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.
Valve stems (and tubes, for tube-type tires) should be replaced every time a tire is replaced.New tires typically have a slippery surface. Take it easy on your first 100 miles as the tireâs surface âscuffs inâ and provides maximum grip. This break-in period also gives you time to adjust to the difference in how the new tires feel compared to the old, worn tires â like getting use to a new pair of shoes.
