So I purchased from Craigslist the steelies rims with tires 215-65R-17. They are brand new takeoffs from a Chrysler 300. I paid $225.00. The difference in my Sport Trac is simply remarkable. Granted I was running 20" rims with way oversize tires. The tire shop that put the new wheels on for me said it was close to a 100lb per wheel/tire difference between my old wheels and new wheels(I'm sure this was exaggerated but the point was made). The performance with the new wheels was shocking to me, I had gotten so used to the old heavy wheels. Incredible felt speed/power increase, brakes grab significantly harder and I can complete a U turn without having to back up three times to keep the tires from rubbing. I am so glad this worked out for me. So far the only problem I can see is that the wheels are 17". This appears to be an unusual wheel size. If anyone has a source for either 17" full moons spun stainless steel or 17" Ford factory centers like above or Ford baby moons like on the police cars please post a link or let me know the source.
Thanks guys!
