I bought 20"x 10" wheels (MOTO 951 chrome) for my 2003 F-350 FX-4 regular cab 4x4 truck and already have the tire brand picked out (BF Goodrich T/A O=or TOYO) but need help with the size. I have two that I am debating. I am going to put a chart up of my stock tire vs. the other two. I want to know what all you guys thought. Please give me some direction here. I do most of my driving on the highway (95%) so the only thing that will mark the wheel (http://fordtruckworld.tenmagazines.com/ipg.asp?scid=347)is a curb. I also would like to know the fitment issues (rubbing) as well as the handling issues. Any picks would help too. Both tires don't match the load rating on my stock tires but was told these would be fine? All information was gathered from 1010tires.com. Thanks and be well. Joe
