Your tires' contact patch ensures your vehicle's traction on the road. The contact patch and traction level depend on, among other things, the tires' pressure.
Because the tires constitute your vehicle's only point of contact with the roadway, it is essential that you give them particular attention to ensure proper traction.
Traction on the road depends on tire quality, wear and air pressure.
The portion of the tread that actually makes contact with the road surface is roughly the size of the palm of your hand. This is all that keeps a ton-and-a-half vehicle on the road.
This is why you should check your tire pressure every month to make sure it complies with the manufacturer's recommendations.
About tires…
Tires that are inflated with nitrogen are less sensitive to changes in temperature, but they can still spring a leak or go flat.
Remember to check the pressure in the spare tire and pressure differences between tires, since this could vary.
Some vehicles are equipped with a tire pressure monitoring system (TPMS). The device's warning light is located on the dashboard and switches on when a tire is underinflated.

I want to go deeper and not just provide basic answers but give people all the information they need. It feels great to get off the phone with someone who seems satisfied.
