18 wheelers?

[orezok]

Now that many trucking companies are going to super single tires, only 10 wheels, what do you call them?

Big trucks, Semis, class 8....??? And what do they call them in Michigan, 32 wheelers?

My bro is an owner/operator, based in SoCal, and he has super singles all
around. He attributes them to helping him get as much as 9MPG on
some runs.

I guess that "big rig" is a common name here in CA, but I am used
to calling them 18-wheelers. I guess I should try to say, "semi".
"10-wheelers" are 3-axle dump trucks here.

The company I work for has super singles on all 32 of the sleepers. I think they are all Michelin 455/55R22.5. I was told that when you have dual wheels you will get less mpg because of the way the wind behaves between the tires. A disadvantage in super singles is getting a flat. Most likely you will destroy the wheel.

Yep, and none of the local tire stores around here keep them in stock. So, if you have a flat on a super single, you'll be sitting on the side of the road for a while.

And, I wouldn't worry too much about what to call them. My dump trailer is a triple axle, but I don't call it a 20-wheeler.

I've often heard "class 8" but never have heard any smaller trucks called by a "class..." number. I had to look it up.

The super singles have been around for a while now and are becoming more popular.

Less rotational weight = more mpg

Less rotational weight = more mpg

Everyone around here is running them now. Big advantage is also the tire tax. Its per tire so it adds up. I have been told that by the second set you have paid for the new wheels.
