How much would lighter wheels help?
I have a 2005 civic non-hybrid. I usually get ~42 mpg. Best is 47. My stock wheels are a beefy 18 lbs each. Would the cost to benefit ratio be in my favor if I got wheels that were 12 lbs each?

I read once that for every pound of unspring weight that is removed, it the equivalent of removing seven pounds of cargo from your car. This is not an exact science and I think may apply more to larger cars with larger wheels, but...
Six pounds per wheel times 7 is almost the equivalent of removing 100 lbs. I'd say that's worth 3 mpg easy.
$250 is cheap. If the quality of the wheel is good, I say go for it.

Also note that this is only true under acceleration. Lifting a pound in the wheels uphill at steady speed is no different than lifting a pound in the car uphill.
A more significant benefit from lighter wheels however comes from reducing unspruing weight, which will produce a softer ride, as not as much force will be transmitted into the suspension over bumps. Improved ride would be an advantage to consider though. On rough terrain, this may save a bit of energy as well, as less will be dissipated in the suspension, but this won't make much difference on smooth roads.
However, I would wager that they way that they achieve such a low weight is by using thin spokes. Aerodynamic turbulence caused by a mostly open wheel will likely offset any advantage from the reduced weight.

There are many types of lightweight wheels out there, Most people prefer this. I truly feel that lightweight wheels are an incredible upgrade, This makes it less likely for your brakes to fail due to overheating.

In my point of view it's most ideal decision and I really appreciate this because now a days hybrids improve fuel economy it is the most advantage of this. When you plan to buy your first hybrid than Toyota prius is the best option now a days.
