I am considering swapping the LTZ Tahoe 20's and 275/55R20 Toyo Proxes S/T that are currently on my half ton for a set of OE 17's with 275/60R17 Nitto 420S. The current combined weight of a single wheel and tire is around 80 lbs (about 40 each wheel and tire), maybe a couple lbs higher. The combined weight of the 17's would be about 60 lbs each (37 tire, 23 wheel).
Anyone have any estimates on the net effect of dropping 80 lbs of wheel and tire weight would have on ride, handling, acceleration, and mileage? The current ride quality is bad, mileage is meh (15 city, driving "spiritedly"), and while the truck feels quick after I get it rolling, it just feels "heavy" starting from a dead stop. I'd probably have to regear from the current 3.42 to either a 3.23 or even a 3.08 (assuming I could find a set for the 8.25" front diff) to keep the revs down at freeway speeds. Not sure if it would be worth the effort and expense, but I figure it's worth exploring.
I know unsprung weight and rotating mass play a large part in suspension dynamics, and I feel like 20 lbs per corner is a pretty big drop that might net some decent gains all around, but I have no idea how to quantify this. Any ideas or experiences?
