Great buy!
Cooper has some good tires in their lineup, might not have the ultimate grip of the stock tires which is a fair tradeoff if your needs dictate other aspects as more important and for the price if you are happy then a superb deal for you.
--------------------
I have Chinese made, Cooper owned factory, tires on my 43' toyhauler, best trailer tires I have ever had or heard of. Far better than the close to $500 each Goodyears many think at the best, quite a step above them actually. When I am going down the highway with my wonderful wife, Akita, Wolfhound, built FiST, 62 ft long, $$$$$ rig, I am so glad I have the best tires I can get. I have a newer Michelin on the truck as they are the best for it and the A/S 3 for cold weather, etc for the FiST but the cooper owned trailer tires are the only ones I will use and they were $225 each which is low for the best 12 ply tire made.
Tire brands are something you have to really look into carefully, some lower cost tires are better than more expensive brands, as in the trailer tires, Cooper is the best I know of. Then there was the Michelin tires that were brand new on our V8 4Runner, I got rid of them asap, sloppy handling was the reason and went to Falcon 285/20 sport truck tires that are dang fine for everything all year and handle amazingly well in the canyons, paved, dirt, snow, whatever.

Pick tires by needs first then buy the best ones that fit your budget or you get the best deal on, as long as really good tires, they are the single most important part on your vehicle.
