The tire of the car should be properly maintained and taken care, most importantly the tire should have proper air pressure. This is possible only by using a tire gauge to measure the amount of air present in the car for swift driving. The tire should be properly inflated neither over not under-inflated other it can create risk factors. So, the tire must be checked at regular intervals with the help of a tire gauge. The tire gauge also has a keyring attached to it to fix the keys of a car or other place.
