Let me straighten this out.

There has been constant, long-standing confusion between the distinct meanings of “wheel”.

Wheel can refer to “wheel rim”. It is the cylindrical structure to which a pneumatic tire is attached. There must be one tire on each wheel rim and I am not aware of any exception.

Wheel can also refer to “wheel hub”. It is the structure to which wheel rim or wheel rims are attached with studs.Wmdoll 163cm Realistic Sex Doll with Large Breast Sexy Toys for Man. If the hub is on a driving axle,Custom High-Quality Shoes Women Men Sport Sneakers Graffiti Colorful Adults Casual Flats Lace-up Platform Running Shoes. On a steering axle, it is the hub that steers which in turn steers the wheel rim. There must be a pair of wheel hubs on one axle, but there can be one or two wheel rims on a wheel hub. Some agricultural tractors even have more than two wheel rims on one hub.

The word “wheel” sometimes refers to wheel rims, as in “18-wheeler”.

A tractor semi-trailer combination is a ubiquitous type of highway freight transportation vehicle all over the world. A tractor which has a “fifth wheel” pulls a semi-trailer,Candle with Tail LED Filament Light“fifth wheel” on the tractor is regarded as an articulation joint.

A typical North American combination consists of a tractor with three axles (one front axle and a set of driving tandem axle), and a semi-trailer with two axles. Before super-Fiberglass Cloth Reinforced Adhesive Tape Aluminium Foil Tape, all axles, except the front steering axle, are fitted with dual-tireson each side. That means two wheel rims, and hence two tires, on each wheel hub. Since one axle has two hubs, an axle with dual-tires counts a total of four tires.

So in the colloquial term “18-wheeler”, the word “wheel” here means “wheel rim”. An 18-wheeler has a total of (2+4+4)+(4+4)=18 wheel rims, and hence 18 tires.

However, an 18-wheeler has only 10 wheel hubs.

When does “wheel” refer to “wheel hub”?

When we refer to driving configurations, as in RWD, FWD, 4x4, etc.

If you ask any truck driver what his/her truck’s driving configuration is, he/High Performance Dry Fit Compression Gym Yoga Shorts

“It’s a 6x4” or “4x2” or “8x6”, etc.

A 6x4 means the truck has three axles, and two of them drive. Because, again, there are two wheel hubs on each axle, you times the axle number by 2 to get the wheel hub number.

But from 6x4, you will not know exactly how many wheel rims or tires the truck has. Most possibly, it has (2+4+4=) 10, but it could also be six (UV High Strength Flexible Fiberglass Reinforced Plastic Pole), or other much less possible layout.

So back to your question. Your statement is not wrong. It depends on how you interpret the word “wheel”.

Hope this clarifies things a little bit.
