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.
BMW allows up to 15,000 miles between oil changes, but that is too long to wait to rotate the tires. Unless you drive fewer than about 7,500 miles per year, you should probably rotate tires every six months or so.
