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
Comments : Great looking tire and the road noise isn't bad at all. Off road it runs like a champ and driving in the rain hasn't been an issue either...great tire for the money!
Comments : Great tire looks good but white letters are starting to fade kinda bummed about that have put 2 k kms on showing no signes of wear at all great traction in mud sand gravel have done some hill climbs in northern Ontario and hit some mud hopes too 210 HP v6 4.0 sohc with air intake 3.55 gears and true duel exhaust with glass packs turns then in4wd high but getting 4.10's
