Does The Design Pattern On Tires Contribute To The Road Grip?
The article talks about the importance of the thread pattern on tires. The design pattern seems to help when the tire is subjected to wet road conditions. Greater the number of threads; the greater is the amount of water it can hold and displace quickly. The tire size size 195/65 R 15 can displace about 15 liters of water per second!
Then there's something called Groove Ratio: Higher the ratio of grooves to rubber; higher is tire's capacity to displace water.
I'm still a bit uncertain about how the tire grooves ensure more grip on regular, dry road conditions. Anyone?
