Cooper AT3 vs General Grabber AT2 vs BFG AT

I want to learn about the Cooper AT3. I just heard of this tire. I am excited that it comes in 30x9.5R15.

What are the pros and cons of this tire?

How does it perform in various conditions on and off road?

How does it compare to General Grabber AT2 and BFG AT?

Note: I am referring to the new, improved, updated version of General Grabber AT2 that was released several months ago.

I have the Coopers on mine, and I love them. They do good in sand for being skinny and running road pressures. Nice and quiet on the road, great on wet roads, good (for an AT) in the mud, and climb sandy and packed clay good too. Don't' know how they do in the snow and ice though. I did have the BFG AT KO's on a pickup when I was up in Alaska, and loved them on the snow and ice. Never ran the Generals though.

All 3 tires are rated as Winter traction devices and excellent on snow and ice.

The Cooper AT3 has silica in tread and is reputed to perform even better than BFG AT on Winter roads.

The Grabber AT2 has softer tread rubber and lots of sipes and performs even better than BFG AT on Winter roads.

Grabber AT2 has super strong sidewalls and is an extra tough tire. It won't get flats. However, this makes it ride rough.

For ride quality (soft ride) tge BFG AT and Cooper AT3 are excellent.

The BFG AT and Grabber AT2 pick up a lot of gravel. The BFG sometimes retains the gravel until you pry it out with a screw driver. The Grabber AT2 picks up gravel and then promptly flings it out at high speed, which is annoying but harmless if you have mud flaps to protext your rocker panels and doors.

The Cooper AT3 is designed to NOT pick up gravel.

I think the Grabber AT2 is the best AT for hardcore off road activities, and the BFG AT and Cooper AT3 are the most civilized on highway and on gravel roads. I think the Cooper AT3 is the best combination of on and off road manners and capabilities.

I have owned 2 sets of BFG AT, and I recently purchased a set of the new, improved, updated Grabber AT2. I miss the BFG AT soft ride quality, but I like the Grabber AT2 off road prowess.

I wish I had bought Cooper AT3 because it would be a nice compromise. It is an excellent middle-medium choice between the other two. IMO

I just stumbled on this thread and hope to update it with my limited data on the Cooper Discoverer AT3 tires in 265/70/R16 (SUV application) I just had installed:






I replaced the BFGoodrich All-Terrain T/A KO that the PO already had when I bought my Jeep two years ago. They had worn down to the wear bars and I rarely hits any trails of note as she pretty much only sees the streets/hwy. I had no complaints about the BFGs which rode good, were decently quiet (the wife dislikes the hum tho) and they're damn expensive! I wanted to try a more modern AT and read countless threads and forums on the different types of AT tires, but most didn't give enough info for a real good comparison as [U]everyone[U] drives their Jeep differently in all kinds of terrain and conditions. I'm no exception either folks!

My Jeep is a 2wd (gasp) with a modest 2" BB that spends most of her time navigating in the city and occasional forays down a tank trail or two with detours around gasp x2 the few mud holes I encounter here in AZ!

Back on track, coming from worn noisy tires, these Cooper AT3 tires are riding well, quiet & plush, but you'd expect that from new tires. I have received a few compliments as they're not too common a sight on lifted vehicles here in my AO.

One gent stopped walking by in the commissary parking lot to chat about them as he was looking to put new shoes on his 2006 Rubicon and liked the AT3 looks. He was impressed to hear about their 55K warranty, 560 TW etc, and the only were +/- $160 depending on the size.

I'll update my historical data on here as time goes on as I'm keeping a journal on these tires so I can contribute 'factual' input down the line instead the un-useful "I love my AT3s because I just spent $800 on new tires and I'll never go back to insert brand-name" posts.

I'm totally sold on Cooper AT3. Will get some soon on my XJ. Might even put them on my Buick Park Ave full size luxury car too (since available in size that fits, quiet, good ride, and good price.

Edited in Later: Still like Cooper AT3, but now like Hercules AT2 best.

Basically same tire IMO, but different tread pattern. Both same or comparable in all ways except two, IMO.

Cooper AT3 is excellent in mud (for an AT) while Hercules AT2 is excellent on ice (for an AT).

That's probably because Cooper AT3 has larger voids and Hercules AT2 has twice as many sipes.

Ice traction is more important to me than mud traction. Both tires are good on snow, but Hercules better on packed snow.

That is based on my experiences with Cooper and reports I've read on both Cooper and Hercules.

General AT2 and BFG KO are old technology. Older than a lot of members of this forum. The General wears like iron and is a good, dependable, rugged tire. It does well in dirt and on pavement. It's not terrible in rain. But it sucks in snow and mud. It'll get you no where in those terrains. The Cooper AT3 is brand new technology. Silica compound, circumferential grooves, stepped siping, terraced tread blocks, the whole nine yards. It will out perform any All-Terrain tire on the market and it's less expensive to buy also.

The Hercules Terra-Trac AT2 is the cousin of the Cooper, and it has a slightly better tread design and it is often times even less expensive, but if you can't find it go with the Cooper. Better traction, better price, better warranty, better fuel economy. Why would you buy another tire?

nowhere = 50 miles a day in 6-8" of snow/ice with no slipping.

You must have found the set that has magical unicorns molded into the sidewalls. The entire internet is loaded with complaints about mud/snow performance with these interlocked tread pattern tires. And I have run BFGs and Generals both more than once and they sucked in the snow. They wouldn't even grab taking turns at low speed in 2" of powder. Just awful.

General Grabber AT2 are Winter rated and widely reviewed to be good on snow and ice. I never had opportunity to try mine on much.

The thing I didn't like about GGAT2 was the extremely rough ride. That's why I switched to Cooper AT3.

The thing I liked best about GGAT2 was they are large for a 30 x 9.5 R15. Also large in 31 x 10.5 5R15. And they're exceptionally light too.

Charley3: Now that you have had them for a while, what do you like and dislike about the Discoverer? Particularly off road.

The Discoverer AT3 is a great all around tire and has an exceptionally comfortable ride for a C rated off road tire. It's very capable in mud (for an AT), but slick on ice (not enough sipes). Good on snow and all else.

If you don't get much ice, get Cooper AT3. If you do get frequent ice, get Hercules AT2 or Hankook ATM. The Hercules AT2 has same comfy ride as Cooper AT3.

IMO

P.S. - the extra sipes on Hercules AT2 and Hank ATM also give them a slight advantage on wet pavement during hard cornering or panic stops.

During normal driving on wet pavement you wouldn't notice a difference between Cooper AT3 vs Hercules AT2 or Hankook ATM.

On dry pavement, I think the Cooper AT3 would handle the best of those 3 because less sipes is an advantage on dry pavement during hard cornering or panic stop. Less sipes means less tread squirm (more stable tread blocks).

Those are the special ordered AT2s with magic unicorn shoulder lugs.
