Cooper Tire Purchase

Good

Had these Coopers installed this morning. Drove back home on a mix of  interstate and Ohio back roads. It snowed last night so some roads were covered with about 1" of snow and others were dry. Tires handled great. Had a tad more road noise than the Mastercrafts they replaced (you can see them in bed in one of the pictures) but I'm not driving a 1 ton diesel because of the smooth quiet ride it has. As soon as I got home I drove around one of my fields and the tires done great. They had 3 other E rated AT's in stock so I was able to directly compare them. These and the Toyo At's were the most aggressive looking tread and looked like both weighted heavily towards off-road ability. The Wildpeak At 4 and Pirelli scorpion AT plus looked less aggressive and more weighted towards on road manners. These Coopers had the most aggressive sidewall biters out of them all and spacing between lugs that was atleast as wide as the Toyos and wider than the other two. These coopers were the least expensive. Cooper and Toyo were the only two Made in USA. They all had the 3peak snow designation. Tread depth looked the same between the Wildpeak, Toyo and Cooper and looked more than the Pirelli. None of these tires are Super Swamper aggressive but they did well in my snowy field and I believe they would do well on the job site or going down an abandoned coal mine road in Southern West Virginia. So if  you're looking for a tire with good road characteristics and still pretty aggressive off-road these Coopers are what you're looking for.

aggressive AT tire

Only had them a month ride is good for a 10 ply , a little road noise but so far the a good performance

Copper

When I inquired about these tires, I asked if new bolt in metal valve stems could be installed when the tires were mounted.  I was told that it would be no problem.  I purchased the tires and scheduled the installation.  When I arrived at the installation appointment, I was told that Sam's did not have bolt in valve stems and wouldn't try to get the them.  I cancelled the order and purchased the same tires at another tire store that could provide the valve stems that I required.

I believe that it is poor customer service to agree to a customer's request and then refuse it after the customer has taken their time to show up for their scheduled appointment. I have purchased numerous sets of tires from Sam's in the past, but will be very hesitant to do so in the future.

Poor Service

Have had these tires back in Sam's Automotive to be balanced 3 times. The 3rd time they replaced one of the tires that would not balance for a small fee. Tires had less than 5000 miles on them. I still have at least one more that's badly out of balance. Service Technician said this is common with the larger Cooper Tires. Would have been good to know before I purchased them. Have to schedule another appointment and argue with them again that there's another balance issue.

Never buy Cooper Stronghold for  3/4 ton trucks

Tires do not last pulling heavy loads wear out very quick
