I was just launching up on to a highway in Peabody, Mass. Off from Rt. 1 and onto I95 N. A great place to get up to speed fast. I get up around 85 mph or so ( a good commuting speed) and the TPS warning starts flashing and showing pressure. First was 25psi, then 16psi a couple seconds later, and then 8psi as I am rolling to a stop. Was ready to $#!+ my pants not knowing if it was the front tire or rear and trying to stop fast while switching four lanes.
I had 3 separate holes to plug up and 1 took 3 sticky ropes. A tattoo artist/Harley rider and his colorful girl friend stopped their VW Westfella to help me out. Great people! They had a bicycle pump that I was happy to kill myself with while pumping up the tire. And I was on my way home.
Had the tire changed out under my tire insurance plan for free.
Bottom line is that the TPS could have saved me from a rough landing (maybe not). A tire gauge in your pocket isn't going to help you out much.
