Outstanding value in an E load tire
Stock replacement size for GMC Sierra 2500HD, 245-75R-16. these are 10ply E rated tires and by far the least expensive option I found. The deliver and prepay mounting service is good or bad depending on whoโs local to you, my experience was just Ok. The tires ride fine, are quiet, seem like above average quality, US made (coopers are produced all over the world now) Time will tell how they hold up but so far so good.

Good Price
I purchased 4, LT245/75R16 COOPER HT3. Tires were delivered quickly to one of three offered tire install stores. One of the four had access rubber flaps hanging off the side bead. Makes me question manufacturers quality control. A fraction of the price for the same tires locally.

Good performance
I bought this tire to replace a dry rotted spare. This tire matches the other six tires on my Dodge dually. I have had good performance out of these tires and I would recommend them. Note that I have never used them on snow or ice except for one time in a light dusting, so I can't speak to performance in wintery conditions. I have run them at a sustained 70 mph in mountains and flat lands while towing. I do not find them noisy and I am pleased overall.

Great tire and amazing connection with Mr. tire
Awesome tire! Heavy duty for an amazing price. And the $99 4 wheel installation was legit. Mr. tire did a great job and In-N-Out and flawless process.
