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.
Hereâs why doing such an expensive, time-consuming test is worth it. Our last test of 20 regular all-season tire models had tread wear warranties ranging from 40,000 to 100,000 miles. You might guess that the longest wearing tires were those with 100,000 mile warrantiesânot so. A pair of these overachieving tread wear warranty tires rated just âaverage,â the same rating as the 40,000-mile tread wear warranty tire.
