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.
However, since theyâre smaller and more compact, theyâre missing out on two key aspects of a regular tire: durability and stability. Most of these spare tires have a limited top speed of 55 mph. You can expect to get about 50 miles on a spare tire like this, and some are rated up to 70 miles. That should be enough for you to find a mechanic who can patch up your flat, or a tire shop where you can replace the punctured tire.
