Just wondering if anyone would be able to tell me the maximum tire size I would be able to install on a 2003 F150 7700 4x4 supercab. The 7700 GVW package is supposed to be the trailer package/"heavy half-ton" series, and I believe the factory tires on it are LT245/75-R16. I would like to put LT285/75-R16 on it without lifting if I can or very minimal, and some info I found on-line suggest that it MAY work on factory. thanks

 

Fitting 285's on your 7700 is no problem at all.

 

I agree.

 

Sweet!! Thanks alot guys!! Looks like the old F150 gonna see some new meats.
