Super Singles

The truck I drive has super singles. They are a feww hundred pounds lighter than regular duals and they also say you can up your fuel mileage by running them, I couldn't tell you if they do or not. The truck I drive runs smooth on them though, I don't really have any complaint's I guess. One thing though if u have a blowout u can't limp in somewhere to get it fixed, youre pretty much sidelined when it happens.

 

You'll see alot of singles on gasoline tankers for two reasons. 1. They are lighter which means more product. And 2 the axles are wider which lowers the center of gravity. When you do that it reduces the rollovers. No state that I know of counts the tires, it's always the axles.

When we ran them in Nevada the state would not allow the singles on the drive axles. We had truck and trailers that had 4 axles on the trailer and we had singles on all our units. With the 4 axle trailer you can move the truck when one goes flat but you've got to creep along and not very far. I personally like them and have never had any problems on slick streets or I should say any more of a problem than the older duels. Then once ABS came on the problems were all over.

 

Less rolling resistance + better mpg. With my tractor and trailer, all supers, mpg's went up 1 to 1.5 mpg, depending on the load. As far as wear, my trailer (flat) has 250,000+ miles. They will need to be replaced in a few more months. The tractor has 130,000 miles on em. They easily have another 100,000+ miles left on them. I have the X ones.

Here she is, and thank God it is PAID FOR!

A major side benefit of Super Singles is the brake drums get more airflow making them more resistant to fade.

 

i was always told less rolling resistance, less weight, might last longer, and better fuel mileage......i rookied out in the winter on them - had no problems....I like them.....unless their flat....only had one go flat before the company changed it.....

 

You save four hundred pounds on a set of drives, and another four hundred pounds on a set of trailer, I run the 455/55 on the drives and 445/50 on the trailer. They're okay on wet or dry road, but suck big time in the snow, I've had to lock differentals and power divider in four inches of fresh powder just to move. There is nothing more useless on a truck in the snow, except the non-directional military mud & snow tires from years ago.

 

The snow driving was what I was wondering about, Driving every week thru Michigan and up thru the snow belt, and across US 2 makes me wary

 

I ran into some bad weather last week up in northwestern Indiana and I was impressed, I didn't have any troubles, not yet anyway. We'll see what the rest of winter is like driving on them. Didn't know what to expect, this is my first winter driving on them.
