iDrive tire pressure accuracy

HPIA4v2 · 04-04-2018, 03:10 PM

Wonder if the reading is accurate, I think my digital tire pres gauge says 37psi and the iDrive indicates close to 45psi

Perhaps your gauge is off. Verify with a manual pressure gauge.

Never mind, I think iDrive was still reading or I didn't drive long enough. This morning after driving about 30-min I checked again and it says 3 tires are 35psi and one 36psi.

Overall, I know that my iDrive pressure numbers are reported lower than actual by 1-2 psi. I guess that's not too bad.
