Super Singles

I hear they are squirrely on wet pavement but I would never run them on a Class 8 or my RV.

Anybody running super singles on their class A???

For those of you unfamiliar with super singles they are a single WIDE tire/rim that replaces the duals on the rear axle(s) seen on some of the trucks on our highways.
The are very efficient BUT if you have a blowout your unable to limp to a station.

first i've heard of them. what's the advantage?

Very fuel efficient. My brother knows a guy that has 2 identical trucks, one has the super singles and has been getting MUCH better mileage than the truck with standard duals.

Good luck when you blow one of them on your coach. I have run them on the front of gravel and mixer trucks ans would never consider it on my coach. I ran them on steer axles and in slippery conditions they were terrible and on the rear I can't see them being much better.

I think your a tad confused Slickest1

You run them on drive axles, not steer axles as you just stated above!

Also clearly stated in my post above that you Can't limp down the road if you have a blowout. Not looking for any luck.

LOL

I have never seen a MH with super singles on it. I imagine that the cost of the rims and tires would take a lot of miles to pay back the gain in fuel economy.

With highway trucks, you can either order them with super singles or re-use the dullys on a different tractor (assuming you have a few tractors). I don't see a market for used MH wheels / tires.

Someone on here has them. There was a big discussion a few years back on them and one member tried them.

Mchero, you are the one confused. :S
Cement and trash trucks often use super singles on the front that are wider than the one used on a semi. Heck, many of the big DPs are using 365/80/22.5 on the steer and tag axles... I would call that a super single as they will carry more than the 17,000 lbs/axle allowed on a semi with tandem axles.

I found the old thread;

Super Singles Found Here

They were never designed for RV's and will not improve your MPG as they do on a class 8 truck.
