I have a 04 single cab fx4. Has leveling kit and has some 275/65/19 tires on it...they look way to small imho. What is the biggest I can go on just leveling kit.

 

275/65/19 19" ?

 

What size is the leveling kit, it depends on that.

You're going to need wider wheels if you want a beefier look. Bigger tires on stock wheels only look taller.

 

You have 19's?
Anyway, as a general rule, you can fit a 35x12.50 using the stock wheels or 33's using aftermarket wheels.

 

Sorry I ment 18..I would like to go to 17's
I have after market moto metals but they don't have a great offset like I want.



To me the tires are way to small for the truck.

 

I think a wider tire would get you the look that you want. What is the offset of your wheels? If it is close enough to stock, you can fit a 35x12.50, which would be a nice, beefy tire.

 

BINGO!! Soooo many guys miss this critical point by throwing XXx12.50's on stock or skinny wheels and then wonder why they don't have that "look". Search for the guys running 10" wide wheels on here; that's what you want and IMO, the minimum width for a 12.5 tire. Especially to achieve that certain look. More critical than tire size by far.
