20 inch wheels - Ford Forums

I'm looking to put some 20 inch wheels with 39.5 inch tires on my Excursion. But I'm not sure if they would fit. I have a 6 inch lift and currently running 35's on it.
If you have any idea if they would fit please send me a response looking to do something real soon. Also any pics.

Thanks, Lee

It depends on the width of the tires in question, depending on backspacing of course, and how much travel you have available. If you can manage, put one of the front tires on a hill until the rear axle is at, or in the air. Then the truck will be on a good angle for you to measure accurately how much extra travel over the 35's you have. Also keep in mind that running close to 40" tires will put added strain on the transmission and drive train components. Upgrading to at least a 4.56 axle ratio would be advised, if you're not there already. Check out Ebay for some lifted F series trucks. there are lots!
