Awesome tires for my 2012 ram dually!
Review for Cooper Discoverer S/T Maxx LT255/80R17 E/10PLY BSW originally posted on giga-tires.com
"These are really great tires. They are tall and skinny so that you can put them on a dually truck without needing a spacer on the back duals! They look great and are very quiet!. The tires do have a bit of turn break in them but not bad. Definitely recommend. Tire easy ships fast and have the best price I found on the internet. I would buy again!!"

Just a really great tire...
Review for Cooper Discoverer S/T Maxx LT235/80R17 E/10PLY BSW originally posted on giga-tires.com
"I have these tires on two 1-ton 4X4 Ram cab & chassis (flatbeds). They are fantastic tires. It's my understanding that Cooper classifies these as "Commercial Traction" tires. And, in that role, they are fantastic. They have the tread to get you out of most of what you'll get yourself into, but don't howl like an M/T (or wear even near as quickly). No matter what I've found myself in...sand, mud, wet pastures, silt, rutted Ranch roads and senderos, etc...these tires have handled it in stride. They also burn-up the highway miles without melting-away right before your eyes. If you find yourself wanting something with the best attributes of both an A/T and M/T, you should really take a serious look at these tires. Best thing of all? Made in the great U.S. of A."

Very happy with the tires.
Review for Cooper Discoverer S/T Maxx LT255/85R16 E/10PLY BSW originally posted on giga-tires.com
"This is my second set of Coopers. The previous set was a set of freebies I got from my brother, and they did so well in the short time I had them on my truck, I fidgeted Id give them a try, but new. The one thing I will add, is that I had them siped prior to installing them on my truck. My trucks two main purposes, are off roaring and towing. On road, theyve been awesome. Wet traction is great, theyre wearing beautifully. Off road, theyve been on par with previous tires Ive run, such as the Goodyear duratrac, but are handling abuse better."
