I have a 2004 F-150 Super Cab FX4. I just installed the leveling kit. What are the biggest tires I can install with my stock 18" wheels? I need tire sizes please.

Thanks in advance!

 

I have 305/55-20's (33x12.50) on aftermarket rims and I wouldn't want to go any bigger on aftermarket rims - but there are a number of guys running
35x12.50x18 on stock wheels with a levelling kit and only minor rubbing issues.

 

You can run a 285x65x18 (33") a 305x65x18 (34") or a 35x12.5x18 on the stock wheels, I'd stick with the 305's.

 

I thank you both for your answers. I'm going to order the 305x65x18.

 

What kind of leveling kit did you go with?

 

The 305's are a good choice, I have some with a leveling kit. I still rub some after doing a little cutting......

 

Check out my gallery. Those are 35x12.5r18 BFGoodrich KM2's

I have an Autospring 2.5" leveling kit and there is no trimming at all required. I have also not experienced any rubbing with the KM2's.
