I have a 2008 F150 FX4 with P275/65R18 on. I just had a level kit put on and am looking at getting somewhat bigger tires. I know to get big tires I need to purchase wheels, but I am using the factory FX4 wheels for know. Any ideas on what size to get to make it a little bigger? Thanks for the help.

 

275/70/18 is 1inch taller same width than stock. 285/65/18 is 1/2 inch taller and wider than stock. After
