My roadster is stored for the winter and I started it today and backed it out into the driveway to idle and warm up to temp. I noticed the TPMS light was on and the rear right tire read 25 pounds. I topped off all tires to 30 but the light is staying on of course. I understand a few miles of driving is needed to complete the reset function but that will not be possible as Rosie is only covered by comprehensive during the winter months so driving it is out of the question right now.

My question, is 25 pound enough to trigger a light or after 8 years are my batteries finally starting to croak? I'm leaning toward the latter. I have read where 180 says we should get 10 years out of these but nothing is ever cast in stone.

Thanx guys!!
