Troubleshooting
Increased road noise or vibration

Reduced wet weather traction
Check remaining tread depth using a gauge; if the tread is below the legal limit, replace the tyres immediately.

Setup, Compatibility & Care
To ensure peak performance, the PS72 must be installed by a professional technician who can verify proper wheel balancing and alignment. Given the 225/40R18 specification, ensure your vehicle rims are compatible with this size. Regular care involves checking tyre pressure monthly, as specified by your vehicle manufacturer's placard, to maintain the even contact patch. Perform a visual inspection every 5,000 miles to look for debris or uneven wear patterns. Rotation is recommended every 6,000 to 8,000 miles, depending on the drive configuration of your vehicle, to promote uniform tread life across all four positions.
