i have a 2004 Ford F150 4x4 FX4...i am currently running 18" tires...Could i possibly go down to a Size 17" rim with this truck..what will i be sacrificing as in towing and all...

 

Are you running factory 18" wheels? Why do you want to downgrade to 17"? Wont sacrafice anything, will probably just gain a little weight, smaller rim with a thicker tire full of pressure I would imagine would have more weight in it.

 

beware i ve read not all 17in rims fit on our trucks with the brake calipers and what not, so make sure its been done before lol

 

alrite thanks guys..

 

My truck came with the 17 inch wheels. No big deal. They run just fine. You won't be losing anything when it comes to performance. Depending on your tires, tire size, and overall weight, your mileage may change.
