Ok folks, need some quick advice. I will post a full summary of my trip in this thread when I return. But I wanted to ask about the stock Metzler tires. The area of Utah I am riding in has not had rain in a long time. The dirt ground is hard as concrete but is coated in layers of dust. It feels like I am riding on ice with these tires. To further complicate matters, the roads have a lot of gravel and rocks. If I ride in a stretch of road with any moisture at all , the tires grab great and I can really rip. Other wise, there's times when I am squirling all over the road.
I am in no position to trade out tires at this point in the trip and will prob buy K60's for future rides. I was thinking of airing down these stock tires to handle the off road stuff for this trip and need some recommended PSI numbers. I have access to an air compressor and can easily air them back up for the great highway trips in the area. I am currently riding at the manufacturer's recommended PSI but this obviously doesn't apply to what I am riding. I am mostly riding forest service roads but have taken a few ATV trails as well.
I really enjoy the harder ATV trails but don't want to damage the tires riding them at lower PSI. I can't see why this would harm them but wanted to check with the folks here. My return trip home is 440 miles of highway road in about a week.
