front, 763 springs in the rear. Shocks on Ho's Disco2 are the Old Man Emu N107 and N108 Nitrocharger Shock Absorbers.

Here is a perfect example of my point, Ho could run any size tire he wanted after all the miles of highway and trail he has been down in D1's and DII's he selected a 235 85 16 on stock rims.

This size has really shown it self as a almost magical size in Disco's IMHO. if you go any larger and you now start breaking stuff in the driveline, go any shorter and you cant really air down much without dragging your belly.

Anybody have the measurements from center wheel cap to bottom of fender with those springs?

I want to see if it really Does give 3" over the stock heights. Stock wheel center to bottom of fender: Front is 19.7 +/- .6" Rear is 19" +/- .6

For the Discovery II.

I'm with you on the tyre size - I think 235/85-16 is a great size for a DII which is going to do any off roading. I'd probably take my chances on hurting the alloys too, but swtiching to slightly narrower steel wheels is a good option.

Narrower tyres with a bigger diameter are better for almost any off-road conditions, IMO, as long as they can be aired down quite a bit. (Some are better than others in this respect).

I'm not sure I agree entirely about the whole airing-down/ground clearance thing, but it's no biggie - same conclusion!

245/75/16 is 1" shorter, 1/2" on a radius. Not a huge deal for ground clearance. 245/75/16 seems to be a more common size, available in more styles, and maybe more readily available in stock.

I think either is a decent way to go.

My biggest fear with the 235 is sidewall exposure. It's bad enough with the 245. Here's my 245 S/T-C at 15 psi.

Ho....... on stock rims.

Things are not always as they appear Look again really close.

What do you guys think about a 285/75 r16 on a 7" wide rim. It makes the tire around 10.5"-11" or so wide.

It's about a 33" tyre and more than 11 inches wide. Too big for a Discovery unless you're prepared to mod it quite a bit.

Plus, if you air a 245 and a 235 down by a given amount, the 235 will lose more height than the 245...

 

[R_Lefebvre]

Yeah, that's probably true, though the numbers all get a bit wooly when you're talking about such a small difference and such low pressures. Different tire constructions, etc. But yeah, the difference is minimal.

In any case, I normally only go down to 20-25 psi because of the sidewall issue. Maybe because I don't have enough experience, but I'm not too comfortable with my sidewall being that exposed. Not to mention, with a wide wheel on a narrow tire, there's not as much force holding the tire bead against the wheel for a given pressure.

When you go bigger than 32" on a DII, the lack of power becomes more apparent- although the 4.6 has more to offer than the 4.0's.
On mine, the 265-76-16 is borderline making me want to re-gear the diffs or the transfer case because it hunts for gears constantly on the road when doing hills. I would think going bigger than 32" would make that problem much worse without changing the gear ratios either in the diffs or transfer case.
As it stands now, with stock alloys and the 265-75's I can go from bumpstops to full extension (running 2" extended shocks and 2.25" lift) and nothing rubs except for the tires touch the radius arms at full lock when turning.
