As part of a pre-alignment inspection, the technician should first check

• A. Wheel Alignment
• B. Tire Pressure
• C. Brake Fluid Level
• D. Steering Angles

Answer: (B)

Verifying tire pressures before performing an alignment is essential because tire inflation directly affects how the suspension sits and how the wheel contacts the road. If tires are under- or over-inflated, the ride height and the contact patch change, which shifts camber, toe, and caster readings and can lead to incorrect alignment targets. Alignment equipment assumes tires are at the specified cold pressures, so correcting pressure first removes a variable and reveals the true geometry that needs adjustment. The other steps—checking the wheel alignment or steering angles first or brake fluid level—don’t provide a reliable baseline because they rely on proper tire setup or are unrelated to the alignment measurements.
