Cooper STT Pro in 285/65/18

mkenum79 · September 23, 2016

Well need a set of tires before hunting season and winter hits here and I've settled on the Copper STT Pro. I can get a set for a hair over $1200 out the door. Thought about ordering them from Discount Tire Direct, but by the time I pay install fees and have to pay for rotations and service on down the road, it would be cheaper to go direct with the installer. I do probably a 50/50 mix of on and off road driving, plus need some added traction on the deer lease from time to time. I've searched the forums and haven't found a whole lot of feedback on these tires from people who are running them, mostly just comments on the looks and folks waiting on theirs to wear out before they buy them. So, anyone running these or have any issues with them?

I put over 50 k on some cooper discoverer at3s in my old 06 sierra and am running cooper discoverer st maxx on my new 14 Silverado z71. I purchased the at3s from discount tire direct through eBay. I had them rotated and maintained (I am not sure if this is policy at all or any stores) at discount tire and they never charged me anything to do so. They even fixed two flats on the same tire for free. I tipped them almost every time because I appreciated the service but they were happy to take care of me. I loved those tires but didn't do much off roading. The st Maxxs on my 14 z71 were pretty beat up from the previous owner due to a lot of off-roading and badly worn shocks and struts. I replaced the rear shocks and the rear tires are evening out pretty good. I hope something here helps

Ordered my set of STT Pros today on lunch. Should be here tomorrow. Plan on getting them mounted up Wednesday. I'm pumped to see how it changes the look of the rig. Pics to follow.

Well got the Coopers installed this morning. I am ecstatic at how much it changed the look of the truck. Looks like it's balls finally dropped. To me the size fills the wheel wells appropriately, and the width is enough to give it a proper stance on the OEM wheel. They do have a slight bit of hum, which is expected of a mud tire, but it's not the loudest I have heard. Maybe once they are broken in a little they may quiet down some. Enjoy the pics....
