X2. I think the tire selected will work very well for your terrain.
Now if you were here in the dirty south...you might have a little bit of trouble when it rains.

Looks like the new Black Design Edition. I've seen these on a few lots, love the look. It's awfully tempting...

Spacers have arrived. The thinnest possible at 30mm and made in the USA. I am not a huge fan of spacers, but this seems to be the best overall solution to fit the tires and wheels. Pictures of everything installed in the next day or two.
I also added another 20mm of lift using the IIDTool. What you can do with a modern vehicle is incredible and frightening at the same time. It accessess 11 ECUs and I can change hundreds of settings. Want to lift the truck? 3 min. Lower it? 3 min. Remove the TPMS monitoring? 2 min. Pretty amazing - as long as all those ECUs keep working

Scott, the company below makes a thinner set with their 1" option for the LR3/4, which equates to 25.4mm. Made in the USA (Sparks, NV) also and hub centric. They will even do custom thickness as well.

Just don't try to do this. . .
Of course, even older Rovers have their limits. . .

Just a quick image and update. 33" tires on 18" LR3 wheels INSTALLED and functioning properly.
This image shows the LR4 in "Normal" suspension mode. "Off-Road" would give another 2"+ of chassis clearance. The suspension is adjusted with Johnson Rods, giving 60mm (2.5") above stock. Then I added another 10MM to the rear only, using the IIDTool. That is what this image demonstrates.
The 33" tires fit and rubbing only increased slightly, particularly at the frame horn just aft of the front tires. We are going to laser cut that panel and reweld with more clearance. The tire also rubs slightly on the ARB bumper and where the fender liner interfaces with the back of the bumper. Both will be easy to trim and clearance. In the rear, the tire rubs on the pinch weld and fender liner forward of the rear tire. It also rubs slightly on the rear HVAC lines. I actually do not see this as a big issue, as the rubbing is quite light and the lines are aluminum. Further investigation reveals that new lines could be made and relocated. We are going to monitor this as use continues.
The Falkens are pretty ideal for this truck, running smooth on the highway but have a few important construction features that allow fitment. They are tall and narrow, measuring 33" tall X 10.5" wide. They are narrower than the Mickey Thompsons we removed by 10mm, but more importantly the carcass has a notable radius at the shoulder and limited edge lug elements and features. This smooths any rubbing and helps with clearance. The 1.25" spacers also seem to help with clearance, particularly at full lock against the frame. The spacers also restore the lost track width from the suspension lift and add about 2" to the total track width, compensating for the additional tire and suspension height. The spacers keep the tires just inside the fender flares, so it doesn't look odd.
MOST IMPORTART!
Anyone that owns an LR4 can install 1.25" hubcentric spacers and use factory LR3 18" wheels with no further modification. Using a 1" spacer would require some grinding of the caliper. Use no spacer requires significant grinding of the caliper. This will save (potentially) thousands over specialty 18" wheels. We found these LR3 wheels used and only had to purchase a new spare wheel to match. Total investment was less than $1,000 to have 18" wheels.
This image shows the increase in track width from the 1.25" spacers. These tires are 265 wide. It looks correct and not goofy (i.e. sticking out past the fender flares).

Nice stance on the truck, Scott. So, just to clarify, at Normal mode it is 60mm higher than stock, except the rear which is 10mm more. Then in off road it raises two inches more. So in Off Road mode, it is now 4.5 inches + above its previous maximum height, right? What are the draw backs in terms of suspension alignment and driveline angles at 4.5+ inches of lift?

Those are all correct. With the current configuration, the LR4 works well on the trail and rarely requires "Off-Road" mode except in extreme scenarios. In "Off-Road" mode, you cannot exceed about 30mph and there is a significant reduction in ride quality and articulation. Big rocks, ledges and deep ruts are the only conditions I will use "Off-Road" mode now. As the vehicle is currently configured, "Normal" mode is already higher than "Off-Road" mode for the stock vehicle, with clearance, ride quality and traction all improving from the 33" tire. I will try to take a picture of the vehicle in "Off-Road" mode for comparison.
Edit: We have also realigned the vehicle for these new conditions. The vehicle alignment is now set to +60mm higher than stock, correcting camber, toe, etc. With the IIDTool, I can now easily lower the vehicle (lower all adjustment) for better highway stability and reduced CV angle. I plan to do this, running longer road trips at only 30mm above stock.

Any idea about tire clearance and how all this works on the L322, by any chance?
Scott Brady

I might just try that out. I do plan to install the 20s and Mickey Thompsons on the L322 with a +30mm suspension adjustment. I bought the IIDTool for the MKIII (L322) too.

From what I've gathered the L322 has more room in the wheel wells. I'm debating between an LR3 and an L322 right now. I'm kind of a Range Rover buff, so I'm leaning that direction. I would probably only go to 32 inch tires on that though. If I did that, I would look at getting a set of the factory 18 inch wheels for the L322, either new from the dealer special order, or importing a used set from the UK, and running the 19's on the street. Your LR4 and the other threads on the LR3/4 really help outline what's possible for the newer Rovers.
