This procedure allows determination of optimal inflation for a vehicle’s tires based on observed wear patterns across the tread. The method involves applying chalk evenly across the tire’s width, driving the vehicle briefly, and observing how the chalk mark is removed. The pattern of chalk removal indicates whether the tire is over-inflated, under-inflated, or properly inflated for the vehicle’s weight and typical operating conditions.
Correct tire inflation offers several advantages, including maximized tire lifespan, improved fuel efficiency, and optimized vehicle handling and braking performance. Historically, tire inflation recommendations were based solely on vehicle manufacturer specifications, which may not account for modifications like aftermarket wheels, heavier loads, or different driving styles. This simple, practical test provides a more customized and accurate approach to tire pressure management.
