What is the difference between a flow through and a non flow through tire pressure monitoring system (besides price)? Is one system better than the other? Lakeside
I have the flow through. The air flow is somewhat slow, but if I am only topping a tire off, it is OK. If I had an almost flat tire, I would just remove it while adding air, then re-install it. That is what you would have to do anyway if you had the non-flow through.
