Hello everyone new here to the site I have a 02 screw fx4 want to know what is the tallest tire i can fit under my truck without any mods. abd any tire suggestions would be great. Thanks

 

If you use the OEM wheels, you can squeeze a 315/70-17 (35x12.50) on there. However, it's an extremely tight fit and you will have some rubbing on the frame at full steering lock. I wouldn't go that large unless you plan on a lift in the near future. I'd stick with a 33 inch tire like a 285/70-17(33x11.50) or a 305/65-17(33x12.50).
