Talking about the monsoon season and sudden rains, one of the most import things that’s gonna save you from rear ending someone in front of you are your car tyres and tyre grip during this season.
If you face light showers every now and then, your normal off the shelf tires will do just fine. You just need to be extra cautious about the speed of your vehicle and braking distance. But in case you are living in a area that sees a lot of rain and you have to drive through standing water most of the times, there are tires specifically designed for your needs. They are usually called wet weather tires, rain tires or simply wet tires. 
Circumferential Grooves
Wet tires are cut or molded with patterned grooves or tread in them. These are the tread lines that wrap long ways around the tire. In deep water and at high speeds, a tire’s ability to stay in contact with the road depends more on the tread pattern: the lateral and longitudinal grooves. The purpose of these groove are to disperse water from underneath the contact patch as quickly as possible. As tires spin on wet surfaces, circumferential grooves channel water away to maintain good traction. The patterns are designed to displace water as quickly as possible to the edges of the tyre or into specially cut channels in the center of the tire.
Compound of Rubber
Tire manufacturers mix and match several compounds of rubber to best suit the need of the customers. So if a tire maker is specifically making a tire for the wet driving conditions, it would use a softer compound for the better grip when driving through water (standing of rain).
Contact Area
Contact area or contact patch is area when tire and the surface of the road/track/ground come in contact. Wet tires usually have narrow contact area with the road. The reason is to lessen the contact patch, hence reducing the risk of car hydroplaning aka aquaplaning; wider the tire, harder for the grooves to disperse water. Sometime wet tires are also made smaller in diameter, making the tire rotate far quickly than usual and dispersing water. This is a usual practice in many forms of motorsports.
The question is, if you truly need wet tires or not because some areas of Pakistan see a lot of rainfall. If you have to travel a lot on motorways, it is always better to invest in your and your passengers’ safety.
