In short, net profit is the most comprehensive profitability metric, encompassing all of a business's positive and negative cash flows. A company's total assets can easily be found on the balance sheet. The ROA formula calls for the average total assets, however. Because a company's asset total can vary over time due to the purchase or sale of vehicles, land or equipment, inventory changes, or seasonal sales fluctuations, it is important to find the average total for the period in question.
Rolling resistance is the impact the road has on the tires, and how it affects drivability. If you change the features (size and width) of your tires, it will then influence the interaction it has with the road; thus affecting the gas mileage. This is where tire width can begin to influence gas mileage. Many people believe by changing the height of a carâs tires, they can increase its fuel economy.
I just switched to 235/85/16's. They are a tiny tiny bit bigger than the 265/75/16's. I believe this size is great for having the advantages of the bigger tires, but also not being prone to the MPG loss from upgrading to a 32 tire.265/75's is going to have more rotational mass than 235/85's.he speedometer is DEAD on with the 265/75's, but the odometer is reading slow. I noticed this on a road trip with my GPS; I reset both the 4Runner and GPS odo at the start of the trip, and the GPS was reading 30 miles more out of a 400 mi trip. Not too much of a difference, but it's large enough to irk me.
