Discussion Overview

The discussion revolves around the implications of using different size wheels on an ATV, focusing on stability, performance, and the effects of wheel mass and moment of inertia. Participants explore theoretical and practical aspects of this topic, considering various vehicle types and conditions.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • Some participants suggest that the stability of an ATV is influenced by the center of mass in relation to the wheelbase, with larger wheels potentially raising the center of mass and lowering stability.
  • There is a consideration of the need to widen the wheelbase or add ballast to improve stability when using larger wheels.
  • One participant notes that using different size wheels can lead to varying angular accelerations, which may impact stability.
  • Another participant raises the question of how moment of inertia, which varies with wheel mass, affects stability.
  • A comparison is made to racecars, where different tire sizes are used for stability during high-speed turns, although this may lead to shorter tire lifespan.
  • One participant inquires about recommendations for wheel selection based on specific usage scenarios, such as rough terrain at lower speeds.

Areas of Agreement / Disagreement

Participants express differing views on the impact of wheel size on stability, with no consensus reached on the best practices or outcomes of using different size wheels on ATVs.

Contextual Notes

The discussion includes assumptions about vehicle design and intended use, as well as the potential effects of surface conditions on stability, which remain unresolved.

Can we use different size wheels in an ATV from stability point of view as they have different masses
 
Engineering news on Phys.org
Welcome to PF;
ATV means All Terrain Vehicle to me. Just checking.
Even so, there are a wide variety. Presumably we can rule out hovercraft ;)
Maybe tracked ATVs ... still leaves a great many with just wheels.
Do you mean things like the quad-bikes?

The stability depends on the location of the center-of-mass in relation to the wheelbase.
Larger wheels can raise the com - lowering stability. Imagine an extreme case - if you used truck wheels say?
You would want to also widen the wheelbase and/or add some ballast to improve stability.
 
But if we use different size wheel by chance then it also cause different angular acceleration of wheel that impact too during stablity
 
How so?
 
Because moment of inertia of the wheels are different as they have different masses
 
How does the moment of inertia affect stability?

It depends on what you want to do with the vehicle and what type of surface it will be running on. A racecar, say NASCAR for instance, may have 4 tires that are four different sizes and they do it for stability in a turn at 250 + KPH.

Then again the tires don't last long.
 
Likewise if I choose a rough traine at max 60kmpl then what you suggest to choose
