Multi-tiered quesiton: tire wear and spaces

[Wild one]

You don't need to measure. Wild is spot on. You can easily see it in the footwells. The reason the right tire spins on an open diff is that right side axle is just slightly longer and puts more torque to that side.

Notice how the diff is not in the centre, which accounts for the longer axle. You can also see the engine offset.

You're close,but it's actually the twisting motion of the driveshaft that lifts the passenger side of the diff Dean. The longer axle would actually apply less torque to the wheel,but the engines torque actually lifts that side of the diff,causing the passenger side tire to actually have less weight on it

Wild, have to disagree with you. A longer axle creates more torque. Torque is force over disatnce. The longer the lever the more the torque.

Think of a 1/2 inch drive ratchet. The ratchet with the 18" handle applies a lot mor torque to a bolt than a 1/2 drive with a 6" handle. Thus the reason we often add a 2 foot pipe to a breaker bar to crack loose stuck nuts.

The lift caused by the rotational force may also play a role and I had not considered that.


Torque Formula

Torque is the product of force and distance of the point of application of force and the axis of rotation.
Torque (τ)=Distance (r)×Force (F)=>τ=r×F

Because it is a product of some distance and a physical entity like force, torque is also called moment of force. r is called the length of the moment arm or lever arm. Also, since the rotating object describes a circle, r is the radius. Notice that the longer the lever arm, the higher the torque.

As mentioned before, torque is a vector quantity. Therefore, in vectorial notation, torque is given by
→τ=→r×→F

Using the right-hand rule, we can find the direction of the torque vector. If we put our fingers in the direction of →r, and curl them to the direction of →F, then the thumb points in the direction of the torque vector →τ.

It's a good theory,but doesn't apply to an axle Dean.I'm guessing you know a longer socket extension reduces the torque applied to the socket,same theory applies to an axle,the longer the axle,the less torque applied to the wheel.You're also not factoring in axle twist,the longer an axle the more it'll twist,which also reduces the torque applied to the wheel. The rearend lifts on the passenger side from the rotational forces in the driveline,same way an engine rocks to the passenger side when you floor it ,even in neautral if you floor the skinny pedal the engine rocks to the passenger side from rotational forces. Normally i agree with you,but on this theory you're not quite on the mark,lol. You're using a lever as the basis of your idea,and the axle isn't a lever,it's strictly an extension of the spider gears,and it doesn't increase torque,it reduces torque

• Torsional Wind-up: A longer axle has a greater ability to twist slightly under heavy loads. This acts like a mild torsion bar, which can momentarily absorb shock but does not increase maximum torque.
• Stress and Leverage: A longer axle creates a longer lever arm for the wheel to push against the axle housing and bearings. This puts more stress on the axle components and bearings, but does not multiply rotational torque. [1]

You're not thinking through what it means by the axis of rotation. Does a longer screwdriver give you a torque advantage over a shorter one? The breaker bar works due to it's moving the force applied a further distance from the axis of rotation. The screwdriver, regardless of length, is the same distance from the axis of rotation, it's parallel to the direction the force is moving. Same for an axle shaft.

Yep, Doc and Wild, now that I think it through both you guys are right. The screwdriver example is a perfect way of looking at it. Sorry if I caused any confusion but you guys cleared it up well. Thanks.
