What's the difference? Is the 29er TLR just an updated version of the Mud X and if so what's been updated?
TLR will be tubeless ready, so should mean (in theory) thicker sidewall and tighter bead. In my experience of Bonty tyres, their sidewalls do wear surprisingly quickly (well, it surprises me), so it could be a worthwhile investment. But this is not from handson experience with the Mud X TLR.
TLR=Tubeless Ready.
TLR = still works on a normal wheel but is a bit more of a faff to fit.
they're about the best 29er mud based rubber you can get.
Beavers are better
Mud X 29rs were tubeless ready but they have been superceded by the TLR Mud 29er which seems to be the same tyre but with thinner sidewalls , they also make a point of mentioning that the knobbles are cuttable to customise your ride but to be honest I assume that to be the case on all tyres unless somebody has invented rubber that you can't cut with a knife and made tyres from it .
