So, after how many restarts does the dreaded "Check spare tire pressure" warning go away? I received the warning yesterday and actually I deserved it as the full size spare was about 10 lbs low (Heavy duty Package) No idea why, no leaks found, so I simply aired it up to 2 PSI over the recommended 42 PSI and cranked it back in place. The vehicle has been restarted about 8-10 times since and the warning persists. Think it will go away or a dealer trip is called for? On all the other vehicles I've had, either you could check the actual PSI on each tire and the low warning would go away after air was added, OR they at least had a reset. Not so with LR.
