I am looking at buying some wheels and tires for an 05 lariat. I was wondering can I fit 33's? I am planning on installing a leveling kit this week.

 

I'm not positive. I know I have seen some new F-150's with 305/40-22's which are basically a 32x12.50-22. I'm sure the rear will fit even with lowering shackles.

 

I've got 305/35R24 tires on my 2001 4x2 Supercrew without problems. I even have the 2" lowering shackles on the back. They are larger than 305/40R22's at about 32.4" overall diameter. An extra half inch wouldn't make a difference on my truck, so if you have a 4x4 you definitely won't have a problem. Not too sure about the new body style though, but it looks like it sits higher stock than the older body style.
