quote:Going from steel to aluminum will only save $30 in gas for the life of the average vehicle - not enough to pay for the premium of aluminum wheels. This info is from the Aluminum Association who recognize that the only advantage to aluminum wheels are good looks and unsprung weight.

Originally posted by LarryL: Willy is right. Alum wheels would cost far more than a 21 year old Civic wagon is worth. Gas mileage is a game, especially with the price heading for three bucks a gallon. Here's a question. It the higher gear ration from larger tires worth the increase in mass to spin?
quote:Larry, in a small efficient car like you have the parasitic losses of the tires can make a difference of a couple MPG. Use the engineering prowess of the big guys. Buy the same tires used on Toyota Prius, Honda Insight etc. The Goodyer Integrity and Bridgestone RE92 seem by implication to be some of the lowest rolling resistance tires available. Remember tires are 100% engineering compromises. The tires that excel at low rolling resistance are also the poorest performing tires in the catagories that tire enthusiasts generally look at. I saw 2 MPG difference between Integrity and BFG Traction TA but elected to go with the substantial inprovment in handling etc. of the TA. If you are going to experiment for improved MPG I would try fabricating a front air dam and from my experience see a 1-2 MPG improvement on the highway in your car. Note this is not like the useless cosmetic spoilers being sold but a vertical slab from the front bumper straight down to 4" above ground level. Use hard plastic for the lower part of the spoiler and the occassional scraping on the ground is not so bad. Of course put in some good 'ole 0-20 !
