After searching the reviews on the forums and manufacturers' websites, I still feel like I'm just guessing. I'm not comfortable walking into the local dealer and letting them "sell" me on a particular tire for fear that they'd just be pushing whatever they have in stock or need to unload. That fear may be unfounded, but I haven't yet built a relationship with a local dealer that I can trust. My bike is a 2002 1150GS. I bought it at the beginning of last season and rode roughly 6000 mostly paved miles on the Michelin Anakees that it came with. Living in Massachusetts, most of my riding is on pavement, but I am now actively seeking opportunities to get in the dirt. This years plans include a trip to Skyline Drive and the Blue Ridge Parkway, the Trans-Mass Trail and Puppy Dog Route through Vermont, a trip to Hamburg for the International Rally (if I can get away), and possibly an attempt at an IBA Saddle Sore. The remainder of my miles will come from commuting, long day rides on pavement, and exploring all the unpaved roads that I can find. Is a 90/10 on/off-road tire the right choice or do I need something more aggressive to get through the TMT/PDR ride? I will try to time this ride so that mud conditions are minimal. I'm guessing that something more aggressive would be unsuitable for the bulk of my mileage which is paved. I've read that the Heidenaus are a poor choice for wet pavement conditions which is a concern, because I don't want my paved road riding to be limited by weather conditions. I really don't have a whole lot of basis for comparison so I wouldn't expect to notice the subtle differences that a more experienced rider would pick up on. My goal is basically to not buy a completely inappropriate set of tires that would be dangerous or prevent me from completing the rides that I have planned. Any input would be greatly appreciated.
