    These tires were given a very good review in the latest issue of 4wd Toyota Owner. I had already decided to purchase them but the article reinforced my decision and, coincidentally, I ordered them the same day I received the magazine.

    These are Cooper Discoverer ST Maxx LT285/75R16E tires installed on 16" x 8.5" wide Level 8 Guardian wheel. This will be the same size combo as on the white Discount Tire FJ. The wheels look great and the tires look to be a great "in-between" for those wanting something more aggressive than the typical AT and less aggressive than the typical MT tire. I think they will become very popular. I have no input yet on noise, smoothness, balance, handling or affect on mileage since they aren't installed yet.

    Tread compared to my old Nitto Terra Grappler LT285/70R17E tires. The St Maxx are much more aggressive. The height of the Coopers will settle down once I lower the pressure and get the FJ's weight on them.

    Here are some more pics after installation.

    For reference,
    - the old wheels were 17 x 9 American Racing 4 1/2" BS with -12 offset
    + new wheels are 16 x 8.5" 4 1/2" BS with -6 offset
    - the old tires were Nitto Terra Grappler LT285/70R17E
    + new tires are Cooper Discoverer ST Maxx LT285/75R16E

    Are you expecting total Earth devastation with no navigatable roads available?

    You guys are insane!

    I had regular Cooper STs in 285/70R17 on my old Dodge diesel. I tortured those tires, and they chunked out a little, but that was a heavy truck(7500#), and I wheeled the crap out of it. I thought they did pretty good as an in-between tire and I almost bought them for the taco, but I couldnt pass up the deal I got on my Toyos. Looking forward to see how they do for you.

    I've been running those tires (235/85/16) for a while now. They perform awesome in mud, super quiet on pavement, but snow and ice they are terrible. I've seen a dodge truck with bfg ats go up an icy hill which I couldn't even make it up.

    I understand what you are saying. I was once on a trip with my Nitto Terra Grapplers where I was the only one to not get stuck and everyone else was riding on BFG KM2 and BFG KO. These are a little more aggressive in-person than they appeared on-screen. However, I think they are reasonable and yet still quiet. I do most of my wheeling in Colorado and Utah so every trip is includes over 1200 miles of getting there and getting back on highways. Personally, I would never go full MT tread unless someone could guarantee they would be quiet and not affect my mileage.

    I think I found me a nice, new, inexpensive tire...
    Thanks for your show and tell. FJ looks nice.

    Here is a tire review

    Thanks for the link.

    I haven't had them on the trail yet but they feel great on the road. They ride smooth and quiet even at interstate speeds (though a tiny bit more noise than my Terra Grapplers) and track well. Each tire wheel combo weighed about eight pounds more than what they replaced but not sure how much of that was the wheel vs the tire). I think I lost about 1 mpg over the Nitto setup but the look is great and the slightly taller rubber should help on rough trails too.

    Sorry but no. The only snow or ice we've had so far has been during the holidays . . . and I was up in British Columbia skiing, snowshoeing and snowmobiling during that timeframe. :D

    I have these tires also, they are really quiet on the highway, have good traction in the mud and dirt, and I drive these tires year round and have had no problems on the snow packed roads or on ice.

    Like em, but decided to get the Duratracs instead a few days ago from Discount Tire. Why? The Coopers are a load E so too heavy, can't remember off top of my head but about 60lbs each?, the Duratracs in a load C are 45lbs. Big difference. Obviously the Coopers are stronger but the effects on mpgs outweigh that to me.

    That's really good to hear. I've been hearing mixed reviews for snow and ice and since I go snowboarding a lot, it's pretty important for me. What size do you run?
