The calibrated inflation level within the tires of a Toyota Highlander, measured in pounds per square inch (PSI), directly affects vehicle performance, safety, and fuel efficiency. Adherence to the manufacturer’s recommended specifications is crucial for optimal operation. These specifications are typically found on a sticker located on the driver’s side doorjamb or in the owner’s manual.
Maintaining the correct inflation level optimizes tire lifespan by ensuring even tread wear and reduces the risk of tire failure. Proper inflation contributes significantly to fuel economy, as under-inflated tires increase rolling resistance, requiring the engine to work harder. Furthermore, properly inflated tires enhance handling and braking performance, contributing to overall vehicle safety, particularly in adverse weather conditions.
