Lately I've noticed quite a few more trucks and trailers running super singles instead of duals. What's the benefit or reason to choose one over the other?

 

That's an interesting answer to a question about tires, Mike. Got a little case of turbo obssesion, I see.

Super singles are used where the empty weight of the truck/trailer is very important. You'll see them a lot on fuel tankers. Less weight in the rig = more gallons of gas going down the road. It's the same for other cargoes that are heavy but not too bulky. You won't see them on a Frito-Lay truck. They also help economy, but not a lot of fleets run them for that reason exclusively because the savings in fuel don't offset the tire cost. Duals are much cheaper to buy, and if one of a pair blows the truck can be limped to a safe place for service with no damage to the rim.

 

Good catch.
You can tell I definitely have turbos on the mind.
I got all excited by the 'Super Singles'
Too little sleep will do that to a guy.
I'll fix it. LOL

 

I was reading a tire study a couple of weeks ago and I remember it saying that super singles are becoming more popular because if the diameter of your duals is off just a little bit you end up causing serious wear that just compounds until a tire fails. Example: If the inside tire is a smaller diameter, it is going to "drag" as the outside rolls normally which causes major heat buildup until it fails.

 

Where did the info on where to get these go?

 

There never was any info on where to get them.

 

www.chromewheel.com I e-mailed them about three weeks ago for a quote on their 8 lug directional float wheels. Haven't hear from them yet. I guess I'll have to call. Also American Force Wheels have them. http://www.americanforcewheels.com/super.html Any Alcoa heavy truck dealer should be able to order the wheels, then you would have to purchase the 8 lug to 10 lug adapters.

 

I worked for a fleet that used the 445/50/22.5 Michelin X-ONE XDA's on some of the drive axles and trailer axle on their semis. They went to the for the mileage, but since i had to change them I actually prefered them over the normal 11r22.5's they were running. They don't look it but they actually were easier to mount and dismount on to a wheel, they seemed to "give" a little. Plus when a truck came in for drive tires to be replaced you only did four instead of eight.
