The time has come to replace the tires on my Truck a 2008 F150 FX4 Super crew. Currently I have stock 275/55/20 tire / rim combination on the truck. I am considering the Goodyear Duratrack 305/55/20 or the same in BFG AT/KO's. My question is will they fit without modifying the vehicle? That means no spacer's, lift kits, tweaking, cutting etc. If they would not, how big can I go?

I have searched and searched the forums and internet, but I have yet to see an answer that will convince me to lay out the $,$$$ for the tires in the hopes that they will fit.

Any ideas or suggestions?

Thanks

 

They will fit, but have read that the additional width will cause them to rub the control arms at full turn with the stock wheels. Darrenws6 has 33x12.5 on 20s with no level. Basically the same size as u list (33.2x12). Pawpaw has that size on his new truck and had them before he put on the level, although I believe its an 11.
