about how much lighter are 15x10 aluminum wheels as compared to 15x8 steel wheels? i have a feeling its a lot, which is probably killing my gas mileage. so i'm thinking about buying some new wheels.

also because i have the fabtech spindle lift in the front, would these wheels fit? i'm not sure because of the backspacing. i think its no more than 3.75" backspacing for the spindle lift wheels

one more question. my old stock 16" sport wheels and tires are sitting in the backyard, so I want to sell them. how much should i sell them for?

 

just weighted my old steel 15x8 they were 26lbs the published weight per mickey thompson's web site for my 15x10 sidebiters is 28lbs & m/t classic2 are 20lbs each . The weight will probably vary per mfg & style cuz the.

 

wider aluminums are really heavier than steels?

 

Not all of them are mine were tho. As i said above it will vary with design & mfg.
