rills
Splines are parallel grooves on the side of a shaft that engage with matching grooves in a socket. They allow power to be transmitted between two rotating elements. Splines are used on axles to allow them to be removed and replaced.

To change an actual tire you need a tire machine to get it off the rim and the new one on. -If you mean the change the WHEEL and tire on a car, then you just need a jack and a tire wrench.

No the grooves are the tread, the profile is the height of the tire from the rim measured in percentage of tire width.
Tire grooves channel and disperse the water on wet roads. If it weren't for grooves, your tires would be 'aquaplaning' on every patch of water, and not gripping the surface.
When tires are made, the tread pattern has grooves in them. There are parts of the grooves that are not as deep as others. When the tire has worn down to that level, the tread has worn away to the point where they are no longer safe to drive on. The bars are clearly visible going across the tire.
The "tread" is the part of the tire that is supposed to touch the ground. A tire with no tread would be a tire that is not supposed to touch the ground. You may be wondering why tires have a pattern of grooves (a.k.a., voids) in the tread. They're for bad weather. The grooves allow rain, and (if they're wider) mud and snow to squelch out from under the tire so that the tread can come into contact with something solid on which to get a grip.
The grooves or "tining" placed on concrete bridge decks (surfaces) are created for for automobile tire traction when it rains and to help direct the water runoff. Typically the grooves are created in the transverse direction across the direction of automobile travel. More recently longitudinal grooves have gained favor because there is less noise generated when tires follow longitudinal grooves when compared to more noise generated when tires cross transverse grooves.
Mostly, they are to channel water away from the underside of the tire. They also improve the tire's grip in turning, and in moderately snowy conditions. The largest selling type of tires are what are called "all season radials" - good for any kind of weather.
This is called the tread. It must be durable and heat resistant, and its grooves help keep it in contact with the road, especially when it is raining.

I assume you mean GROOVES - the Glacial Grooves were formed by the receeding glaciers.

A quarter has 119 grooves, or reeds. The grooves are used as an anti-counterfeiting strategy.
