Here's the best, recent (March 2012) off road tire review I've found online - it's from JP (Jeep) Magazine. If you know of another comprehensive one please share:
The Hot Sheet: 33 Off-Road Tires Tested - Jp Magazine
Every few years we serve up a smorgasbord of information on tires tested by our esteemed staff. Like discerning food critics, we call ’em how we see ’em. If Trasborg thinks the lowly growl of a mud terrain on pavement sounds like a Cessna during takeoff, we’ll say so. When Stover shreds a sidewall without even trying, you read about it here. If Hazel finds that the lacking of lug spacing on an all terrain compromises traction in the mud, you’ll hear about it. Each evaluation is concluded by a series of scores in the six categories we feel most accurately represents what you do with your Jeep.
Tire Ratings
We’ve indicated specific terrain performance with easy-to-read graphics shown here. On a scale of 1-4, with 1 being crappy and 4 being the best, you should be able to locate the proper tread for your favorite terrain effortlessly.
**** This is the tire you should be running.
*** It’s a decent choice and will work well.
** Better tires are available, but it’s acceptable if you don’t mind compromise.
* We’d recommend a different tire.
BFGoodrich Baja T/A
The Baja T/A was developed for the competitive desert racing community. It doesn’t shine in snow or ice, and on the trail it lacks flexibility and sidewall bite. However, these purposeful treads offer stellar performance at high speed, both on dry pavement and in desert terrain. The carcass is incredibly tough and heavy. Despite the robust construction, this tire is well balanced and happy at speeds in excess of 100 mph. We’ve seen desert race vehicles shred cast aluminum wheels while the Baja T/A tires wrapped around them remain intact and ready to continue the race. Thick sidewall overlays deflect rock damage and enable this tread to maintain responsive steering at low air pressure, but we really consider them an off-road, go-fast race tire—not something for your daily-driver.

BFGoodrich All-Terrain KO
We think of the A-T KO as a civilized older brother to the BFG M-T KM2. What it lacks in aggressive void spacing it makes up for in on-road politeness and tread life. Despite square shoulders this tire offers many surprises; in the sand and on snow-covered pavement, the pattern’s interlocking tread elements featuring micro-siping enables a surprising amount of bite and returns ample traction on dirt and rock. Also, the lack of circumferential grooves tends to make this tire more prone to hydroplaning than more modern all terrain offerings. In deep mud the voids fill up quickly and require heavy throttle application to clear. Dry pavement is where this tire outshines much of its competition. The 3-ply sidewall design features radial ribbing near the shoulder that interfaces with terrain when aired down.

BFGoodrich Mud-Terrain KM2
The M-T KM2 is often referred to as the working man’s Krawler. Sharing the Krawler’s broad, blocky tread elements, but on a condensed scale, the M-T KM2 is a winner in almost every terrain type our editors could find. The only exception was ice-covered roads and side-hilling in snow. On icy roads the lack of siping caused the tires to spin excessively and required a lot of driver effort to slow the vehicle down. We’ve had a few experiences that make us wonder about the puncture resistance of the sidewalls, but for the most part this tread receives regular recommendations from our staff. The noise level that this tire produces on the highway is quite noticeable, but no more than many of the other mud terrains we’ve tested. With 3-plies in the sidewalls and another three in the makeup of the carcass, this tire is one of the lightest mud terrains available today.

BFGoodrich Krawler T/A KX
The BFGoodrich Krawler features a bold tread design designed with competitive rockcrawling in mind. Prior to its introduction, few tire companies even acknowledged rockcrawling as a separate segment of off-road. Today, few tires come close to the performance of the Krawler in heavy rock. The flexible carcass and tough sidewall work together to envelope obstacles while large, soft tread blocks separated by staggered voids pinch terrain to propel the vehicle. Our staff commented about the Krawler’s awesome puncture resistance on more than one occasion. The only negatives to report are the Krawler’s high weight and its propensity to wear quickly if driven on-pavement often. Also, it doesn’t work well on icy surfaces. Overall, we recommend the BFG Krawler to anyone who prioritizes off-road performance over on-road noise and accelerated wear.

**** Cepek Crusher
With a tread reminiscent of a Super Swamper Bogger, the Crusher excels in mud, sand, snow, and rocks. The pattern doesn’t lend itself to off-camber driving, but it makes up for that with paddle-like traction in soft terrain. On the street, the Crusher emits an audible hum compared to other mud terrains. In colder regions this tread has trouble dealing with ice-covered roads, so we don’t recommend it for such use, but if you want an extreme off-road tire that wears well, balances well, and you don’t care about noise, this could be your tire. The crusher is tough, with 3-ply sidewalls and 6-plies in the tread area. In addition to acting tough, the sidebiters feature skull-and-crossbone elements that bleed testosterone. With sizes offered from 31- to 35-inch diameter, the Crusher is great for Jeeps with mild suspension lifts.

