Roadwheel

Right below me, passing us by, was a set of wheels that looked exactly like the roadwheels off a tank.

Check roadwheels and idler wheels for excessive heat, worn mounting holes, and separation of rubber from metal.

Handwheel is the preferred term for what is popularly called the steering wheel. The reason for this distinction is that a typical car has three steering wheels - two are roadwheels and the other is a handwheel.

Consequently, track segments between roadwheels cannot support much load and vehicle weight is primarily supported by the track segments (links) immediately under the roadwheels.
