I'm sorry if this has been asked a million times but I couldn't find it in a quick search and I plan to get my new winters installed on Monday.

The tire pressure monitor light is a really simple system, as you know, that simply compares RPM's left to right and decides a tire is low if it consistently revolves more.

The question is, if you do not put the sensors on your winters does the light stay on all the time or can you defeat the feature entirely? Or better yet, where can I get a generic sensor valve for low $ and then I will just install them?

TIA
