30mm wide wheels are gaining in popularity in the industry, as they add a significant amount of grip over conventional 110x24mm wheels due to their extra width and a larger contact patch. Root just launched their Lithium 120x30 wheels, which are a true 30mm width wheel, as opposed to their Lithium wheels, which have a 30mm PU but a 24mm core. If you are going to run the Lithium wheels and currently run conventional 110x24mm wheels, make sure that both your deck and forks are able to accomodate a wheel with a 30mm core.
Root Industries Lithium Wheels are 88A PU, which means that Root Industries intended them to be ridden on the street because they are harder and more durable than 86A wheels. Root Industries Scooter Wheels are 30mm wide at the core and should be used with 30mm wheels spacers. The PU width is 30mm. Most PRO SCOOTER FORKS and decks were designed to handle a 24mm wheel core. 30mm wheels are the new favorite of pro scooter riders due to their massive grip. While they are going to feel a little strange at first if you are used to riding 24mm wide wheels, you will soon learn to love the massive grip that they offer! But beware, since 30mm wheels are relatively new to market, make sure both your deck and forks can handle a 30mm wide wheel.Root Industries Lithium Wheels have a 120mm outer diameter, making them perfect for the intermediate to pro riders who are looking for maximum speed for big air park tricks. While 115mm and 125mm are only produced by a few scooter manufacturers, 120mm wheels are the norm now on any intermediate to pro freestyle scooter. Root Industries Lithium Wheels 120mm come standard with pre-installed bearings.
