Tires For and FX4
 

I have a 2003 F-150 Fx4 I bought this truck used and it already has some stuff done to it. It has rancho shox I know and I think it has leveling kit because it sits higher than my buddies truck. I just bought **** Cepeck 16's. Anyways I wanted to know what are the biggest size tires I could put under it stock or with a 2" leveler kit?:confused:

new Plan
 

I changed my mind about the rims and I gonna take them back and keep my 18s but please help out guys I'm really new. What would be a good size I've heard tales of people putting 35s on their trucks with lil modification?

Hey, where are you in Korea? I was at Osan with the RED HORSE. Anyway, if you don't want to get into too many mods, a 2in level and 33's would work great and would not rob you of much power.

Your best bet is to fit 33s. You don't have to have any lift, just a little trimming. 35s take a little more work and money...

Im at Osan right now. On duty as a matter of fact. anyways So yeah I could fit 33's tops on my rig because I've seen alot of guys with 33's and all of them look stock.

Yeah, you can easily fit 33's on a stock 97-03 4x4.

What is the exact size should I go with if I use my stock 18s? Isn't like something something r18?

Are you sure they are 18's? THe 97-03 4x4's came with 16 and 17 inch wheels. Only the Lightning came with 18's and the Harley Editions came with 20's. If you have 17's, I'd suggest a 285/70-17 (33x11.50), 305/65-17 (33x12.50) or a 295/70-17 (34x12.00).

My truck came with the FX4 Luxury Package and it has the alloy 18s

You must have an aftermarket conversion package as the FX4's came with 17x7.5 inch wide wheels. I'd suggest a 285/65-18 (33x11.50) or a 33x12.50-18 tire.

Actually your entirely right my bad for doubting you. I have 17 alloys the year after mine went to 18s.
