Hankook DynaPro AT-M. RF10's They come in two load index. Go for the heavier one. Stronger construction and slightly more tread depth.
Had mine for 35,000K and still 50% to the wear marks. Next set will be the same. Starting to drop off now on wet road performance (grip) but hey it's not a road or highway only tyre.
For a AT tyre there not to bad in mud at all. The only bad review I could find about them. is they are a little noisy once they wear down but mine seem alright and certainly way quieter than any muddy.
