what ? rims unusable ? they have no lifetime. they will last forever if I don't damage them

I am not concerned with any of this, or hypermiling, or anything else along these lines.
I am just saying that MPG's will increase if you use lighter rims, which is a no-brainer anyway due to weight.

I am not going to factor anything else in, or compare the carbon footprint of manufacturing a steel
rim vs an alloy cast and all that tree-hugging crap.

cost benefit x time ?

the yaris handles better (steering is improved), accelerates quicker, stops faster, gets better MPG's, and these benefits are immediate

lessee...
I will throw out a wild guess...I reckon it will be somewhere near 47,000 miles
before I reap the cost of the rims if gas is 3.5 bucks a gallon. good enough if you are
going to keep the car for 100,000 or more miles
