Different Tire Characteristics
I bet you didn’t know new & used tires had so many characteristics, did you? In this article, we’ll cover some of them so that way if you ever get stuck in a conversation where they’re talking about used tires wheels or something, you’ll know what you’re talking about.
The Contact Patch
The contact patch of used tires is also called the footprint. It’s the area of the tires that makes the most contact with the surface of the road. This is the area of your 16″ Used Tires that transfers forces between the tire and the road via friction. There’s something called a “length-to-width” ratio of the contact patch that will actually affect the steering and cornering behavior.
I hope we all know what tread is .. I’m sure we can all point out the tread on new & used tires that we get from random Used Tire Shops .. right? When you have poor wheel alignment, this can eventually cause excessive wear of the innermost or outermost ribs. If you go over a lot of gravel roads, different rocky terrains, and other rough roads, this will also make the tread wear out faster than usual.
When your tires are over – inflated, this will eventually lead to excessive wear to the center part of the tread. If your tires are under – inflated, the outer ribs will experience most of the tread wear.
Dry traction is usually measured by examining the tire’s ability to deliver either traction or grip under dry conditions – like when it’s really hot outside. Dry traction is considered to be a function of the tackiness of the rubber compound.
This is measured by the tire’s ability to give the driver traction under different wet conditions. The wet traction of new & usedtires is usually improved by how well the tread design is. If the water can be channeled out of the tire with no hesitation, then you have less of a chance of hydroplaning.
Both the tire tread and the sidewall elements will usually undergo different kinds of deformation and recovery as they enter and leave the footprint. Since the rubber on used tires wheels is considered to be elastomeric, it’s usually compressed during this specific cycle. When the rubber deforms and eventually recovers, it then conveys cyclical forces into the vehicle.
These variations are often known as Tire Uniformity. Tire Uniformity is usually characterized by Radial Force Variation (RFV), Lateral Force Variation (LFV), and Tangential Force Variation.
When you go to get your used tires wheels rotated, it will automatically release some sort of centrifugal force characteristic of its center of gravity. This is the force that’s referred to as balance. When it’s a nonuniform force, it’s referred to as either imbalance or unbalance. New & used tires are always checked at the same point of manufacture for both excessive static imbalance and dynamic imbalance using automatic Tire Balance Machines.
After this, the tires are checked one more time in either the auto assembly plant or the Used Tire Shops after they mount the tire onto the wheels. In order to speed up the routine of balancing, there are some high performance tire manufacturers that place red and yellow marks on the sidewalls to permit the best possible match-mounting of the tire/wheel assembly.
Hopefully this helped.
