TPMS Monitors

Not sure, maybe more part of the serious tire problem a few years back where shops were selling 6+ year old tires. I know thry have cracked down on the tpms issue multiple times to try and prevent tire relate accidents. Youd be surprised on how many people are driving on 6+ year old tires and tires that are worn in general, its scary. Thats why i replace my tires every 5-6 years regardless of what the tread looks like
