I wouldn't worry about 47 psi cold as being "overinflated" or dangerous. That said, I want to make sure that you realize that you can easily let small amounts of pressure out until it is back down to exactly where you want it, right? A $5 tire pen gage will get you everything you need once you've inflated a bit over your target.I can never get it exact when filling the tire pressure. Mine say 47psi. Anything wrong in terms of safety with running that high? Don’t know if overfilling by a small amount could be dangerous and if I should drop it lower.
