I purchased the Yokohama Geolandar AT G015s. So far they are fairly quiet compared to KM2s and Michelin XZYs. Significantly lighter than the XZYs so low speed turning and acceleration feel quicker. No change in mpg so far from the XZYs. Wet traction is very good on new and old pavement. They clear out rocks/pebbles well when driving.

Does anybody have any feedback/experience with any of these tires in 235/85r16 e load range:

General grabber AT2
Yokohama geolander A/T G015
Cooper discoverer A/T3
Cooper discoverer XT/4

Thanks.
They are a hundred more per tire and for 99.9% highway driving at 70 miles a day for work I can't justify the KO2s. These need to handle occasional nonpaved road that may be wet or snowy, snow on the highway, highway, and probably 1 trail ride per year hence these non-extreme tire choices.
Late to the party, but I'll put this info up.

I got the AT3's back in Jan for my Taco (265 70/R16) and have put about 15k mi on them doing basically what you describe (55 mi roundtrip, snow, rain, dirt/mud roads, pull a boat out of the water). I like them. Not loud, seem to be wearing evenly (across the tread). Good wet traction. Work ok in mud (4-6").

Down side - I've had to have them rebalanced at 10K, and I'm starting to feel a shimmy come back at 15K.

I'd recommend them.

Regarding the initial post, I would disagree that gearing becomes an issue with the DII on 285/75 tires. Drive shafts aren't really an issue either, though the roto should be replaced with a u-jointed rear shaft if the rear is locked. IME gearing only becomes an issue on a DII at 35's and above, and then only if the truck is driven on the highway.

Regarding the negative comments on ATs for strictly on-road use, my DD is a Mark III RR running the original Nitto Terra Grapplers and they are great on a rig that sees 95% pavement and 5% gravel road. A good and different look compared to the norm and run just fine on the highway with minimal noise. Plus they're there if/when you need them. I routinely commute at 80-90 mph on these tires and have no complaints. And yet they would do fine as an off road tire on a DD in the Rocky Mountain West (though I would prefer a BFG AT).

My old D2 on 255's and stock gears was a dog in the mountains; it couldn't get out of its own way. Of course, I drive like an old lady so it wasn't too much of an....issue :rofl:

Same here on skinny 34's. I find myself downshifting to 3rd on hills to keep the transmission from hunting gears.

Well, admittedly it may have something to do with my having lost about 800lbs off the truck....

No idea. I ran 265/75R16 and 255/85R16 on a D2 with the normal 2" OME lift.


Sorry to revive this


Do you think 255s or the 285s would be better with a 2in lift? If you were ok with the 255s a 285 should also fit yes? It's a little shorter but inch~ wider.

Anyone have experience with these sizes on a D2 with 2 inches of lift?

Doing it again, I would stick with 255/85 on a D2. 285''s are a little too Hot Wheels for me.

I agree on that for a mildly modified D2 if the goal is to retain it's original design intent of great all-around travel 4x4 blend. However on my lr3 with fender liners modified, I've been test fitting 33" 275/70-18 in bfg at ko2 & duratrac, then also the bfg km2 in ~33" 255/80-17 and 33.7" 285/70-18. The 255 fits really well in full articulation but just seems too skinny for the heft of my 7000-8400 lb lr3 when running standard vs loaded for trips.

Having the 255 km2 in front of me though, it looks like it would be a really great choice on the D2 which I'd like to continue setting up with lockers of some sort and mild 2" - 2.5" lift. The medium duty OME 1.5" right now is just not quite right.

(also: i've been running on the lr3 for couple years now 275/65-18 32" with full bump stop drop capability after the fender liner mods.)

Discovery

245/75-16: Popular size for OME suspension lifted vehicles. require slight trimming on the rear wheel well fender, and may also call for adjustment on the steering bumpstops.

215/85-16: Same height as 245/75-16. but narrower. seems to be preferred for the snow and mud.

235/85-16: Same height as 265/75-16 but narrower. And seems to be the most popular size with OME lift.
Does anyone know if the 215/85-16 or 235/85-16 require trimming as well, or do they clear easier because they're narrower? Planning on an OME 2".

98 Disco 1, 2 inch lift, installed 235/85-16's, run the easy trails, I had some rubbing at the rear quarters, will definitely need some cutting, I think it's referred as the "camel cut ".

Are the 215/85 really that sketchy on the road? 235s suck so much power, 245/75 seem like the best compromise
I?ve had a set of 215 85s on a grand Cherokee and they did just fine on the road. They were from tirerecappers and appeared wider than all the ones you see pictures of on the internet. Can?t speak for them being sketch on a discovery but the ones I got were just fine.
