It's about time to buy new tires, and I thought I'd get some bigger ones now. I have a 2003 FX4, stock size is 26570R17. I'd like to get some bfg mud terrains, but I'm trying to figure out what size tire and wheel combination is the best. If I can get some without changing rims, I'd really be happy. I don't understand how the tire sizes work I guess, because I can't figure out what sizes I can get without changing rims. Someone please help me out. Thanks. You can email me at roy.money@us.army.mil.

 

i would go 285/70/r17. they fit nice and dont rub. they also look a lot better then the stock tire size in my opinion

 

285/70/17's are perfect!

 

Will these tires fit on the stock rims, or will I have to get new ones?

 

they will fit on your stock rims
