- 30psi rear/27psi front: This is where I started out, and it was very good until I hit some deeper gravel where I felt the Horizon was dancing around, especially in the back, more than a wider tire should.
- 24psi rear/ 22psi front: Well, let’s test the crazy depths of air pressures, shall we? That was my thought going into this ride. However; the rear setting was just too low. It wasn’t that it felt draggy, or created high rolling resistance, but it was squirrely. It felt too low like a tire going flat. I ended up with 27psi in the rear for most of the ride. This totally eliminated the dancing around in loose gravel issues.
- 30.1psi rear/ 27.4psi front: Back to where I started. The Horizon tires have broken in by this time and the casing is working much better to absorb all the little gravel demons out there. So, this has become the go-to setting for now. Fast on pavement, ultra-smooth ride quality, and is still fast on gravel without drifting and skating around in the marbles.
