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.
The first two digits are the week, and the second two are the year the tire was produced. RV tires age out before they wear out in most cases. Once a tire gets to five to seven years of age, they should be inspected by a tire professional annually for signs that theyâre failing. The industry generally agrees that after 10 years, especially when the tires are heavily loaded, they should be replaced, regardless of wear.
