For this discussion we will look at the costs of increasing the number (and quality) of outlets in the average home, including both 120 volt and 220 volt equipment. The average number of outlets per room in a 2500 square foot home tends to be two or three in each space.
A tire (American English) or tyre (British English) is a ring-shaped vehicle component that covers the wheel's rim to protect it and enable better vehicle performance.
Today most tires are pneumatic tires, though typically still referred to as just tires. The word pneumatic simply means an item that uses air. Tires work because they have tread on them. Tread is the raised patterns that appear on the top of a new tire, which often appear to zigzag around the tire. The tread helps the tire gain traction on the road to prevent it from sliding.
