35's and towing. Will it improve loaded mileage?

[BKopp]

I'm sure this has been discussed before but can't seem to find the definitive asnswer. To start out my rig I pull daily is my cclb 2008 f350 4x4, full ******s, studded tuned by minimaxx in tow setting, torque shift trans and 255/80/17 tires. Trailer is 20 + 5 tandem dually, mostly pulling my 10,000 lb skid steer around. With my truck trailer and skid steer with transfer tank of fuel I'm at 26,260 lbs. I get around 8 mpg with it.

My question is would running a 35" tire improve my mpg's? I need to get tires soon and want to know for an informed decision.

I hauled a load for a buddy this weekend with an enclosed 24' gooseneck. Empty trailer up to Chicago I averaged 12 at 72 mph. I was loaded with about 8 tons in a 7 ton trailer. So I took it slow 62 mph on the way back which is at around 1800 rpms I got better than 10 mpg on the way back. Which is why I was thinking 35's would drop my rpm's and improve my mpg's.
Anybody have an answer or input?

Speed kills MPG. How fast do you pull your trailer?

Your buddies trailer......8 tons = 16k + 4k? (trailer) = 20k. Then add the truck (8k)...total 28k (buddies trailer and your truck).

Basically you slowed down and MPG went up. Also you have to factor in wind resistance of the trailers and possible weather conditions.
