Just get 4 new TPMS and have them installed in the snow tires and enjoy life.
Life expectancy is about 8 years on these Li-Ion batteries and once they are shot the TPMS is shot.
Based on my calculations and the expected "normal curve" of TPMS battery failures by time in service, I'm projecting that 8 years will be the "mean" time of failure. We'll see more battery failures going in to will be the dominant "fest" discussion issue going forward for the next five years! It will make the HPFP issue look like a mere "bump on the road" (as Obama says).

Big opportunities for indy shop owner's...and I expect that some will retire to Jupiter Island in Florida when this is all over...does Tiger own a BMW?
