The 4 lbs number sounds off a bit for an extra inch in width. I did a lot
of research in looking for my 17x10s, and found that going from 8 --> 9 -->
10 --> 11 added one lb for each additional inch of width. Pretty
consistent among mfrs. Going from 15 --> 16 --> 17 diameter made for a lot
more variance.
Increasing the width should not add much weight as it increases the amount
of material in the (fairly) thin rim halves. Increasing diameter means
that the thicker/heavier center section will get bigger.
This will probably vary on construction method - 1-, 2-, 3-piece, forged vs
cats, etc.
For my web page on the lightweight wheels I found out there, go to my site
(URL below), and go to Upgrades --> Wheels & Tires --> Lightweight Wheel
Comparo.
