Sure am glad the state of SC USA doesn't nannymonger drivers who actually look at their tires often (and check the air in them on a regular basis). I bet those regulations (in at least one province in Canada) are inflexible if you chose to install aftermarket TPMS instead of paying BIG $ to fix a shoddy outdated system that came with the car. Bypassed mine, took the sensors out (anyone want to buy them?). If and when I need air, I put it in. Too much (during radical changes in weather), I let some out. If I trend adding air (slow leak), I find said leak and fix it. Blowout, no working TPMS in the world will help.
