So much quieter and smoother. Like going from sleeping on a plank to a mattress.From the old S/T to the STT PRO is a nice upgrade.![]()

2) Recent comments (increasing in frequency) out on the internet are starting to complain about the Cooper Discovery STT Pro and how it wears and that it won't stay balanced (my exact same issues with my current tires).

Multiple sites - Jeep forums, Full-size Truck forums, Cummins forums, the comments are starting to show up.
o.k., to summarize: not even one single link, and you don't own the stt pro.
I have them on my Ford F-250 SD. I just rotated for the second time at 10,000 miles. Now, I have a little wobble at 60-62 mph. No biggie, but if it stays after the next rotation, I'll re-balance. Seems like maybe it's just a one tire issue. These tires are great on the ranch with the rocks and mud. Couldn't be happier with that side. The 50 miles they spend on pavement everyday are a little noisy, and now, a little wobbly compared to the stock Michelins they replaced. All and all, I'm a happy camper.
