Long story short, I'm visiting my sister in CT and someone stole my OEM aluminum valve stem caps on my IS350.

Are there any risks in not using any caps for a couple of day or replacing them with rubber/plastic ones? Does the TPMS utilize the aluminum cap - Googling is vague?

Thanks for any help.

 

i don't think it's going to matter. i think technically even without the caps it's still ok.
