Beware of the Load Range, as the LR-F tires have a significantly stiffer carcass than the LR-D version. Much better road grip and manners than the KO2's, including the tread life. Excellent dirt/gravel grip, average grip in the mud.

What drivers say about their 315/70 R17 tyres
The most recent owner reviews fitted in this size, in their own words.
The tires exceeded my expectations in every terrain! I posted multiple videos on my YouTube channel showing how they performed in all conditions and they are the only tire I will put on my Jeep and my Ram 2500 pickup.
Dry and wet are about the same, nothing terrible, but I have driven tires with better grip in both situations. The road feedback I knocked off some points just because of my particular setup. On a heavier larger vehicle I would expect it to be a point or two higher. Its pretty binary, you either dont feel the bumps and texture or you REALLY feel the bumps and texture. Handling also gets dinged harder due to the vehicle, you can feel the tires want to give up as they get pushed a bit at highway speeds. Again a heavier vehicle is likely to feel that less. The noise is about what you expect out of an AT tire, and as far as comfort goes, its better when I keep them at around 28-30 PSI on the road. By default the Jeep wants to see 37 PSI which is like driving on rocks. They do ok in the snow, but ice is pretty sketchy, especially on a short wheelbase vehicle.
Overall the tires have worn at less than expected rates (the advantage of a light small vehicle on these tires), and they are quite reasonable on road. They also handle the off road well enough for the trails we run (moderate difficulty in the rockies).
Overall, these are perhaps the best AT tires I have ever had. MT has done an amazing job getting these tires to have a smooth, quiet ride on the street, while also providing fantastic traction offroad. I have had them on dirt, rocks, and plenty of snow.
The tires are a bit on the heavier side due to having a more robust, 3 ply sidewall with sizable side biters. When aired down these really do help protect the sidewalls while also giving additional traction.
On the street, their noise level about average for an AT, despite them being more aggressive than most AT tires. This can be attributed to their asymmetric tread design. My Jeep has more wind noise than tire noise. They have full depth sipes which aid in wet traction, and aid them a lot in the snow. While they will not perform as well as a dedicated snow tire, they are 3-peak rated and have gone everywhere in the snow that I have asked them too. They have also had great tread wear. I live in the mountains, and our roads are known for chewing up tires faster than average. These have done well.
Offroad, these tires really shine. They have larger, deeper voids than most ATs. These really are more of a hybrid tire with an AT name. They will not due as well in deep mud as a dedicated mud tire, but they easily out perform AT's like the BFG KO2/KO3 in the mud. Their compound seems to work pretty well in the rocks. They are not as soft as some more purpose built rock tires, but they do well enough for most.
Its worth noting there is three versions of this tire. The P rated tires have much shallower tread, and the side biters are more of just a shallow design element and do not provide much protection/traction. There is the LT rated tires (eg: 35x12.50R17), which are designed for Jeeps/Broncos/etc and have a load range C or D depending on size. These have a softer compound, deeper tread, and deep side biters. Then there is the metric sized LT tires (eg: 315/70R17) which are load range E, and use a harder compound. These are intended for diesel pickups and such. Do not put these on a Jeep, you will hate them.

Where this data comes from
Owner ratings are submitted through the review form on this site, naming the tyre, the size and the distance covered, and are checked by hand before publication. Test results come from independent published tyre tests indexed by size, and label values from the EU EPREL database.
About the TR Score
The Tyre Reviews Score rates each tyre out of 10 using independent test results and the full body of owner reviews, so you can check a car-specific ranking against the wider evidence.
Who does the testing
Every test published as a Tyre Reviews test is run by Jonathan Benson, who has been testing tyres independently since 2007.
