Overland Journal Project Land Rover Discovery 4 (LR4)
- Thread starter Scott Brady
- Start date
woohoo...can't wait to hear what the new features are!
Update:
- Original config: 2011 LR4 with 20" P-rated tires (worked for previous owner in New Mexico)
- 30mm spacers
- 10 spoke LR3 wheels
- General Grabber AT2 LT285/60R18's which are 31.5" OD and 11.5" section width
- Stock height to fit in my FHA approved garage (no rods)
Issues to fit the above:
The 30mm spacers are minimum. One caliper did rub slightly on the ID of the LR3 wheel. Left a mark and you could hear it. Needed to kiss the caliper on the ribs. Manufacturing variances can result in some interference.
The 31.5" OD tires DOES NOT fit in the underside location without modifications. Removed heat shield, cut ends of suspension bracket/shield mount, sectioned shield into 2 pieces and remounted.
A 285/60-18 tire does require some trimming of plastic on front wheel leading edge. Will also require some trimming of frame extension / body support. (still in the works)
Load range E tires work fine. Currently inflated to 40psi but will need to experiment. At least I can now move up when loaded.
Truck now stops on snow / ice without traction control kicking in, on a dime. Probably should be worried about people behind me.
Pics later.
I have a 2010 LR4 with 18" LR3 wheels + 1.25" Bora spacers and 265/65-18 BFG AT rubber. I've added 36mm of lift using the IIDTool. There are minor rubbing issues behind the front bumper and frame horn only when the steering is cranked nearly all the way. The outside edge of the tires just graze the plastic inside the wheel well. It is noticeable when backing up as the lugs grab on the edges of the plastic and the tops of the screws holding the panels together. I'll have to post some pictures to illustrate. No rubbing at all in the back, even when under full compression.
As an alternative to using the spacers I'm wondering if the inside of the LR3 wheels could be machined away to clear the calipers or perhaps there's too much material to remove to be safe?

Thank you for the update.
I really like the General Grabber AT2 but I might go with the BFG TA KO in 265/65R18 after reading this (still like the Toyo as well).
I have the same LR3 wheels (10 spokes) which I'm planning on painting (or powder coating...$$$).
Just ordered the BORA 1.25" spacers, they come out at 32mm and I really hope it's enough (otherwise I'll have to grind the caliper a little which I'm not really enthusiastic about). They should be ready in a few days.
I'm hoping to be all set within the next 10 days or 2 weeks.
Post some pictures when you can, I will do so as well, as soon as everything is together.

PS: are you in New Mexico? I'll be moving to ABQ for a year at the end of June '14
The BFG LT265/65R18 is 31.7" OD vs. the GG AT2 at 31.5". But, section width is now 10.7" so you might experience less interference with the plastic trim pieces. I would expect the BFG to have the same issues for the spare, maybe slightly more?
Forgot to add - Instead of dismounting my original 20" tires and pulling the TPMS, I bought some ITM's. They worked fine. If I head out across the flatlands I will probably swap back over to the 20"/P-rated combo and save the AT2's.
I'm in Colorado Springs. ABQ is "in the area". I would think you will tour Colorado during your time in the Southwest. Let us all know when.

Still waiting in the spacers. They should be here around the 24th (hopefully sooner as the snow started and the Conti 4x4 are indeed crap in the snow until it's get a couple inches deep).
As I'm waiting for the spacers I'm still looking at tire options and still wondering why not go 32.1".
In any case, I'm now also considering the Cooper AT3 and the Hankook Dynapro RF10 ATm (265/65R18). Both supposed to be as good or better than BFG TA KO and better on road and on ice and snow (especially Hankook).
I'll definitely let you know when I head your way.

Excellent road-biased tire. I have 20k+ km's on a set of these on my L322 RR. Quiet, good in dry and wet, excellent wear characteristics. I don't have much snow experience with them, tho (didn't snow here last winter).

I have the dynapro's as well. I love them for the highway, awesome wet traction. They are my current limiting factor on muddy trails. However, I have no desire to play in soupy mud all the time. They have really impressed me with what they have made it through though. Honestly I think it is due to the LR3 rather than the tires, as far as making it through the slop that I have so far.
This is really good to hear as I think they're the ones I will pick.
Now I just need to settle on size. 265/65 or 275/65.

That being said. After my wife pickes her new vehicle (hopefully an LR4) I intend change to 275/65's in - likely duratracs - for something just a little more aggresive. This is because my LR3 won't be our main family vehicle, so I can afford the minor trade off potential in road comfort etc. I only have a 4 mile commute
