theflystyle Posted June 15, 2006 Share Posted June 15, 2006 I am currently tire shopping for a good All Season tire. During my search I have narrowed it down to three tires in which I will end up choosing from. One thing I did notice was the weight varies anywhere from 21lbs to over 25lbs per tire. I tried to find some info about how a lighter or heavier tire may effect mileage and any other aspect but came up a little short. PS ( I am 90% sure I will be going with the P Zero Nero M+S which if you would like to know weighs the 21lbs. -Ali Link to comment Share on other sites More sharing options...

High mileage tires are harder and will have less rolling resistance. Lower mileage tires are stickier (softer) and take more nergy to move. You are basically taling 12 lbs here, so it would have a negligable affect. Your right foot can vary gas milage by 5mpg around town easily, so i wouldnt worry about it. http://www.treehugger.com/files/2005/05/low_rolling_res.php nipper Link to comment Share on other sites More sharing options...

keltik Posted June 16, 2006 Share Posted June 16, 2006 Just sat a physics paper on this, theoretically it takes zero energy to keep wheel spinning - no matter how heavy it is. However - the heavier the tyre is, the more energy it will take to get it up to speed. Choosing a lighter tyre for MPG would have about the same effect as putting alloy wheels onto your car. Not worth worrying about really. But youve gotta ask yourself WHY is the tyre lighter? Maybe its not built as strong? KELTIK Link to comment Share on other sites More sharing options...

Tis will explain exactly what you are saying. sorry im too tired to discuss this one myself. http://draco.acs.uci.edu/rbfaq/FAQ/8b.14.html http://www.tirerack.com/tires/tiretech/techpage.jsp?techid=29 i love tirerack nipper Link to comment Share on other sites More sharing options...
