ok had an accident two days before the new year well anyways trucks in the shop guy called me said that the two wheels on the driver side might be bent do i wana do aftermarket wheels or stock so i said aftermarket and of course the wheels are 18's and my stock are 17's so need new tires anyways my question is what size tires can i fit on my 2005 f250 Fx4 i heard i can fit 35's because it has the Fx4 package

 

325/60-18 is a 33inch tire, I'd mount on AT LEAST a 10. 285/70-17 is a 33 that can go on a 9 or 10. For more tire sizes, I'd check out Summit Racing's website, they're great for hunting around for stuff, getting what size you really want then shop around.

Oh yeah, personally, I wouldn't do anything more than a 33 without a lift, but then I also believe a rim should be VERY close to the tread width.

 

you can fit 35s with a leveling kit

 

You would need a 2.5" spacer up front and F350 blocks in the rear. FX4 don't mean it sits any higher. Just means you got some stock Ford shocks with Rancho stickers on them (seriously, they're the same as all the trucks), and some good skid plates.

I'm running 315/70/17's on stock 17x7.5's with a 2.5" spacer up front and 350 blocks in the rear.

You could EASILY fit 285/70/18's. They would probably look a little small though.

 

Is the 2.5" spacer on the 05 & up for the track width change? I heard about this but I thought it was if you were running newer hoops on an 04 and older SD/Excursion. Too many details to remember

 

It's a coil spacer, just pushes the coil up or down, depending on which type you get. It's not a width change, vertical change. When you do this, the axle will move to the side a little bit. The correct way to do it would be to add an adjustable track bar.

I've been looking at doing a nice 3 link setup in the front with an adjustable track bar and doing the track bar flip.

Anyone else flipped their track bar?

 

My reading comprehension skills suck as usual, I confused lift spacers with wheel spacers.
