SERVICE BULLETIN

NUMBER: 254120032.01
MODEL: Karma
DATE: April 11, 2012
MODEL YEAR: 2012
TITLE: Goodyear Tire Wear
PRIORITY:
Vehicles in Operation
APPLICABILITY:
2012 Karma fitted with standard Goodyear tires
MARKET REGION:
U.S., Canada, and Europe
PURPOSE:
Under typical operating conditions, the shoulder rib may appear to be wearing at an accelerated rate.
Depending on driving style, this may apply more to the front tires than the rear tires.
Normal Tire Wear
There is a uniform thickness of usable rubber across the entire width of the tire. Tread depth at the shoulder “rib” is reduced compared to the center of the tire. This helps the Karma achieve excellent steering and
dry road handling performance. Shoulder ribs will still have usable tread rubber, even though they
appear worn. The standard Goodyear tires fitted to the Karma have wear indicator bars that determine
when they have worn to their acceptable limit.
CAUTION!
Goodyear tires fitted to the Karma are classified as a ‘summer tire’ and use a softer rubber
compound for driving conditions above 50 degrees Fahrenheit. Hard cornering and large
steering angle maneuvers will accelerate shoulder wear.
Assessing Tire Wear
Locate wear indicator bars between adjacent tread ribs, they will align with one of the nine (9) triangle indicators near the upper sidewall of the tire (See Image). Inspect wear indicator bars closely, once they
become flush with the road contact surface of the tire, replace tires immediately. Your Fisker Retailer will
evaluate tire wear during regular service visits.
