I recently ordered a Supercrew 4x4 XLT 5.4L on 12/13/00. I wanted the 10 spoke 17" rims and was told that I had to add the offroad package to get them. When I went to order they told me the wheels were dicontinued. TO make a long story short, I went with the 16" 5 spoke wheels, even though I don't really care for them. I'm thinking about ordering aftermarket rims and tires or buying OEM 17" 10spk off Ebay. I really like Yetiman's setup 16x8 285x75x16. My question is, will that size dog out my truck and will I have to change the gears?
