Tires for sale 165 ea in Burley idaho

What are the rubber to wire coefficients & carbon ratios in relation to the weight distribution and load transfer algorithms on these tires? Asking for a friend. Thx.

It's going to be pretty hard to gather from a picture. But basically I think what he's wanting to know is if the laboratory measurements of coefficients of friction of soft rubber compounds were made by towing specimens on horizontal tracks and by allowing them to slide down inclined tracks. The specimens are usually prepared by attaching the rubber to a metal backing and molding it against glass surfaces having different degrees of roughness. The coefficients increase markedly with speed, ranging from about 1 at 10- ' cm/sec to more than 4 at 5 cm/sec. The occurrence of vibrations prevented observations at higher speeds. Static friction is greater than dynamic friction for speeds appreciably less than 10- 3 cm/sec and less than dynamic friction for greater speeds. The coefficients decrease slightly with increasingpressures and are independent of the size of the specimen. Except atvery low speeds the smoother surfaces yield the higher coefficients. Materials such as talc or bloom on the sliding surfaces cause large decreases in the coefficients. Attention is called to the dependence of the coefficients of friction on the speed, which is shown in several previous investigations on rubber and other materials.

As far as carbon ratios in the rubber, it is the major constituent in the rubber compound used for the tread on the truck tires. A general compound formulation of the tire tread includes NR and BR as polymer base and carbon black as the reinforcing filler, and curative components. In this paper the effects of dual filler system (carbon black and precipitated silica) on the dynamic properties of tire treat has been studied. The results show by increasing of precipitated silica, significant improvement was observed in fatigue resistance, rolling resistance and heat buildup of the tire. Tensile strength and modulus and wet grip of tire tread decrease with increasing of silica in rubber compound formulation.

And in regards to load transfer algorithms, since cornering characteristics of a ground vehicle depend on lateral forces acting on tires, accurate tire models for calculating tire forces are required in vehicle dynamics controls. Over the past few decades, a great deal of research has been dedicated to the development of tire models [20], as a result of various tire models, such as Magic Formular, the Dugoff model and the Brush model, which have been proposed and applied to estimator and controller design. In this work, a linear tire model is used in estimator design for design simplicity. As shown below, the relation between lateral tire force and tire slip angle is almost a straight line when the tire slip angle is small, and can be expressed as follows:

Fyi = −Citan (αi)

So I think that is the data his friend will need. Again, hard to show in a picture.

^^^ yeah, that....thanks for clarifying man... I get lazy with my words sometimes.
