I was just curious to how tyres work in the rain. How does the tread shift the standing water so the tyre can have traction? Any information would be appreciated.

"...Regularly spaced grooves are avoided because they set up harmonics which can cause hefty vibrations..."
which explains one of the most curious aspects of tire treads - the complexity of the geometrical shapes.

Balancing and performance I would also imagine. I would tend to think that the blade profiles would not be the same.

Tyres are designed with specific tread patterns and rubber compounds that allow them to maintain grip on wet roads. The tread patterns are designed to channel water away from the surface of the tyre, allowing it to maintain contact with the road. The rubber compounds are also designed to be softer and stickier, providing better traction on wet surfaces.
Tyres can lose traction in the rain due to a combination of factors. One factor is the buildup of water on the road, which can create a layer between the tyre and the road surface, making it more difficult for the tyre to maintain grip. Another factor is the speed at which the vehicle is traveling - the faster the vehicle is moving, the less time the tyres have to displace water and maintain contact with the road.
Tyre treads play a crucial role in maintaining grip on wet roads. Treads with deeper grooves and more sipes (small slits in the tread) are better at channeling water away from the surface of the tyre, allowing it to maintain contact with the road. Treads with a more open pattern also help to disperse water more efficiently, reducing the risk of hydroplaning.
Yes, tyre pressure can affect performance in the rain. If the tyres are overinflated, there is less surface area in contact with the road, making it more difficult for the tyre to displace water and maintain grip. On the other hand, if the tyres are underinflated, there is too much surface area in contact with the road, resulting in a higher risk of hydroplaning.
Yes, there are tyres specifically designed for driving in the rain. These tyres are often referred to as "wet weather" or "rain" tyres and have treads with deep grooves and more sipes to improve water dispersion. They also have a unique rubber compound that provides better traction on wet surfaces. However, it is important to note that even with these special tyres, it is still important to drive cautiously and adjust your speed to the road conditions.
