Wheel / Tire size, offset, etc question
Hi folks, I've found a lot of great info here, but just needed to clarify a couple of things.
I've currently got an '03 F250 FX4 with the King Ranch package. It's got the King Ranch 16" rims. Picture is below.
I'd like to go to a bigger tire, like a 305 or 315. My understanding is that my current rim is 16x7, so I'll need a wider rim.
Also note that I've purchased the Donohoe Racing 2" Mini-Spring Pack to level the front.
I really like the Moto Metal rims, and I'd like to stay in a 16" rim if possible, like the Moto Metal 950's which come in a 16x8. If necessary, I'll go to a 9" rim, like the 17x9 size of the Moto Metal 951's.
So that's question 1. (for a 315 tire, do I need larger than an 8" rim).
Question 2 would be: For the Moto Metal options I'm considering, what's the offset and lug spacing I'm looking for?
I sure value your feedback, there sure are a lot of knowledgable and helpful folks here!
Thanks in advance!

Hey Tx,
You don't NEED a rim wider than 8", unless your going w/ a tire wider than a 12.50". A 10" might give you a flatter footprint but it wouldn't be necessary. If your using a 305/75 or a 315/75 you'll be fine w/ an 8" rim.
I believe your lug spacing should be 8x170mm. This is what my 04 is anyway.
And your offset should be somewhere between 4.25" and 4.50". That combined w/ an 8" wide wheel and a 12.5" tire, will make the tire stick out just beyond the outer lip of the fender.
I hope this helps man!! Good luck and take pics when your done!!

Wow sweet trucks everyone!!!! I cannot wait till my 150 4x4 gets delivered, its been 4 weeks and any day now I'll be posting some pics.
I'm definatly going to level her out....with what I think will be the AS 2.5 kit, so many choices?????
Anyway I'm sold on the Moto Metal 951 chrome 18x9's and BFG AT 305/65/18 does anyone have this combo currently on their truck. I'm really concerned about the tire sticking out past the fender, should I go smaller than the 305?????
Thanks for any comments suggestions.
