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.
Some tires also come with life wear warranty, meaning they'll have 20k, 40k, 60k + mileage before they need replacing. Too many variables. If you do indeed drive 2k miles a year, then a tire should last you 6 to 10 years before they need replacing regardless of how much life is on it.
