Thanks for all the advice.
I am using presta valves. When I say check valve I am referring to the inner works of the valve that allows air in and not out. Maybe that is not the proper term for bikes. Sorry.
I ran some trails tonight, but they were hilly/sandy trails. I ran the bike at 30 psi. It sure felt weird, and would be pretty slow on the pave. I do like to ride fast on the highway.
