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 conventional wisdom is that your road bike tires last anywhere from 1,000 to 3,000 miles. High-end tires should last at least 2,500 miles. Racing tires, which are designed for speed and high-performance, may need replacing after 1,000 miles, but tough touring tires can last as long as 4,000 miles. If you are a commuter who rides on asphalt you may have slick or inverted tread, which improves the road-life of your tire.
