This Internal Audit Charter establishes the framework of the OICâs Internal Audit Function (IA Function) so as to ensure that internal audit provides the Commissioner with added assurance and advice, independent from line management, on risk management, control and governance processes.
Replacing Tires by Mileage. The average tire can handle about 40,000 miles of travel before it starts becoming unsafe. That number depends on the vehicleâs weight, weather conditions, the types of surfaces you drive on, and how many nails you run over. In other words, donât take this number as a certainty. If your tires are reaching 40,000 miles, though, itâs time to take a close look at them. Theyâre probably due for a change.
Before rotating your tires, always refer to your vehicle ownerâs manual for rotation recommendations. If no rotation period is specified, tires should be rotated approximately every 5,000 to 8,000 miles. Many vehicle manufacturers recommend replacing all tires on the vehicle at the same time. This makes rotation even more important for maintaining uniform tread depth and optimum tread wear of the entire set.
