Rain Groove

Another important engraving on tire tread is rain groove, which are gaps on the surface designed in a manner as to channel out water once it comes into contact with a tire. The rain groove was introduced in the late 20th century, greatly enhancing tread groove patterns they vary region wise such as in tropical of Philippines and South America, special emphasis is put on this particular feature. Heavy rainfall is the main reason for special need for these regions. But generally it’s a part of every tire to channel water from a tire’s footprint.

Some tire has special tread patterns which do not necessitate the presence of grooves since their very design pumps water out while flexing. This creates smoother ride compared to tires which have plethora of groves on their tread. Grooves help a vehicle maintain stability in skidding roads when they are wet and allow better traction. The groove mostly starts from the centre of tire ending all the way till the tire shoulder. They are mostly in curved shape to channel the water better without creating much splash.
