I've been reading some posts on tires lately and I see everyone throwing around references to 50/50 and 80/20 on road/off road, then reading further between the lines I'm seeing that they are calling gravel roads off road. Is this what is considered off road, a gravel or dirt road? I guess I come from a different background, off road to me is tight single track not the road to someone's house that I would drive my wife's Juke down. Am I wrong in my thinking? Or are there a bunch of posers out there that talk tough?
