Cooper STT PRO Review|All You Want To Know!

I wanted to write about my experiences about this tire so far for those interested in these tires! I recently drove up to Michigan and got to experience basically every type of weather/terrain with these tires after only having the on a few weeks. I also gathered input from others that have had these tires for a while now.

Dry Traction: These babies grip well on drive pavement for such an aggressive tire. I guess that has to do with coopers "Hybrid" design and the use of silica and a carbon black rubber.

Wet Traction: We got hit with alot of crazy rain here in GA. Got a chance to test of the wet traction. To my surprise, these things did amazingly well in wet roads, puddles and some flooded streets.

Deep Snow: I had to go to Michigan (my home state) recently and they got hammered with about 1-2 feet of snow. Driving up there on snow covered highways and not to mention driving on unplowed streets to get to my destination. And I must say....THESE TIRES ARE BAD***. I stayed in 2WD while I was on the snow covered HWY and switch to 4WD off HWY. Not once did I experience wheel slip, no traction control engaging, sliding . These babies ate through the snow like its been starving for weeks.

ICE: I have little experience on ice with these tires. But with the input of others that have these tires including my buddy in Canada that has had these since October, they do "OK" in ice. Obviously you want studded tires for ice anyways.

MUD: Well thanks to the rain in GA, my "secret" offroad spot was covered in Georgia's muddy clay. Again, these tires performed flawlessly and cleans well.

Road Noise: These tires are surprisingly quiet for such an aggressive tire. These are the most quietest M/T on the market. There is some "road noise", but not as loud as you would think. They are louder than the KO2's, but not much.

I made this chart based on my experiences and the experiences of others with the PRO's

 

Nice review man, those tires look great on your truck!

Think I'm gonna go with the ST Maxx myself. Seems like you can't go wrong with any of these newer Cooper tires.

 

Your right! The ST Maxx are great tires as well. I personally never owned them as this is my first Cooper purhcase, but Ive heard amazing things about the ST Maxx.

 

Thanks will add that to the list!

 

Beautiful man , I have same truck glad I saw these.on stock rims...love the white lettering...what size did you get i.just looked online and.they are showing 305 or 325 for 18"?? Thanks

 

I have 305/70/18 (35"). I originally was going with the 295/70/18 but cooper has these on national back order which is why its not showing on the site. I believe a few companies have some in stock though.

You wont regret it!

 

I have the S/T Maxx and LOVE them. One thing I like different about the STT PRO is more space between nubs. I do get enough small rocks stuck in these Maxx's. Still love them though.

 

Great review, thanks man. I just got mine delivered yesterday 295/60/20's. Just waiting on my lift to get here and I can put them on..

 

What kind of mileage are you getting with these tires? Right now im stuck between these and the Toyo R/T.

 

I just took all road trip and only got 12.5 average Hwy. That's with a 3" front, 2" rear and 35" tires. Smaller sizes will yield better gas mileage.

 

I should've been more specific. I'm talking about tread life.

 

I got about 25k miles on the tires and still about 70% tread left. Seems to be wearing really good

 

Thats pretty impressive

 

I think I may go with these this weekend instead of going with the nitto ridge grapplers I was going with. Still going to be running stock wheels same as you with a 3" front and 1" back lift, was there any trimming you had to do? Also I'm assuming your running wheel spacers?

 

Go wit the 295's. Im running 1 1/4 spacers and still needed to trim the skid plate and move the front bumper 1" forward. It still rubs in full lock reverse.

 

Thank you sir! Truck looks spot on man.

 

Thanks!

 

They "look louder" than the RG

 

Yeah I'm sure they will be a bit louder.

 

Its louder that the grapplers, but not as loud as most Mud tires. Grapplers are AT tire so it will definitely be quieter. But overall, it doesnt bother me at all. Though they do tend to get slightly louder as the tread gets lower.

 

Those look great, what size would be good without a lift ?

 

Mine have gotten a bit louder as they have worn down. They are not as loud as the Nitto Trail Grappler MT's when new but when worn down they are louder.

 

Thanks man!!! I am debating these or the DuraTrac’s

 

Great write up! Do you mind me asking the tire size/lift on the truck in original post?
