Overall the Toyo Open Country MT offers a better gripping on dry roads, but the tire is very confusing on wet, as its not able to provide a good enough lateral stability. The Nitto Trail Grappler is also same here, though it does better with hydroplaning. On the other hand, if talk off road, things are seen better on Nitto Trail Grappler, as it offer a superior self cleaning tread.
Continental TerrainContact AT is although an All Terrain tire, it's better on roads compared to rougher tracks. In fact, the tire is one of the quietest you can have, it also offers best traction values on both wet and dry roads. It's very quiet, where it's decibels even meet with some passenger tires out there. Same goes for it's wet and dry traction, where it does great in all key areas, grip, handling, steering response and stability, hydroplaning, you name it. But note that don't expect these tires to provide better fuel efficiency, as with more grip, comes more rolling resistance.
BF Goodrich is better suited overall for roads, in terms of traction, noise, and fuel efficiency (though wet traction of the tire is not that impressive). Yokohama X AT on the other side, does things better with hydroplaning and has upper hand off road especially on mud, where both tires are good enough for rocks and sand. On snow, the tire is better suited for deeper terrains despite not having 3pmsf rating, whereas KO2 offers better friction on packed snow.
Overall I can say both tires are very impressive, but still I would rate the Discoverer STT Pro for better traction on rocks and BF Goodrich KM3 for overall all rounder tire which is great on wet roads even (well compared to M/Ts), the tire is not good overall.
The Patriot RT and RT+ and the same as Renegade RT and RT+, and the only differences is in their sizes, they did this for marketing reasons. Nonetheless, the tire is still underrated given it's performance. It's 3PMSF rating and it's performance on deep snow is simply epic. The tire is also pretty well optimized for on road use, where although noise is an issue, these tires do great in rest of the sections. But know with snowy performance, the tire's rubber has to be kept softer, so this also causes tread wear issues a little bit as well.
Goodyear Workhorse AT is a good all rounder tire, which offers one of the best steering response on highways. This has to do with it's being so light. The heaviest size of the tire is just above 50 lbs, most of the AT tires start from there. So with that the tire does great on sand, and climbing rocks (where gravity doesn't work against it too much). And at the same time the biters everywhere help this tire with traction further. These several biters also earn this tire with 3 peak mountain snowflake rating symbol.
So overall the BFG Trail Terrain is a very nice on road oriented all terrain tire for sure. It mostly shines in terms of fuel economy, overall ride comfort and winter performance. Puls its also great in terms of handling on dry roads in particular, and off road in gravel. Though it needs some help on wet roads for sure.
The Goodyear Wrangler MTR is a very powerful off road tire that does not disappoint on any kind of rugged terrain. And its a surprise to see that these tire s are still able to perform okay on dry roads. But they are very poor on wet roads, so it's advice not to run them with traction control off. Also these tires are no so good with fuel efficiency and the tread wear, and same goes for icy roads and hard packed snow. But despite not having been rated with 3 peak mountain snowflake rating, these tires are still capable of taking on to deeper snow.
Overall the Toyo Open Country RT is overall great option for someone who likes to stay on roads with a hybrid tire, and yes who can compromise a little on it's wet grip. A pro tip though, if you have to run these tires in rainy season, just lower down the tire pressure it's going to help with the traction, also always drive these tires in rain with traction control ON at all times. The tire offers a great wear resistance, and it very robust with 3 ply strong sidewalls which can take on pretty much any kind of sharp close encounters.
The Federal Couragia M/T is a very powerful off road tire that does not disappoint on any kind of rugged terrain. And its a surprise to see that these tire s are still able to perform okay on dry roads. But they are very poor on wet roads, so it's advice not to run them with traction control off. Also these tires are no so good with fuel efficiency and the tread wear, and same goes for icy roads and hard packed snow. But despite not having been rated with 3 peak mountain snowflake rating, these tires are still capable of taking on to deeper snow.
The BFG KM3 is a great all rounder mud tire which offers a decent off road traction and a great on road experience. Off road the tire checks all boxes, while on roads, the tire has to compromise on some areas where the wet traction is the major one to look out for. Other than that, it's a great tire to have.
The Toyo Open Country MT is a confusing tire on wet as it does not provide enough lateral stability there as the tire severely lacks in overall siping and tread's flexibility. But on dry the tire is pretty great, in all departments, where you may have to compromise slightly while cornering (understeering issue), but only if you are going with E or F rated tries. Similarly off road the tire is okay, but nothing impressive. So overall it's okay for daily driving on dry roads, especially if you get smaller load rated tires.
