Hello,
I have an 04 FX4 F-150 with 18" stock wheels. I plan on getting a leveling kit and wanted to see what the biggest tire anyone has put on this combination. From what it sounds like a 305/65/18 may be the limit and some say they get rub. Please advise.
Thank you,
Mark

 

Welcome to the site. This question has been asked about a million times. You can fit a 35x12.50 using the OEM wheels but they will rub the control arms slightly at full steering lock.

 

would spacers help so they wont rub but you couldnt tell the difference in appearance ?

 

I agree with Wandell with the 35x12.5 being the largest you can fit, but the 305x65 which is close to 34 inches tall may be a better fit on the OEM wheels. BFG makes this size in an all terrain if that's what you want. BFG makes a 325x65x18 (35x13) or close to it but these may rub on the control arms pretty bad.

 

I'd stay away from spacer's.

 

I agree. Spacers are generally a bad idea, especially on trucks prone to vibration issues like the 04-08 F-150's.
