I just bought a 2005 f150 stx flareside and would like to level it but don't know if I should wait until I get bigger tires. Its sitting on 265/65/17 General Grabbers now. Input would be greatly appreciated or pictures of people who had done the same.

 

My 2007 style side had the same size tires you have. After I had it leveled the tires looked very small. My fender flares only made them look smaller. I replaced my tires going with some 34" Toyos. This is what it looks like today...
