I've searched hi and low for the answer to my tire and spacing issues-2006 DRW 4WD
 

I've searched this forum for more than a month, as well as other places, and spoken with the local tire shop, and I cannot find the right answer.

2006 F350, DRW, 4WD. I am adding +2 1/2" springs in front, possibly one leaf in the rear to bring it up a little.

I am going to run 315/70R17s on the stock rims. I do haul fairly regularly, but never more than 10,000. I obviously do not want the tires to rub.

I've been told/read, no spacers needed, 2" spacers needed, 2 1/2" spacers needed, and even 3" spacers needed.

I will either machine or buy steel hub-centric/wheel-centric spacers, and of course high quality studs.

Can anyone give a definite answer as to what spacer is needed? If they are readily available, I will buy. If not, or they are crazy expensive, I will make them.

I appreciate any/all help. This has been nearly impossible to figure out definitively.

And if the correct answer is out there, I apologize. I sure haven't seen it.

F'n-100, Does your truck have the OEM camper/tow package? My 2006 Ford F-350, SD, CC, 4x4, dually, XLT, 8 ft bed, 4 MKW Model 26 Dually rims, 3 OEM rims, 7 Toyo Open Country A/T II LT285/75R17E tires. Lifted 6 inches. ProComp ladder bars, Skyjacker brake lines, Fox Racing Shocks w/reservoirs, Super Springs Anti Sway Stops, OEM truck camper/tow package. Preparing truck for installation of a 2003 Lance 1161 truck camper. Original OEM rear wheel spacers.

So 285's fit on stock wheels without rubbing each other. That's good to hear. Can you post a picture of the back of the truck showing the spacing between the tires? I would greatly appreciate it.

dual wheels66, I was running ProComp Xtreme A/T LT37/13.50/17D discontinued as of 4 yrs ago. MKW Model 26 rims discontinued. I am unable to post any photos at this time. The right front ProComp tire sidewall torn up due to blowout at 45 mph on 1 Nov 2012. Look at google search Ford F-350 Dual rear wheel spacers. You might have some luck.

I really don't want to use spacers. I am looking to fill up the wheel wells a little more without a lift, the stock tire look so little. I was looking at he 265's and thought they would work on stock wheels. I thought 285's would rub each other and that's not a good thing. I am in no rush for tires, these factory Generals are a nice tire, very pleased so far. I have just over 8,000 miles on the truck so I have a little time yet.

dualwheels66, the rear spacer not only keeps the tires separated, the inside dual is
mounted / bolted to rear disc brakes/axle.

dualwheels66, I pulled off my outside dual today the spacer that is on my F-350 is as
follows:
Spacer 3 inch width
Spacer with small flange over axle 3-3/4 inches
Spacer with studs total width 4-1/2 inches
The rim size I am running on the Ford are 17" 6.5J 8 Lugs
I hope this will help.

Ok thanks bens170, I don't think I will be running a tire that wide. I will probably stick with the 265 series.

dualwheels66, do your research and ask questions also talk to reputable tire and repair
shops dealing with your Ford truck, also possibly Ford Motor Company. Take care and good luck.
