Tech & Installation

Two different ways a wheel finds its center on the vehicle — and why getting it wrong shows up as vibration, not a crash, until it does real damage.

If your wheel's center bore is larger than your hub, a ring closes the gap and keeps the wheel centered. If it's smaller, no ring can fix that.

TPMS is the system behind that tire-pressure warning light. Here's how it works, why wheel and tire changes trigger it, and how relearns actually happen.
