Does anyone happen to know the torque specs for the valve stems that come with Kosei K1's? I bought a set, but the valve stems arent installed since I bought just wheels, not wheels and tires (Tire Rack). I dont know if they have a specific torque spec, or if you just tighten them snug, or if there is a universal spec. I would leave it up to whoever mounts the tires on the wheels, but since these are competition tires, most shops ive dealt with are a bit weary or even mounting the tires. Not only that, I want it to be right. If anyone can help, it would be greatly appreciated.
