I'm posting here with this Q hoping there are some guys who have experienced the same road (or type) with the same predicament. My rear TKC80 has about 40% tread left on the centre. I'm about to head out of Alice for Perth via the Great Central Rd and have about 1000kms dirt and 1000kms sealed (roughly). Do I put a new conti on or will the Great Central allow me through (just)? From Perth I put my tourances back on and carry a new set of Conti's to Broome to ride over to Cairns - hence why I don't want to half use up a conti rear before Perth. (My vocational guidance counsellor didn't recommend I make a career in Logistics.) I'm ready to go with the tread I have left but need to know if I am asking too much. Cheers, Wolfy.
