True weight savings with super singles

Another thing to consider is that if you get a flat with a hazmat load, you're sitting anyways.

400K+ on a single = how many miles with duals? I'm guessing at least half, if not more.

 

2 years in a row in NORTH AL. TOO.

 

I ran super singles on a T660 running I80 coast to coast doing reefer work as a company driver.

I didnt have any problems with them. Tires were the Michelin X-One, XDN2. I dont know what cost savings they gave vs regular duals. But the ride was nice. No concerns on traction,.. I ran in all weather, snow, ice etc.

The truck itself was a 2008 T660, 475hp C15, 18 spd with 3.25 rear. Truck was always running near gross. Governed at 70 mph. I ran with cruise maxed out all the time. Truck Averaged 6.27 MPG.

Beyond that, I couldnt tell you.

Are you saying you only get 200k mi with duals?

I've got almost 400k on the tires on my rear axle,.. and should see another 100k easily before I replace them. Cheap tires too,.. Hankook DL07's.

We put ss on our hopper bottom trailers. It saved us 400 pounds.

 

when spec'd from the factory on a timpte grain hopper, only a 300 lb savings is realized. I'm told this is due to a heavier axle for the wide based rubber. This is the smaller size wide base, compared to lp 22.5's

 

I pull a tank. The sloshing really takes a toll on tires. Brakes. Suspension components. Etc.

 

If you have had a blow out, you could be stopped for running with a flat tire. If you are loaded, unless you are talking about a few miles, you would be crazy to run singled out. In most cases, if you get a flat on one of the duels, you should be sitting on the side of the road until the tire is fixed.

 

Even though I run wide based, and really like them, I have always advocated that anyone wanting to switch a truck over, it is probably not worth it. I ordered my truck from the factory with wide based. I think it is more practical to do wide based out of the gate instead of making a switch later. Especially if one finds out it won't work well for them and they have to make the switch back to duals. There are several ways to trim weight, and tires are only one. there are many very low rolling resistance standard tires that can offer better fuel economy almost to the level of wide based rubber, so the wide based offering the best fuel economy is harder to justify now.

As for blowing a wide based tire, it really comes down to two things.... improper tire pressure and speed. those two things, combined, will take out a wide based tire. If you don't want to air your tires properly, and check them frequently, and want to run poll position at Daytona, then wide based are probably a bad idea.

 

Going off road a lot like we do is also a bad idea for wide based tires. the exception to that is the 385 tires that we run on the belly dump trailers. With these big balloons they tend to ride up the pile where duals tend to sink in deeper. Now I have seen a 385 blow last summer and that sucker sent the mudflap on the back of the trailer 30 feet into the air.

Bellydumps and steers are the only thing I would run singles on for what I do.
