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.
I have used my trailer for 5 summers. The tires probably have around 5000 miles or so on them. Posted By: Chuck&Gail on 01/24/12 06:44pm. I change mine when they get to be 7 years old per the DOT code (trailer age often means nothing cause tires could be old when instralled) or they are worn out.
