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%.

Rides smooth, slight hum while moving nothing major. Balanced out amazing. Great grip in rain and offroad. No complaints from me!

Awesome performing truck tire!
Great tires in rain, mud and sand here in florida. Much quieter on pavement than i thought they would be. Very aggressive tread, i hope they wear slowly.. Update, 4.29.2018 Have been daily driving on these for 1.5 years! They wear slow, balance and rotate great still. Noise is very low at any speed. Still look amazing and my Tundra has never been stuck....ever WILL replace with exact same tire if they ever wear down enough to replace. Have well over 70% tread left

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.

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 haven’t done a tire rotation yet. Overall good tire

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!