**** Cepek Mud Country
One thing we have noticed about **** Cepek tires is the consistency in terms of balance and roundness. The Mud Country is no exception. Despite canyon-like voids and big, chunky lugs, the tire rolls smoothly and exhibits road manners akin to a much milder pattern. Each individual tread block is interrupted by a sipe that stops short of the lug’s outer perimeter. This adds stability to the pattern and enables additional grip for wet pavement, snow, and ice. In the sand, this tire satisfies, delivering traction that is on par with most other mud terrains we’ve tested. For serious mud bogging, however, we suggest another member of the **** Cepek family, as interior voids tend to fill up quickly and hold mud tight. The sidewalls of the Mud Country add little to the traction equation in the mud, so when airing down use the conservative approach.

Falken WildPeak A/T
For such a mild looking tread, the WildPeak A/T surpassed our expectations in terms of performance off-road. Much of the punishment our staff subjected the WildPeak A/T to included heavy rock, deep mud, and high-speed gravel, and sand. We even managed to challenge the compound to some unforgiving lava rock near Flagstaff, Arizona, with little consequence. In virtually all aspects, the pattern returned positive results. However, we remain suspicious about the long-term puncture resistance of the thin sidewalls. Though our staff didn’t experience any flats, the WildPeak A/T did fall short when it came to braking in the dirt. It wasn’t really an issue on-road, but off-road, we found that these tires lock up and skid more readily than others in this category. As expected, the WildPeak A/T shined on pavement whether it was wet, dry, or snow-covered.

General Grabber
Our testing concluded that the overbuilt 7-ply carcass would take on anything nature could dish out, and keep returning traction free of punctures, tears, or deep gouging. On the street, the Grabber is heavy and robs power, but inspires confidence on rain-slick pavement thanks to the long angled grooves that channel water to the outside of the pattern. When aired down, the sipe-free tread blocks left us wanting more bite when compared to others in the segment. Additionally, the pattern returned less than desirable results in icy conditions, which is to be expected from a tire with an emphasis on desert performance. Overall, the Grabber has proven itself among the elite desert racers as a formidable competitor to other tires in the segment. We recommend the Grabber for the go-fast Jeeper who doesn’t mind a heavy tire that howls..

General Grabber AT2
Like the BFG AT, the Grabber AT2 has a broad repertoire of strengths. Thanks to its deep treads and abundant siping, the interlocking tread lugs are able to resist hydroplaning in the wet and provide stellar grip in snow and ice. However, in mud the narrow voids fill up quickly and despite heavy throttle application, cleaning was non-existent. The pavement is where these tires shine best. Even on steep, twisty mountain roads, our tester was able to push this tread hard into corners, perhaps harder that any sane person would, and the tires maintained contact. With virtually no road noise and great all-around performance, the AT2 is a good choice for daily drivers that need added traction for weekend adventures, no matter sand, rock, rain, snow, or ice. Just go easy on the mud whompin’.

Goodyear Duratrac
One of the most aggressive all terrain tires we’ve seen from Goodyear, we think the Duratrac blurs the lines between all terrain and mud terrain. As such, our staffers subjected the tire to a whole assortment of surfaces including rocks, sand, snow, mud, and ice. The pattern stood up to heavy rains and ice-covered asphalt, and returned a quieter than average road noise. In conclusion, the tread scores highest in snow and ice traction—probably because of the plethora of multi-angle siping on every lug. However, the pattern also proved worthy of mud, sand, and rock. Just don’t get too deep into rocks with sharp edges as the compound will chip and cut easily and the 2-ply sidewalls are more vulnerable than you might expect. For a daily-driven weekend warrior, these tires are a great choice.

Goodyear MT/R with Kevlar
It’s an asymmetrical design that delivers both aggressive and tame tread characteristics. On the outer edges, the pattern almost appears to be grooved—like a purposeful mud-bogging tire would be to add void spacing. On the inside however, there is a column of tightly packed tread blocks that maintain a seemingly continuous rib for street-friendly performance. The on-road manners are pleasant and relatively quiet, with none of the vibration or harshness we expect from tires with high void ratios. In the mud, the pattern cleans well, and when aired down, the 3-ply sidewall is flexible enough to envelope rocks the size of tennis balls. Speaking of sidewalls, Goodyear included Kevlar fibers to the MT/Rs sidewalls to add puncture resistance. If you want a mud tire that shines both on- and off-road, the MT/R with Kevlar is hard to beat.

