Question For All The Sailun Tires Owners

[GoPackGo]

I just put a set on my fiver and my super accurate seat of the pants impression after pulling it 500 miles (2 trips) is that I'm getting significantly better MPG (diesel).

I don't keep records; I just watch the Ford DIC. I know those things are not exact but I'm just comparing what I remember from the past, so it's still apples to apples.

Is it because the old tires were run at 80 psi and the new ones are inflated to 110 ? Less rolling resistance ?

What has been your experience ?

YUP same here I did notice a different pulling. Seems to pull smoother

I just put 4 215/75/17.5 Sailun tires on my fiver. I have heard nothing but good things from folks that have them. I replace 4 Michelin of the same size with only 7000 miles on them, however they were five years old. Tires had many cracks and didn't look safe. I contacted Michelin but they were not interested in my problem.

I believe it means "Dash Information Center" referring to the various items that can be brought up on the screen in the center of the dash right between the speedometer and tachometer on most modern trucks.

There is a whole laundry list of items that you can view there such as MPG, trailer connect info and brake info, engine gauge info, engine history etc etc etc. Really kind of neat and I find the info quite useful.

Oldbicuit, what is "DIC?"

[JIMNLIN]

Your mpg gain is typical when moving from a E to a G tire. I noticed a big difference when I replaced the ST load E may pops with the Sailuns on a 16k GN triaxle stock trailer. Running the same hills with the same trailer and the same loads the Cummins/NV5600 could now pull them in a higher gear.

When it came time for me to replace our tires, I researched many different ways to go. I wound up purchasing 17.5" J rated medium duty truck tires and wheels. When all done and said, it was $5.00 per wheel and tire combo more than just replacing the 16" tires. This tire and wheel combo is good for 6005 pounds each. Using the inflation chart to get the pressure for the load, I inflated to 80 psi which was good for 4500 pounds per tire. With the first tow with these tires to Kansas City, I have made this trip to the speedway several times before, I was down almost 2 mpg both ways. The tires were 20*-25* hotter than the truck, which I have never experienced before. I inflated them to the side wall pressure, 125 psi for max load, before our trip to Florida. Now the tires run 5*-10* cooler than the truck and my fuel mileage is back where it used to be. I have always run max pressure up until I installed these tires, with what I have experienced, I will continue to run what the side wall indicates.*

Regardless of the mileage, I like the way the camper feels behind the truck. I've had the Chinese junk, Sailuns and GY G614s and the 14 ply tires stop the soft, "lumbering" feeling of the trailer behind you. Much more stable feeling in my opinion.

DIC isn't accurate enough to display the 'slight' increase in less rolling resistance.

Wind drag has more of an impact.


My mileage is always better when towing my 5vr right after I have washed and waxed it.
Especially if I have done the truck also AND recently changed oil/fuel filter and air cleaner filter

Steel ply sidewall with less flex, creates less rolling resistance. Tread pattern is also better for a trailer. Chris

No real proof but I think less rolling resistance has very slightly improved mileage.
