Truck needs new tires soon... It's got BFG Long trail radials now... Think I want to see if the cooper shop down the road from me carries these :D We always get tires there, they hook us up nicely.

Looks like a decent tire. My mom had Coopers on her Explorer a few years back and liked them!

 

I loved the Cooper's I had on my ranger. A couple members here have them.

 

I have the Cooper ST MAXX's on my ranger and like them alot. I think they're load range E or whatever, the guy said they were made for 3/4 ton, but ive probably put about 20k on them and they still look new and barely look worn. They're pretty nice on the highway but are awesome in mud and really good in snow conditions. My old roommate had those same tires (A/T3) in 285's on his cummins and really liked them for driving across the US and as his road tires. His other tires were 37's with Pro comp xterrains though

 

yeah we normally have coop's on our 3 vehicles. maybe I'll make a deal with my dad, he buys 2 I buy 2.

 

If they're anything like the ATRs were, they're good tires. The ATRs worked well in almost any condition (well besides 2ft of snow or mud) and got good treadlife.

 

I just purchased some Cooper Discoverer ST's and I have only but good things to say about them! I've only put about 1,000 miles on them but the traction in anything is great, especially in the rain. I looked into the AT3's first but turned them down to being a load range E. The ST's are a load range D.

If you go to the AT3's just watch tire pressure and play around with it until you can find a good medium between a good ride but not too soft that the tires are underflated.

 

I'll keep that in mind, thanks. Now I feel like I should know this, but what's the difference from E-D?

 

No problem man. Load ranges used to be measured in plies. Like a D rated tire would have 8 plies of rubber. This can cause high heat thus tire companies changed how they made tires with new compounds stiffer rubber, nylon vs steel belts etc instead of using several plies of rubber.

Load range is the specific weight one tire can hold when properly inflated. A D or E are heavier tires due to heavier rubber and materials that make them. That's why most people run those load ranges on heavy trucks ie an F-250/350. Less ratings like a C load rating is better to use on a Ranger due to the "softer" rubber and compounds that it is made of. However all over this site people use D and E load rated tires and just play with the tire pressure to get a good ride. My Cooper's in a 285/75/16 are a load range D and they ride great now that I have found a good tire pressure to leave them at. Good luck on finding some tires! It's always a challenge for me lol.

 

Oh ok that makes sense then... Sounds like D or E should hold up longer than a C because of the heavier grade. I don't even know if I will get these, I just stumbled on them and thought they'd be awesome.

 

The ply of the tire changes. Usually the rubber compounds remain the same. Load range C's are 6ply, D's 8ply and E's 10ply. You can usually find Load range C's in whatever size you're looking for.

 

Ok. Haha thanks guys, I'm still a bit new with this. Tires aren't really something I'm good with.

 

Sorry to bring up an old thread, but my dad bought tires for blue today, and he ended up buying the AT/3's. I never told him about them and I wasn't there when he ordered them. I guess semi-great minds think alike.

 

Got mine today 265/75/16 on a stock 2002. I also have 35 STT's on my 03 Rubicon

 

I have the AT3's on mine. Good tire. Mine are about 10 months old, tread looks good, about 12k miles on 'em so far. I have the stock size at load range E. Pretty heavy duty. all in all, I'm digging 'em.

 

We're happy with 'em so far. I'm excited to see what they'll do in some snow. We're having yet another unusally warm winter this year.

 

Got the M+S's in 225/75R16 going onto my Escape and have the S/T's in 285/75R16 on my Jeep. Good tires for the money.
