There are some tell-tale signs that it is time to replace your tire would be if you notice the following:
1. White threading wearing through the walls/rims of the tire. See photo below in #2
2. Tire slime/sealant is escaping from the inside of the tire (tire slime in stock Onewheel boards is blue and gooey but can take on different colors). See photo below:
3. The tire constantly needs to be inflated to maintain PSI. Air loss is normal over time, but you shouldn't have to inflate daily
4. Tire tread is flush/level with circular wear indicators (Slick tires only). In the picture below, the tread has not worn down to the indicator level and is in good condition:
We offer two options for tire changes:
1. You can purchase tires and tire accessories on our website here. We will ship you the tire and you can perform the tire change yourself. If you go this route, we also recommend purchasing tire sealant, tire valve replacements, axle bolts, and tire spoons/bead breaker (if you are not familiar with changing tires). This can be a bit tricky and will require some knowledge on how to change tires, but you are more than welcome to try it if you feel comfortable.
2. You can purchase a tire change service here, we will provide the label, you ship the board to us, we change the tire and evaluate the board and ship it back to you. We are the only authorized service department to perform a tire change. Please be aware that this is only for customers living in the 48 Continental States.
