Lots. Really good. Great. Really Good. Really Great.
Ok without being an a$$, as I've stated probably in this post it is a great performing all round tire. I'm really happy with the performance on snow and ice.
I only have TSL's and Cooper MT's to compare them to, but I'd say they perform at least as well as the TSL's in the mud. That doesn't include when you are using the TSL's side tread to inch your way along ruts the TSL's are great for that. But on a slippery, rocky, mossy trail, I'd prefer the Trxus. Snow and ice, the Trxus. Road, the Trxus. Wear...well the Coopers wore really, really well, but then again the tread compound was like steel! For a real performing trail tire the Trxus wears exceptionally well.
