Anyone on here running cooper st maxx 285/70-17? Thoughts

I have 265/70/17 ST Maxx. With mine being slightly narrower and smaller my experience may not be exactly like a 285.
First off they only come in an E rating, and therefore are very heavy. Fuel economy is slightly worse and the ride firmed up a bit. I actually like the stiffer ride, and it improved the nose dive a bit. I find them a nice compromise between a mud terrain and an all terrain, they look great on the truck and in the bigger size they would look even better. As for performance I have had them in both summer and (Canadian) winter. So far they have been great. Deadly grip on gravel roads and mud, a little sketchy on ice, but great on snow. Both packed and loose. They are lasting really well. I have had them for almost a year and they have lost almost no tread. Overall I would say they are a great tire. My only other experience with all terrains is BFG all terrains, and I prefer the St maxx. Hope that helps, I can also put some pics up with them on the truck if it will help.
 
There were none available nationwide when I was looking at them, and wound up picking up the Cooper STT instead. Also the ST Maxx in 285/70/17 are actually 3 pounds heavier than the beefier lugged STT's.
 
Very good all around tire. I have had them on for over a year/10k miles and barely showing signs of wear.

285's....... There is a little power loss and a drop in mpg. This is fine with me because it is a 4x4 off road vehicle not a race car. The traction and security when in the back country is payback enough to compensate for power loss and mpg.
 
I have flirted with this tire several times. I have the 285 DuraTracs for highway use and kept my 275 MT/Rs to use offroad. For the kind of trails I seem to always find - hard, rocky, trails - I think the S/T Maxx is the best overall option for trucks running one tire year round. But it is very heavy - 61 pounds in 285 versus 53 on the DuraTrac - and the road reviews are not great. But I would have tons more confidence in it offroad than I do my DuraTracs. The DTs provide excellent traction but the sidewalls are super soft. Push on a deflated DuraTrac next to an MT/R and you see a huge difference.

I'm still holding hope Goodyear makes a kevlar reinforced DuraTrac so I can be a one tire set guy. Probably wishful thinking though, as that would really diminish their MT/R sales.
 
Instead of starting a new thread I decided to resurrect this one. Any updates from previous owners or experiences from new owners with this tire? I had intended on going with siped km2s but I'm thinking I might get more life out of the coopers and they're considerably less expensive. In 285/70r17 the E-rated ST-Maxx weighs 1-pound less than the D-rated KM2, according to treaddepo.com's stats. This, and reviews from truck forums, leads me to believe it might be a relatively "soft" E-rated tire, which would be good for our 4Runners. Because it's still a relatively new tire there aren't a whole lot of reviews out on them. I'm specifically interested in hearing about the ST-Maxx, lets not turn this into a duratrac vs toyo vs ect..respectfully. Thanks everyone, hopefully we can get some more first-hand experiences with this tire.

How do you like your STTs? Whats the weight on them?
 
The STT's look great, have spectacular traction, and are pretty loud on the road. I like them.

I don't recall the weight exactly, just that they were actually lighter than the ST MAXX version. They're not as heavy as Nitto's.

I've got 265s, love the way they look, beefy and wider than stock in a 265, and they definitely feel planted. There is a bit of road noise, but I plan on putting in some sound deadening material in the Spring. With the added weight vs stockers, it does feel like it takes a bit more on the pedal to get going and during braking. Overall, I'm satisfied, just wish I would've went with 285s...
 
I have been running the 265s for a year plus, two summers of off-roading. I am really happy with them, they do have a bit of road noise but i think they are a great compromise for daily driving and being really capable off road.
