Loopwheels come in front- and rear-specific versions, one of the key differences being that the springs in the front wheel are twice as compliant as those in the back. This is (presumably) to help keep the wheel that does the steering from being knocked and bounced around, plus it compensates for the fact that more of the rider’s weight tends to be centered over the rear wheel.

Things turn even further in the favor of the ASW system if you factor in punctures, blowouts, tire fires and how long a truck has to be out of service each year while those monster tires get changed. ASW treads are bolt-on, bolt-off chunks that can be changed with very little gear, without even jacking any wheels up, and done in sections during shift changes and lunch breaks so the truck's never out of service due to tires. They can also ship much more cheaply, since the whole assembly can be broken down into bits that easily fit in a regular shipping container.
Another obvious choice for marked visual and performance improvement is an upgraded set of wheels. Project e-tron came from the factory with the largest possible 21-inch wheels that were light, forged and optimized for e-tron – narrow width and rated for the higher weight of electric batteries.

Studies have shown that wheelchair users are exposed to levels of vibration that are considered unsafe and that this can affect health and life quality.
The three loops in each wheel work together as a self-correcting system. This spring system between the hub and the rim of the wheel provides suspension that constantly adjusts to uneven terrain – cushioning the rider from bumps and potholes in the road. In effect, the hub floats within the rim, adjusting constantly as shocks from an uneven road hit the rim of the wheel.

Cases to consider: 1: Idle - the spring should be able to carry the rider with no deflection, other wise if u lowered the spring from the beginning making the ground to hub distance smaller than the horizontal radius, you might experience lifting. but if it can support i believe its good
