I have a 2008 FX2 Sport 5.4 3:73
I have stock 265/60/18 on it. I don't like these small tires. I do most of my driving on the highway and I want a taller tire. Anyone have an idea what the biggest tire I can run on it?
Thanks

 

You can run a 32" tall tire on a stock 2wd on the stock wheels. try a 275/65-18 if you want to keep the 18's or if you want to step up to the 20's try a 275/55-20. both sizes came stock on the 150's from 04-08.
