Cooper Discoverer S/T Maxx

[Robert Bills]

Cooper S/T MAXX 255/85r16: $202 53lbs E-Rated 10-Ply
Maxxis Bighorn MT-762: $174 53lbs D-Rated 8-Ply

It seems fishy that the Bighorn is 2 less ply's yet the same weight. I found the weight on amazon so it might not be the most reputable source.

The weight of the Cooper Discoverer ST/Maxx LT255/85R16-E is 58 pounds, verified by Cooper in an email reply to my query about the actual weight of various sizes. The LT285/75R16 weighs 61 lbs.; the LT265/75R16 weighs 54 lbs.

I've had mine for a year and have nothing but good things to say about them. My only regret is not spending the extra money to get the LT255/85R16 size, but at the time buying 5 matching tires was not in the budget and I got a screaming deal on the LT265/75R16 size ($160/ea.):

Don't get Bighorns (also a Summit branded tire if you can find it) if you'll ever drive in snow.
They like mud and rocks but not street and snow.

You have to understand that he's stated his opinion EMPHATICALLY on numerous occasions. Scott was merely pointing that out.

Ditto on your end.

Regarding tire weights, here's a link to a spreadsheet that I put together with another member on thenewx.org:

Listed are some popular AT 32" and 33" sizes for 16" rims. It may be helpful for others here. FWIW I ended up going with the A/T3 from Cooper but the S/T Maxx was definitely a contender.

The AT 3 is a wonderful tire. and will serve 99 percent of the people on here perfectly.

I just purchased new tires a couple weeks ago. I had my heart set on the S/T Maxx but at $215 a tire, unmounted and unbalanced, I just couldn't do it. They were literally just out of my price range (I hate budgets). My friend told me they started running the BFG T/A KO2 on all of his work trucks. He works for a land and wildlife management group. Those trucks spend 8 hours every day off road. And I don't mean on dirt paths, I mean old overgrown or even nonexistant paths with cactus and mesquite thorns everywhere, granite, limestone, mud. You name it, they have to drive through and/or over it. He said they won't buy any other tire at this point. Much better traction than anything they have used before. Much more puncture resistant too.

So I gave in and bought the KO2 at $190 a piece, mounted and balanced. I have never had the S/T Maxx. And still want to get some. But I can't find anything wrong with the KO2. It grips on pavement, dry and wet. Dirt and gravel feel like pavement at 50 mph. Little to no slip on steep limestone inclines. But the best part, I don't hear them at 70 mph on the highway. In fact, my radio is now set to a lower volume then when I had my previous Discoverer LS tires that came on the vehicle when I bought it.

I will never bash Cooper as I have yet to be disappointed by them. And I still want to try the S/T Maxx. But I can't see a reason why I shouldn't get the KO2 from BFG again, when that time comes.

2 things.

1. FLAME SUIT ON!

2. That's exactly my point. The ST MAXX is a great tire, BUUUUUUTTTTTT, its not the be all end all that its made out to be. I am not BASHING Cooper, I have them on most of my rigs. Just the ST MAXX have flaws. I have used them, and know the tire well, UNLIKE most people talking about them. They have never used them, or have only used that tire and nothing else or have maybe 5000 miles on them. like some people I know here.

I think tire preference is such a personal thing, not only with the driver, but with the rig itself. Short arm/long arm, sky high lift or LCOG, do I like a plush ride or a "truck" feel...on and on. Otherwise, we'd all be running the same rubber! lol. I've got some experience with a few different tires, over a few rigs. Whatever you do, make sure YOU are happy with the performance of the tire. Nothing worse than hating the way the rubber acts on or off road. Totally takes away from the driving experience.

True'er words were never spoken. That's why as soon as I hear someone wants a good ride, and has a lightweight rig. I say don't use the ST MAXX, I get massively flamed for it. But its the truth, and sometimes the truth hurts.

You have a POINT!

I want the Cooper ST MAXX, but I may go with the BFG KO2 I can purchase BFG (32.8 ) at 194.00 vs Cooper( 33.1) at 210.00! But then I want a quiet tire with great protection, and saw a review were the ST Maxx is quieter then the old BFG by 4db's!

 

[kojackJKU]

NO chance on that. I have BFG, and I replaced my ST MAXX with them, and the BFG are quiet'er...if that's a word. You will be happy with them.

Well. I've had one set of ST Maxx's for 59,000 miles. They did get louder than the BFG AT near the end of their lifespan. I do not have a decibel meter so it is merely observational from an old metal heads worn out hearing point of view. I'm pretty darned sure they are as quiet as the BFG AT when both are brand new. I say this with a newish set (6500 ish miles) of ST Maxx's on the Tundra and a newish set of BFG AT's (7100 miles) on our Tacoma Baja.

I've also ran both tires (on the Tundra at different stages of its 226,000 miles) on roads wet and dry, snow, sand, mud, and gravel. The Maxx's may not be the end all tire of all things but it ranks up there in abilities, and in my opinion it surpasses the old standard set by the BFG AT in every way - which could explain the advent of the new BFG AT. For MY purposes and usage the ST Maxx is the tire to have. Your vehicle, usage, driving style, maintenance program, tolerance level, etc, may add up to a different result......

When the AT's on the Tacoma wear out it will be getting a set of Maxx's too.

Great summation, sir.

Why do you think BFG reinvented the KO?.....um I bet BFG had the Cooper ST Maxx and GY DuraTrac in their R&D department.

You can bet on that. Went back and forth with the KO2 and DuraTrac and finally went with the DT. Was worried about the thinner sidewall but so many people have used the DT in all kinds of conditions without any problems. I know a few had punctures. I'm more likely to be in mud or sand vs. rock crawling so went with the DT for my Ram 1500. Both have good reviews.
