What is the size of the stock 20"s. Are they 20x8.5?

Would a set of 305/55/20's look good on the stock wheel or would it be better to get some aftermarket wheels?

 

Stock OEM wheels are 20x7 They may even be 20x7.5 but not larger.

 

I thought the stockers were 8.5"

They def are not 8 or 8.5. I just sold mine and when I was cleaning them, they were stamped on the inside stating that they were 20x7's Like I said earlier, they may be 20x7.5, but I'm leaning more towards 20x7. I'm sure Wandell will chime in sooner or later and let us know. The link that you provided has them list incorrectly IMO.

 

They are 20 x 8.5,I just pulled all my wheels off to wash the brake dust off about two weeks ago.http://cgi.ebay.com/ebaymotors/F150-...QQcmdZViewItem

 

Here's more listings that have them at 8.5":

But yes, a 305/55-20 would look good on them. However, they would look even better on some aftermarket wheels.
