I have a heavy road bike with off road tires, as where I live all roads are a challenge. On my way to work I have to navigate around potholes and cracks in the road, partially asphalted roads, gravel, grass, tree roots, and so on. It always gets extra interesting when I return home with a basket full of shopping. I feel really good with the bigger tires, as they feel steadier and obviously more solid. They increase my feeling of balance and safety on the road.
