TPMS Question

[djmark]

I'm sure this has been covered so sorry if so. I have an 07 Tahoe. I just put 20's on it and the service TPMS light is coming on. When I hit the check button it says LF 32 RF _ LR 32 RR32

Thanks,
Mark

reprogram your tire sensor. If that don't work you might have a bad sensor.
