Hello,

I have been searching for quite a while now to find answers, although there is a lot of information, I cannot seem to get the answers I am looking for. Every time I find what could answer my questions I see another post that contradicts what I just read unfortunately. I have a couple of questions though. I want tires that are bigger, maybe even wider if possible, with aftermarket rims (MT, Envy, Raceline etc.):

Stock 2015 Ford F150

• 4x4 Supercrew
• 3.5 Ecoboost
• Sport/FX4 Packages
• 275/65R18

Questions

1. No Leveling Kit

• What is the max tire size I can have with aftermarket rims (18")?
• I want the tires to stick out a bit as I am getting Bushwacker Fender Flares (1.5"). What level of backspacing do I need?

2. With Leveling Kit

• What leveling kit do I need to make the front as high as the back?
• What is the max tire size I can have now with aftermarket rims (18")?

Note: All of this is really out of my area of expertise so if I haven't provided enough information please let me know. The research I have done led me to post here to confirm my questions. I am trying to give my truck a similar look to the one used as the display model here: http://www.bushwacker.com/fender-fla...black-20935-02. Tires on that truck are 35x12.50R20.

Thanks
