Tire Pressure Suggestions

So, I had a very hard pair of rides on my XRC and since I am new I really thought I had somehow gone backwards in skill.

However, it is cold here and I had left the thing in the trunk… I had a tire at 11.5psi. I don’t know much, but I know that is the wrong answer.

I don’t really know what the right answer is though. I am primarily riding on asphalt and concrete at the moment with occasional patches of nerve wracking gravel.
