Cooper ST Maxx?

My 2012 is currently running on a set of BF Goodrich KO tires that are practically worn out at 32,000 miles. I have been looking at the Coopers and wondering if anyone has had experience good or bad with them.

Also other tire recommendations are greatly appreciated as well.

I love mine, all around best tire I've ever owned. Quiet, no flex while towing, still look new at 15k miles. Better than toyo m/t in snow, nearly the same in mud. Best of all way cheaper than most comparable tires.

Thanks for your contribution above. I have my second set of ST Maxx on my Landcruiser and am looking to fit them to my Ram

I don't want to hijack the thread, but I still love the ST Maxx

Just a few questions to you about the 35" tires and towing. What gear are you towing in?
What diff ratio?
Are you towing in 6th or does the transmission select lower gears?
What weights are you towing?
Do you find the engine and transmission copes well with the 8% increase in diameter over the standard?

I am trying to get a better understanding in my post https://www.cumminsforum.com/forum/ti...ger-tires.html

Well I plan on getting some 4.10's at some point right now I have 3.42's. It towed 16k in contruction equip just fine several times, just keep it in 5th and below. 6th is a cruising gear and not really got towing. I don't feel as if the eng or trans is struggling in any way, the eng can be pushed hard all day long anyways with little worry. The trans is fine also, gets a little warm at times but nothing major thanks to the 20 different coolers up front lol

I have the 295/70/R18 ST MAXX's and so far they are great. I have a little over 5,000 miles on them. Very good tire on and off road. I even keep mine aired at 72 PSI and they still provide a good comfortable ride.

Well it was between the Goodyear Duratrac and the Cooper's. I'm definately going with the Cooper's now. Better feedback from you guys on them. A little pricier than I thought they would be. $277.00 for an E rated 285/70R 17.

Make sure to check treaddepot.com and look at the prices. That same size is 242.00. Also your local discount tire will match the price of tread depot.

My old man runs ST MAXX 285/70r17 on his 08 mega and loves them. Great tread life, quiet and do great off road. Check out Discount Tire on Ebay, they seem to be very competitive and often have good rebates.
