I have a 03' XLT supercab and am needing some new tires. I have the stock Goodyears on there now but am looking to upgrade to something more aggressive. I am looking at getting the BF Goodrich All Terrain tires but don't know the first thing about tire sizing. What size would I need to buy? THANKS!

 

They will be a huge improvement. If you have a 4x4, I'd go with a 285/75/16, 295/75-16 or 285/70-17, 295/70-17. If you have a 4x2, I'd go with a 265/75-16 or 265/70-17.
