Changing wheels
Bought a 2010 Lariat used, it seems the previous owner changed the 20" wheels and scorpion tires to 18" Ford wheels and Goodyear wranglers.
Question- is my speedo off now. I know the truck had 20" rims when new because of the door sticker, and build sheet.
Thanks in advance for any help.

Use this:
http://www.1010tires.com/tiresizecalculator.asp
The door should say the OEM tires that came with it, then punch in the tire size on there now and it will tell you the speedo diff.

changing wheel size.
Thanks to SEEMANRUN I went to that web site. It seems that the 18" are 32.07" in dia. and 100.7" circ. compared to the 20" at 31.90" in dia. and 100.2 circ. I don't think my speedo is changed much because of the wheel change. Thanks again.

HI SeeManRun... I just recently purchased a 2011 F150 XLT with stock 265/70/17 tires and stock rims. I am looking to put on some bigger tires and rims but am not sure how big I can go on either without rubbing. I don't plan on putting a lift kit or anything in it. I would like to keep it stock. If you could help me it would be much appreciated.
