I came across a factoid on an engineering calendar that said: "1932 (year) Rubber wheels result in a 25 percent improvement in fuel economy for tractors". Is that true? Would a rubber wheeled Farmall H have 25% better fuel economy than a steel wheeled H?
If so, then rubber wheels were a big improvement for our farming grand fathers back during the Depression (assuming they could scrape up the coins to convert to rubber tires during those tough times).
On a similar note, I was reading a magazine last fall that spoke of Michelin having a new rubber compound and radial combination that is showing 7 to 10% fuel mileage improvements on their test tracks. I am just flat amazed at how folks continue to make things run on less fuel.
Anyway, back to the steel versus rubber question, a 25% improvement, do you think it would be that much?