Goodyear Silent Armor
One of the quietest tires we’ve tested to date, the Silent Armor packs Goodyear’s exclusive Kevlar fiber technology with a sophisticated pattern. That’s not to say that this tire isn’t off-road friendly. It’s just not as well equipped for deep mud and heavy rock as we’d like on our 4x4s. The two circumferential grooves shed mud, but the rest of the pattern holds on to it like a fat kid holds a Slurpee. However, the shoulder lugs have larger voids between them and are able to supply bite when the middle looses traction. This split personality allows the tire to work well in the sand and snow. On ice, the abundance of siping combines with a compound that remains flexible at low temperatures, netting favorable results and our highest recommendation for winter operation.

Kumho Road Venture MT
The Road Venture has surprisingly good on-road manners. The massive tread voids help channel standing water away while also promoting self-cleaning in the mud. The cut- and chip-resistant compound provides a good ride quality, but our testing indicated that the stiff sidewalls required a little breaking-in to work in heavy rock. They did prove to be a bit aggressive for sand and soft dirt use, and we did notice that ample throttle modulation was necessary in order to keep them from digging holes. Otherwise, these directional tires are definitely worthy contenders for daily drivers. Despite their big, blocky lugs, they offered a surprisingly low level of noise on the street and rolled smoothly without major lug slap. Plus, they just look cool.

Maxxis Creepy Crawler
Among bias-ply tire options, the Creepy Crawler delivers superb on-road manners. You still get the early morning flat spotting, but with this design it only takes a mile or two to shake them round again. In the dirt, the lug spacing and edge angles return great traction, while lateral reliefs in the shoulder lugs contribute to forward bite. The sidewalls of the Creepy Crawler are covered with raised, interlocking ribs that defend the air chamber from punctures while also adding traction when in contact with terrain. This makes them awesome in the rocks and phenomenal in mud, sand, and snow. Our biggest complaint with the Creepy Crawler is with ice traction, or lack thereof. You may as well strap roller skates to your axles, as the Creepy Crawlers’ large tread blocks inhibit control and leave you fighting to stay on course.

Maxxis Trepador
The Maxxis Trepador is an overbuilt tire with a massive carcass and a big weight penalty. Ample traction can be attained by dropping the air pressure below 8 psi in heavy rock. In deep snow and ice, the compounds lack of flexibility resulted in a somewhat lackluster performance. Sandy climbs require conservative throttle application because the stiff carcass tends to dig holes readily. We recommend beadlocks with this tire, as the robust sidewall construction and an exceptional 3,000lb load rating limit sidewall deflection. On the street, we did notice a slight amount of tread squirm, but only when pushing the limits in hard cornering. The noise level produced is pretty much the same as others in the category. If you want a summer tire that excels in desert terrain, the Maxxis Trepador could be the perfect answer.

Mickey Thompson Baja Claw Radial
We’re not sure how much longer this version of the Claw will be around now that the new Baja Claw TTC is in production. Featuring a proven tread design that is both directional and kinda noisy, the Baja Claw Radial is an excellent tire for mud bogging. The purposeful tread lugs offer excellent traction to propel the vehicle forward, but in reverse, the design lacks traction. The lugs extend past the shoulders and half-way down the sidewall, which makes them great for rutted hill climbs. However due to the thin 2-ply sidewalls, we don’t recommend them for sharp rocky trails. The lack of siping and overall tread design make it less than favorable in snow or icy conditions. When aired down, the Baja Claws work excellent in the sand...any very well nearly everywhere else..

Mickey Thompson MTZ
Among mud terrain tires, the Mickey Thompson MTZ is a versatile performer in the dirt. On-road, the pattern is louder than expected but still very comfortable in terms of ride quality. Like most Mickey Thompson designs, the MTZ includes Sidebiters that extend part-way down the sidewall. The thick, siped tread blocks provide exceptional grip in the rocks and we’ve found their performance in the mud to be outstanding as well. When negotiating thick slop, the MTZs didn’t require a lot of throttle application to clean out and pull willingly. Overall, the MTZ might not get a top score in any one terrain type, but they do everything better than average. If you don’t like compromising performance, the Mickey Thompson MTZ may be the tire for you. We recommend it to friends all the time.
