.5" really worth it

[scape]

i read somewhere that 1 lbs. of unsprung weight removed from the wheel is equatable to 10 lbs. static weight. so 1 lb. dropped from all wheels would be 40 lbs. removed. I don't think this is very 'scientific' but it is something I ran across from a website; don't take my word for it.

keys to remember are, the wider the tire: more rolling resistance due to more rubber on the road/but better handling in turns due to more grip
the larger the rim in diam.+weight: the more rotational force exists-- easier it is to continue going in a straight line/but harder it is for the tire to change directions.
grab a bicycle and spin the front tire in the air, then turn the handles and see what I mean.
as for rim width, I don't think 6.5 and 7 are much of a difference except extra weight and tire selections...possibly less tire roll, but I doubt that

Thanks scape, i tihnk im goin with the 15x6.5 best compromise. I doubt the .5 will make muc dif, and itd be nice to save a few lbs. Thanks again buddy good post
