What is tire balloon size? I have been riding motorcycles for over 40 years and never heard that term before. In general, higher pressures give better fuel consumption.
Cast iron is a piece that was made by pouring molten iron into a mold.
Cast iron is made by remelting pig iron, often along with substantial quantities of scrap iron and scrap steel, and taking various steps to remove undesirable contaminants such as phosphorus and sulfur. Depending on the application, carbon and silicon content are reduced to the desired levels, which may be anywhere from 2% to 3.5% and 1% to 3% respectively. Other elements are then added to the melt before the final form is produced by casting. Or perhaps you mean cast-iron cookware? See links below.
yes it can and will, more traction takes more for muscle or rpm or gas, for the tire to turn. BUT rest assured the cost is completely marginal meaning it will cost a fraction more to move that tire! (YOU WILL HARDLY NOTICE IT) anytime you change rims(more width or less) it affects fuel consumption, but tire heighth will actually hit you harder, say some mudders on a 4wheeler lol will definitely use more fuel YES TO BELOW, EXCEPT YOU SAID WIDER NOT BIGGER, also to roll on the highway BIGGER tires save fuel but driving through town uses more fuel to get those BIGGER tires moving from stopping to rolling (at that size difference no speedo chage is required, but taller tires do require a speedo change so your spedometer is correct and your abs is still reading correctly
