I have a 2005 F150 STX, I have a leveling kit on it. I have 17x9 rims, what is the biggest size tire that I can have. I'm a complete idiot when it comes tire sizes.

 

1. What size is the level?
2. What is yer gear ratio?
3. How do you plan on correcting for Speedo/odo/shift point errors?
4. Are you saving up fer new front-end components?
5. IMHO - go no more than a 33" tire, and no more than ~10-11" wide. You only have a 4.6 - so not much grunt to begin with.
6. Power loss will suck.
7. Mileage will tank.

8. A tool fer ye to bootstrap yeseff: http://tire-size-conversion.com/tire-size-calculator/

9. Display some Manners, perhaps?:



g'luck.

 

That's funny right there...😂
