Since we're on the topic of the TPM sensors...what are their live span? Don't they have a battery to send a signal? I have a 2006, 140,000 miles and due for my 3rd new shoes. The low tire alarm really annoys me in cold weather. I glance at my tires every day and can till if they are low. In addition have ScanGuage (which you should all have) and can till instantly if I have a decrease in performance/mpg that I have a problem. But if I have them removed wont I always get a low tire pressure? Likewise, always annoying when I air down for off roading. Probably cant bypass the computer. OK, have not searched for "bypass low tire pressure alarm". Bet its on this forum.
