Why motorist are advised not to o overrinflate their car tires or fill their gasoline tanks to the brim?

Motorists are advised not to overinflate their car tires because excessive pressure can lead to reduced traction, uneven tire wear, and an increased risk of tire blowouts. Similarly, filling gasoline tanks to the brim can cause fuel to spill, leading to evaporation and potential environmental hazards, as well as damaging the vehicle's emission control system. Additionally, fuel expands with temperature changes, and overfilling can lead to pressure buildup and leaks. Proper maintenance and adherence to guidelines help ensure safety and vehicle efficiency.
