The wheels of your skateboard can greatly affect your ride in numerous ways, such as the speed, your ability to take control of the skateboard’s movements, and what you feel while riding the board. The good news is that they come in various sizes, levels of durability, and colors, allowing you to pick one that suits your skateboard preference and style.
Ollie 180: an Ollie where the skateboarder and the skateboard spins 180 degrees after leaving the ground. Both the skateboarder and the skateboard rotate in the same direction (Frontside or Backside) with the skateboarder's feet sticking to the skateboard. This trick is usually referred to as a frontside or backside 180, or less frequently and more popular with older skateboarders and/or when performed on a bank/quarterpipe, a frontside / backside ollie
The longboard, a common variant of the skateboard, is used for higher speed and rough surface boarding, and they are much more expensive. "Old school" boards (those made in the 1970s–80s or modern boards that mimic their shape) are generally wider and often have only one kicktail. Variants of the 1970s often have little or no concavity, whereas 1980s models have deeper concavities and steeper kicktails.
To get higher ollies, I would suggesting resting your back foot on the very end of the tail and the front foot in the middle of the deck to allow for more slide. Popping as hard as you can and catching your board in the groove of the nose with you ankle practically resting in the groove will level the board out in the air. after this initial movement slide you feet back to the bolts on the tail and nose to ensure a clean landing.
