The tire is the vehicle's contact with the road. Pressure warnings, vibration, pull, noise, and wear patterns must be interpreted with the vehicle placard, tire condition, wheel mounting, and chassis condition.
System guideSuspension supports the vehicle while allowing controlled wheel movement. A clunk, pull, poor ride, or unusual wear pattern can also involve tires, steering, brakes, mounting, alignment, or body structure.
System guideThe steering system changes wheel direction and returns road forces to the driver. Pull, vibration, looseness, and heavy steering should be separated from tire, brake, suspension, alignment, and road-surface effects.
System guideRepeated pressure loss points to the tire, valve, bead seal, wheel, or changing conditions—not automatically a TPMS fault.
beginnerUse speed, braking, acceleration, road surface, and steering input to separate wheel/tire, brake, hub, axle, suspension, and steering causes.
intermediateUse road speed, steering load, acceleration/coast, gear or drive mode, and tire condition to separate wheel-bearing, tire, CV/shaft, differential, axle, and other rotating-noise paths.
intermediateAI guidance is separate from verified IAR sources.
