Comments : Rumble and tumble boys, these kick ass tires have your back! From the hard work of pulling someone out of a ditch, to playtime in the overland, Cooper Discoverer STT PRO's have your traction and are built for the job.
Comments : Ive had these for a few weeks, they sound like a swarm of angry Bees, but its tolerable. Ive taken them off-roading twice, took everything I could throw at them, chewed it up and spat it out!If I may, Ill post again early spring with how they do in Albertan winter.
Comments : Very quiet and handles the road excellent for a mud tire. Also has a more aggressive look in person than in pictures. Would buy again.
Comments : So far I've put 20,000 miles on mine rotate every oil change 5,000 miles. I'm running about 36psi when cold when tires warm up it's about 38psi to 39psi and on a hot day 40 psi to 41 psi my best mpg have been 21mpg with this tire size and psi
