Wheels and Tires

WARNING
Operating the vehicle with worn tires, improper tires or tires with improper or uneven tire pressure could cause loss of control or accident. Always use the correct size and type of tires specified for your vehicle. Always maintain proper tire pressure as recommended in the owner's manual and on safety labels. Always replace tires when tread depth has worn to the minimum requirement.
If you experience a wheel impact, such as hitting a curb, a large pothole or road debris, have your tires and rims inspected immediately. These types of impacts may cause hidden tire/rim damage that may not be noticeable during operation. This damage could cause tire or rim failures and result in accidents causing serious injury or death. If you are in doubt, have the wheel checked by your authorized Slingshot dealer or tire professional. Exercise care when parking along curbs and reduce speed if possible when approaching unavoidable potholes and/or road debris.

Tire Condition

Inspect the tire sidewalls, road contact surface and tread base. If inspection reveals cuts, punctures, cracks or other wear or damage, replace the tire before driving the vehicle. Refer to the SLINGSHOT Service Manual, or an authorized dealer can assist.

Tire Tread Depth

Measure the tread depth near the center of the tread on both tires.
  • Replace a front tire when tread depth wears to the minimum of 1.6 mm.
  • Replace the rear tire when tread depth wears to the minimum of 4 mm.

Tire Pressure

For an accurate reading, check tire pressure when tires are cold. Driving warms the tires and increases tire air pressure.
