2015 Kia K900: Service Includes Wrong, Random Tire Pressure
June 9, 2015
Recently our dear leader finally figured out the right tire pressures for our 2015 Kia K900. Although the car calls for 31 psi all around, he determined through some tinkering that 33 psi front/35 psi rear felt better. Then we took it to the dealer for service.
The tire pressure they chose was surprising (unless you looked at the photo above, in which case it won't be surprising at all).
39 psi in our garage. 41 psi in the garage where I park at home (ignore that 38 psi number; I started bleeding that tire before my brain said "Dude, take a photo!") This for a car that calls for 31 psi all around on its door-jamb sticker.
I double-checked the work order to make sure that checking/adjusting tire pressure was included in the free service and indeed it was. The paperwork says they set it to 33 psi, however. That isn't what the door sticker calls for, nor what we'd set it to ourselves. It also wasn't 39 psi which is, as far as we can tell, completely random.
Five minutes of crouching with a tire pressure gauge equipped with a bleeder valve fixed everything.
