I Have the 18" setup on a 4matic, and am wondering about the 38psi all around. Anybody adhere to that or keep the standard 32 all around?

I have it @ 40 PSI all around, NYC pothole everywhere!

The TPMS light goes off at anything less than 30. I keep mine at 36.
No issued TPMS wise, I have it reset for 32. Just not a fan of such a high PSI in a passenger car. However, I guess I should go w/ the recommended setting. Must be there for a reason!
