TIRES
Operating your vehicle with worn tires will increase the possibility of skidding,
loss of control and an accident, which could result in serious injury or death.
Always replace tires when the tread depth measures 3 mm (1/8") or less.
Improper tire inflation or the use of non-standard size or type of tires may
adversely affect vehicle handling, which could result in vehicle damage or
personal injury. Always maintain proper tire pressure. Always use POLARIS-
approved size and type of tires for this vehicle when replacing tires.
