I'm currently in the process of looking into new rims for my 8. I have the ones picked out but i have a few questions about the tire pressure sensors. Is it a good idea to keep them also if i don't is my dash light going to stay on since they can't pick up the sensors. A buddy of mine is interested in buying the rims and tires for his Mazda 3 and the sensors won't work in his car anyway. thanks

 

You should keep them. That's like throwing away 400 bucks. Have them installed in your new rims (if they accept them). And yes the light will blink if you don't have them installed.
