- The problem
- The existing certification labels contain incorrect rim size information. This is a non-compliance to federal motor vehicle safety standard no. 120, "Tire selection and rims for vehicles other than passenger cars". The existing labels specify the use of 16.5X6.00 Rear wheels instead of the correct 16.5X6.75 Wheels.
- The fix
- A new label will be installed indicating the correct size rear wheel. This will be performed free of charge.
