One place I hope to tour is in New Zealand. My wife and I have friends that recently moved there and I've begun researching/planning a tour there.
One issue that presented itself immediately was tire width. It seems that riding on gravel covered dirt roads is where some of the best riding is on the South Island. Looking at a few photos shows people biking on them with very wide tires.
The widest tire I can get on my Waterford 1900 is 700x38 tires with fenders but given the trouble I've had with fenders, let's assume 35mm.
For those who live or have ridden in New Zealand, would 700x35 tires be wide enough to handle the dirt roads in New Zealand?
