Durometer - Hard vs Soft Skateboard Wheels

[VIDEO] What this guy is saying isn't entirely correct. I recommend you watch this video about the durometer scale. (I do think 79b ends up being pretty hard though like 95a?ish)

long version [VIDEO] and short [VIDEO] Very short : 100A means they are as hard as possible, will make a lot of noise, will slide more easly (for grinds and every trick where the wheels touches the ground) and will be terrible on rough roads or paved. Best for skateparks. 90A is the middle ground, you can do almost any tricks with them but they're already way more comfortable (and you're not doing so much noise eithe

[VIDEO] honestly, this video will do better than I can at explaining it. The higher the number, the harder the wheel. The letter represents the scale or like range the tool measures, so softer wheels are usually b, and harder wheels are a. Technically, all wheels have both an 'a' and a 'b' value, and actually hard wheels are measured with a 'b' scale and then the value is converted to the 'a' scale to portray a highe
