If there is a directional arrow on the side wall of the tire, then that should be followed.

The tread of a tire or track refers to the rubber on its circumference that makes contact with the road. As tires are used , the tread is worn off , limiting its effectiveness in providing traction. A worn tire tread can often be retreaded. The word tread is often used incorrectly to refer to the pattern of grooves cut into the rubber . Those grooves are correctly called the tread pattern, or simply the pattern .
The pattern of the rubber part that meets the road.
It really does not matter how many there are as there are several around the tire. When the tread wear indicators appear flush with the tread you have 1/16" tread left and should look to replace the tires very soon.
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 what you step on, the riser is the part going up. Rise=riserThe tread is what you step on. The riser is the upright piece your toe hits.
This tyre pattern contains both asymmetric and directional features.

A tread climber burns more but it really depends on the workout that you do. You can burn just as many calories on a treadmill as a tread climber but your going to have to work harder. If you run say, a 10 minute mile on both, the tread climber will burn more.
Hydroplaning occurs when the tires' tread is unable to expel enough water to maintain a rubber contact patch on the road. The function of tread is to allow the "high" part of the tread pattern to cut through by forcing water (and other road grit) into channels and grooves surrounding the tread blocks. When the water gets too deep for the tread grooves to cut through it and force it between the tread blocks, the "high part" of the tread blocks lose contact with the pavement and looses traction by hydroplaning.
