Wheel Spacers?

[MacbooknMyTruck]

I'm looking to put some 2006 or 2008 OEM 20" wheels on my truck and many people have told me that they wouldn't fit without a 1" wheel spacer. Where can I find those for my truck? And are they safe to use while hauling heavy loads? THANKS

I wouldn't use them for hauling heavy loads. I wouldn't use them period but some people say they are ok. Plus 1 inch is a pretty big spacer and the wheels will stick out a ways. So I personally would say don't do it specially if you tow. My .02
