So I when I purchased my winter rims and tires I chose not to install tire pressure sensors they would have cost me an extra $200, the guy at the tire shop said I would get a light on the dash showing a problem but that would be it no other issues. So I put my winter tires on back on Oct. 8 and no light on the dash came on until today Nov. 24. Anyone have any idea why it took my car over a month to realize it had no TPS sensors??
