I've been thinking for some time a TPM system sounds like a good idea, especially one with heat sensing. I wondered which system, the inside wheel or valve stem cap was better, and what brands have been the easiest to setup and use and is most dependable. I tried a thread search but couldn't find anything but I may not have done it right either. Anyway thanks for the ideas.

Ok. From what I've heard on this subject is the valve stem type are common to be stolen in parking lots. Only takes a few seconds for a punk kid to steal all you pressure caps.
