I briefly considered Duratracs as well.
Here are a few things to consider when purchasing.
1. You’ll look like a MOPAR product.
2. Beyond light off-road, they have been known to shred. The weight savings comes at the expense of sidewall toughness.
3. They also have been known to chunk.
4. They get louder and louder with age.
5. Did I mention you’ll look like a MOPAR product?
Rotational inertia is real. With a tune you won’t notice the different behind the wheel, however.
Duratracs I believe are a great tire but are lighter duty. If you aren’t going off road much and aren’t doing a lot of more serious off road... I don’t think you can go wrong with them, the generals or the Ko2s.
