Dear All,

I have an 85 Chevy G20 Van. 15" rims. I would like to know what are the lightest rims I could get for this. Alloy? Aluminum? Other? I'm looking to improve gas mileage and have good looking rims. What are the drawbacks of the different types of metals? Could you direct me to websites or the best locations where I could purchase these rims?

Thanks. :)
