Question about steering wheel

[Graymist]

I've been looking at quite a few trucks on Truckpaper, and have noticed that they have rather large steering wheels. Is it possible to have the steering wheel replaced with a smaller, more ergonomic one ? How much would it likely cost, and what type is the most comfortable ?

I thought the same thing until I drove for a while and love the big wheel. I have a feeling there is a law about how small they can be. A smaller wheel would allow you to make much larger corrections fast and that would not be good in a big truck. That's why suicide knobs are illegal.

what is a suicide knob? Never heard of that before.

One of those knobs you can attach to the steering wheel so you can turn it with one hand.

If you ever experience a power steering failure the large wheel will give you enough leverage to steer the truck to safety and park it.

With a small wheel, you'd be screwed!!!
