Cooper sst tires are legit.
I always used to use Dick Cepek tires until I bought my first set of coopers 2 years back. Now I always use Coopers on all 3 of my trucks.The SST,s are not noisy and handle perfectly on my f250 super duty , I love them for all my driving needs. They look aggressively awesome 10/10

Great tires
These are really great tires, great traction, they wear great, they will make your vehicle stand out from the rest. They are a bit pricey. You get what you pay for though. They are a bit noisy on the highway, but the benefits out way a little noise. I recommend these tires 100%.

Great tire so far
Great tire so far. Tread wear is good so far. I drove from Colorado to PA and back on these at high speeds and no issues. They make noise but they are not that loud. If tire noise bothers you, MT tires are probably not for you because these are the same (noise wise) as Cooper S/T Maxx's I have had on my truck prior to them. Love these tires, EXCEPT for they do kick up a lot more stones/debris and will chip your body paint around the tires. So get some mud flaps or 3M body protection film. I am going to get some 3M body protection film custom cut for the body style of my truck in these areas and continue running these tires.

30,000 mile review
I travel 60-70k miles a year. I've ran BFG's KO2's for many years, averaging around 80k before needing new ones. I've got 30k on these so far and I'm very pleased. They look aggressive and I like the stance of my truck better than I did with the BFG's. They balanced out easily & have a good ride with minimal road noise. They handle well & have good grip in the rain. If they continue to hold up for the next 50k as well as they have the first 30k, I'll have to consider making a permanent change.(After I try out the KO3's) As of right now I'm a fan!

Good tires
These tires are more aggressive in person than the picture. They did have a slight more road noise than my previous tire (Nitto mud Grapplers), but nothing over bearing. I run these on a 2011 Chevy Silverado 2500 HD. I ran these in 4WD running thru my pasture and they grip very well in mud and/or dirt. A lot my my driving is on pavement and the tires are holding up well but I am only at approximately 7k miles on them and havenโt done a tire rotation yet. Overall good tire

3 Years and 50k Miles Later!
3 Years and 50k Miles Later! Cause lets be honest that is what you want to know.I purchased a set of 4 - 295/70R18 On March 1st 2018 and they were installed March 5th the same year.Pros -*Amazing off road tires, especially if you air them down. They clean out better then tires 2x their price. Mud, Snow, Sand they have held up amazingly.* Road noise very limited the first couple years I have had less aggressive tires make way more noise when going down the highway.* Wear and Tare they have held up great. 50k miles 3 years and still have a good amount of tread on them. They actually shocked me usually 2 years is about all I get out of a really aggressive MT tire. These blew buy this expectation laughing. I actually just ordered a new set cause these are in that butter zone where I can make some cash back on resell.* Mount and Balancing. They mounted and balanced pretty easily for an aggressive MT tire. The balance line on the tire was pretty true and the Tech did not have to muck with them to much. Unlike some other MT's I have had that the Tech almost quit on me trying to get them balanced.Cons -* Road Noise 2.5 years - when they cut through about half the tread that noise starts to shine through the stippling in the tire that helps reduce this noise is pretty much gone at about half tire life and well yeah they start to howl. Now into year 3 and yeah they are border line obnoxious. Some people don't care about this howl, I tend to only cause I haul a boat and put on a lot of highway miles. However 2.5 years before they started howling is a .5 year longer then I thought the tires would last in whole.* Packed Snow and Ice - I am in ND land of the frozen nothingness. While Mud, Fresh Snow, and Sand mean nothing to these tires the lack of surface area has them singing a different tune. Packed Snow and Ice is a bit of a challenge for these tires. If you live in the north it is something you should note. However you should also know that most MT tires that have super aggressive tread suffer from this as it is a lack of surface area issue.* Rocks - again this is a con for all aggressive tires but these seem to be especially good at picking up rocks and stones and holding on to them for dear life.All in all I love these tires and like I said just ordered a new set. If you like a good looking tire that will hold up on the road and not leave you stranded off road. These are amazing tires.
