Tire size on hauler for best fuel mileage?

The best thing you can do to improve fuel efficiency, is not tow. The second best thing you can do is slow down.

Yes slowing down has made a significant difference, but now in a dp and I find a sweet spot between rpm, turbo boost and speed a bit different speed is not all to fuel economy.

So your towing the Wolf Pack 325PACK13 with a 2500 diesel. Where were you when I asked about upgrading to this 5ver and towing it with my F250 4WD diesel? The tow police here went apes@!# on me. Hows your truck tow with your trailer? Any issues? Scale weights?



As for tires, I used to tow with 35" tires but went back to LT275 / 75R 18 BF Goodrich T/A's (33") rated at 3640 lbs. each. It tows so much better with these than the 35" tires.
