Temperatures have plummeted, we are seeing morning lows of -22*F ( -30*C ) and colder. Last week temps were around 30* F. ( -2*C ) Yeaah ...
I have also seen numerous flat tires around the city. Yesterday I saw 6 cars / SUV's with flat tires. WHY so many flat tires ? Is it the usual failure to check the tires for 6 months ( or ever ... ) and get caught out with a very low tire that now loses 5 or more psi just because of the temperature change ? Tire pressure will drop roughly 1 psi per 10*F temp drop. Or is there more to it. Do tires simply become so stiff in the cold that they sometimes lose their seal if they are under inflated by a large amount ?
I remember reading somewhere that people living in extreme cold climates sometimes run tubes in their tubeless tires, because below a certain temp, tubeless tires no longer seal reliably.
Thoughts ?
