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.
The word tire is a short form of attire, from the idea that a wheel with a tire is a dressed wheel. The spelling tyre does not appear until the 1840s when the English began shrink fitting railway car wheels with malleable iron. Nevertheless, traditional publishers continued using tire.
