I have run TrXus MTs from 2003 - 2013 (with BFG AT/KOs and BFG MT/KMs for a combined 4 months, in between). They work okay in muddy situations - they really aren't a dedicated mud tire like the TSL-SX. For rocky trails, pavement, dirt, and light mud, they do great. Of those 10 years, I only had 1 trail puncture from a sharp stick on a beach down in Mexico.
2004 - On moderate rocky trails, they perform well without blowouts or punctures.
2005 - They work great on the sand when aired down to about 14 psi.
2005 - I briefly ran BFGs back to back, but then went back to the TrXus MT after receiving a trail puncture.
2012 - They survive rocky trails like 'Gold Mountain' without much worry.
2013 - I sold my last TrXus MT after buying BFG AT/KOs for $500 This spare went for $25 with only 2/32nds of tread.
