RC Car Tyres and Spur Gears are the under warranty ?

tyres once used need to be checked regularly, if they start to unglue then they need to be reglued back on. Its also possible that the tyre will baloon when run at a speed beyond what the tyre is capable. In both cases the tyres are not under warranty

This also goes for tyre use, once you start using them, its rare that warranty will cover them.

For Spure gears this is a similar story as spure gears are actually made to break , protecting the motor from damage. normally these gears if jammed will shear and just need to be replaced to carry on using the car
