How accurate is our TPMS?

took new X5 x35d delivery with 19" rims: fronts were 41/43 and rears 50/52. adjusted to fronts 36 and rears to 44 per sticker. TPMS shows fronts 37 and rears 45. what pressure do you maintain fronts and rears? do you trust TPMS readings?

TPMS is not all that accurate - use a good quality guage
