Warranty on wheels?
Unfortunately, no wheels can withstand everything. Wheels that are produced for the purpose of making tricks, are often exposed to extreme pressure and have therefore, like all other wheels, limited durability.
Every time you practice spinning tricks like a tail whip or a 360, you land sideways, which is hard on the wheels. If this is repeated many times, the material of the wheel can break or parts of it can be torn off.
So how do you decide, whether it can go as a claim case or if it is broken due to usage?
Here you see a picture of a new wheel (right wheel) and a wheel, which is reasonable new, showing less than 30% wear (left wheel).
If the wheel looks reasonably new with less than 30% wear (as described before), and the urethane has clearly separated from the hub, then there might be a production error (see picture).
If the wheel shows more than 40% wear and the urethane is torn off or broken, but still attached to the hub, then this shows that there isn't a production error (see picture).
If you brake very hard on the scooter, then the rear wheel can be blocked, creating so-called "flat spots". A flat spot gives a straight line in the bend of the wheel and makes the ride bumpy. A "flat spot" is not a production error or judged as a claim. The reason for a "flat spot" is (wrong) usage of the scooter.
