You need to sell your truck and buy a bike till you really decide what you want to drive.
Why you would want to ruin a perfectly good Disco with either a set of 22" wheels that ride like crap or chopping the coils.
You sound like a really young person who has been given something that you don't have a clue what to do with it and money burning a hole in your pocket.
Park it till you get a life and then think it thru.

 

I know what I want to do, I wanted to have one lifted and one lowered disco. But I can't find and have been told that there are pretty much no lowering kits made for the disco. My 04 already has 22s I bought it that way. And no I don't know alot about the Land Rover series YET. My freind has a Jeep that he shows with 20s and 35" tires so I tought about doing a similar build on my disco II since the parts might be more plentiful. Anything I've ever lifted only cost about alittle over $100 an inch so I wasn't expecting it to cost so much.

 

If you want to use your truck as a off road vehicle and you want some reasonabily large tires, look at 15 or 16" wheels and something in the 32' tire like a 265/75/16.
Something this size will work well on and off road, give you pretty good clearance with just a 2" lift. Any bigger and you will need gears, HD axles, new drive shafts and some sort of locker to give you much stronger spider gears.
If you want to talk about it, PM me your tele number and I can call you.

 

the o4 will never see off road only the 96 and I was planning on like a 15 or 16" rim 33s brush guard and some other little things for it. But for the 04 I just wanted a kind of aggrssive tire and just enough lift to fit it for on road only purposes so I'm not really worried about it rubbing while it's flexing

 

Sell the Disco and buy a jeep. These trucks were not made to stuff a tire that size, and if it's never gonna see dirt, it would be ridiculous to spend that kind of money just for looks. Get a 2-3" lift and some 18" rims with MT's if you just wanna show off. There are some lower profile MT's out there that will fit in the stock wheel wells without rubbing as long as you have at least a 2" lift. I have the factory 18" rims, and although everybody on here has told me to ditch them for the 16's, I'm keeping them, and I'll put on either an AT or MT the next time I need tires. My truck will see probably 80-90% highway, so I'm not worried about the sidewall issues with a lower profile AT or MT when off road.
