    If you're looking for a long life and a quiet ride out of your all-terrain tire, then you should definitely consider a set of the Cooper Discoverer A/T3 tires. Now the Cooper here will be offered in sizes to fit your 17, 18, and 20-inch wheels in addition to tire heights ranging from 31 to 35-inches tall. Pricing, as always, will depend on your sizing here but expect to spend between $150 and $350 per tire. Now the A/T3 from Cooper is their slightly less aggressive all-terrain offering behind the Cooper S/T MAXX and will, therefore, prioritize on-road comfort, low noise, and maximum lifespan over everything else. Now with that said, guys, I don't want you to get confused or think that this is a one trick pony because it will certainly be up to the task of some light off-road duty as well. Now, your tread wear numbers are gonna reflect a tire that will deliver some long-term mileage and that is the case here at the A/T3 as you're looking at a 560 for treadwear along with a single A and B for traction and temp grades respectively. The tire has also been given the mud and snow stamping here which designates use for light snow or mud use. However, that shouldn't be confused with the three-peak mountain snowflake symbol which is gonna designate a tire worthy of severe snow service. But what do you say we revisit the treadwear and more specifically the lifespan here of the A/T3? And again, Cooper's gonna say 55,000 miles you can expect out of these puppies here with their light truck tire even more on some of their SUV options and that's gonna be awesome for guys looking for that long-term solution with their all-terrain tire as this will be one of your best bets in the category when looking for mileage. Now, moving to your tread design and listen, guys, I'll be the first to tell you the A/T3 here is certainly not going to deliver the most aggressive look in the category. So if you're shopping on appearance, the Discoverer here might just be one of the most pedestrian in the category. In fact, I'd say this thing is gonna fall somewhere between the Goodyear Wrangler SR-A and maybe even that Deegan 38 AT in regards to overall aggressiveness. But as most of us know, there's obviously more to the tire than just appearance but it is certainly worth mentioning. However, one of the good things about that mild tread pattern is the on-road noise or lack thereof as this thing will be extremely quiet on the highway as pointed out by a lot of our customer reviews and that's always a slippery slope when dealing with an all-terrain like this as they can get pretty noisy pretty quick. Now, Cooper does point out that the five-rib design here, let's count them off, 1, 2, 3, 4, 5, yes, they are correct, that's gonna help with performance and stability while on the road, coupled with the tread elements, which will help improve your handling as well. You are getting some pretty deep voids or grooves with the tires here and that's gonna help these things self-clear or clean off-road while also promoting better traction in heavy rain in addition to that heavy silica compound, which will be clutch when helping a tire like this maintain traction in the wet and in the cold. Cooper also pumped up the sidewall casing a little bit more here to prevent any damage while off-road as that's where a majority of your tire failures will occur when you're doing some off-roading. So if you're shopping for an all-terrain tire that will deliver a comfortable ride while on the road, very low noise, and maybe most importantly, a very long lifespan, then you'll wanna check out the Cooper A/T3 right here at
