I bought a set of bullet rims, not really interested if anybody likes them or not , I know there is a big debate on them....so...... my question is there are blue sensors with a band clamp attached to them around the rims, the idiot I bought these also took 1 of them off and said they were for speed.... I have a feeling they were for the tire pressure system..... anyways do I need them on here since these are not factory rims, or can I remove the rest of them or do I need to buy 1 to replace what he took off. Thanks
