Left and right tire pressure difference
Hi all,
I noticed just one week after getting my Service A that my tire pressure is different for my left to right, even when I'm driving straight on the freeway.
The difference is usually 1 psi for the front (left is lower than right), and 0-1 psi for the back (left is lower than right)
Is this normal?
Need to confirm before I bring it back to the dealership. (Forgive me if this seems like a noob question)

Always adjust pressures on "cold" tires. That means that you haven't driven on them yet. After that, you can't make a judgement on pressures on "hot" tires. A psi or two one way or another is nothing to get worked up about.

i would imagine that the sensors are probably only accurate to 1 or 2 psi - so most likely they are pretty close

If your worried about the difference in pressure from side to side, set your pressure when both sides of the vehicle are in the shade.
Frankly, one psi is, in my view, inconsequential.
Was surprised and pleased to find the tpms sensors and my pmel calibrated tire gauge indicated identical pressure.

As we know, black tires absorb heat when exposed to direct sunlight causing increases in pressure. It's not uncommon for parked tires exposed to direct sunlight to have inflation pressures as much as 4 psi higher than the tires sitting in the shade.
