Show Off Your Cooper STT Pros

From my experience with past stt pros, they are quite loud. ive ran the rugged treks on another vehicle and they are silent. You will lose a couple mpg, more if you’re not tuned as the gear hunting will be even worse.

 

So on the other end of the spectrum then. How well will my SL rated rugged treks do off-road in rocky terrain in Arizona? Should I be concerned that my sidewalks aren’t strong enough?

 

315's are on!

 

@The Field Archer great looking rig! Red and black are my favorite color! Very rugged looking.

 

Thank you!

One of the guys in our group a couple weeks ago had a FJ with 37" STT Pros that performed awesome! FJ was red and black too!

 

Go E, SL are only 3 ply and E are 10 ply. Airing down a lil is a good idea too. Having lived in Phx, and hitting the desert, SL get punctured easily on jagged rocks it’s not the side walls you have to worry about, it’s more with the tread thickness. SL is more for local on road or light trails which are smoother if that makes sense.

 

It does but the rugged treks in sl have a deep aggressive tread on them even though they are sl rated.

 

im looking to go from a 255/85/16 cooper discoverer st maxx to 285/75/16 cooper stt pro.. of those that have the 285s and are 2nd gens how many of you had to do the CMC? im trying to figure out if i should just go ahead and bite the bullet or wait and see how it turns out

 

Why did @Discount Tire (America’s tire where I’m at) stop selling these for size 37x12.50r17?

 

They are discontinued now I think
I had to get bf goodrich KM3 and holy crap they are dog shit. Those Coopers were the best tires ive ever had its a shame ): If you find a good alternative let me know I want these KM3 off asap.

 

Dang, I just checked other sizes as well, you’re correct, they discontinued them.

 

265/70 just installed. Major upgrade over the Terra Grappler G2s that my truck came with.
