Aftermarket Tire Pressure Monitoring systems
 

Has anyone tried any, which, and what are your thoughts. I searched and found a couple of threads, but few posts and not much info.

I can tell if mine get low. I check mine and the missus occasionally. But the wife and daughter are unlikely to know, and even if you check weekly, you could have a problem in a day or even hours. I just changed a tire for my daughter on the side of the freeway that I suspect was the result of a slow leak.

I think it would be nice to add a TPMS to both the wife and daughter's cars, but I'd like to hear of some experience if possible.

It looks like the systems from TireRack are about $200

Hmm, the last time I saw aftermarket units, they strapped to the inside of the wheel. It seems like most are now attached to the bottom of the valve stem. That's unfortunate. The wheels on my wife's car (came with the car) have 2 valve stems per wheel and the stems are red anodized Al. Having to replace one of the stems would suck. I don't see any more of the things that attach with a strap. Bummer.

How about something simple and cheap like this?

It would rely on someone to look at them daily. I could maybe get the wife to, but doubtful on the daughter.
