Being a new front range rider and all that,and I'm about to splurge on new shoes for my 2011 KLR. I live up Sugarloaf road in Boulder, so I get to hit the twisties no matter where I ride.Also lots of trails. I'm looking for a 50/50 tire or combo; I.e. k60 rear/ TKC 80 front. I think Ive settled on a set of K60s, with a 140/80-17 rear due to the fact that a lot of people say the 130 size wears faster. Being new, I get a little overwhelmed by all the info, and believe me I have researched the shit out of tires. What I'm looking for is confirmation, maybe, that these tires will be good for riding all the variety of Front range riding I'll be learning on. Think CO. riding only and No0b... I plan to ride the crap out of these then put on a new set before my big trip out west in Aug. So these will be my training tires so to speak. Local suppliers? Should I buy them online and spoon them on myself so I can get some practice, or have a shop do it? which shop? Anyone want to help if I buy them online?
