Modern tires, a crucial part of any wheel assembly, are made from over 200 different raw materials and chemical compounds. Unpacking the complete list of ingredients in wheels reveals a fascinating combination of metallurgical and chemical engineering that influences vehicle performance, safety, and cost.

According to material scientists, Ultra-High Molecular Weight Polyethylene (UHMWPE) fiber is considered the strongest by tensile strength-to-weight ratio, surpassing even steel. While many contenders exist, including natural and synthetic types, UHMWPE brands like Dyneema and Spectra consistently outperform most alternatives for ultimate tensile strength. This article delves into the science behind fiber strength, comparing the most robust materials available today.

Fifteen times stronger than steel on a weight-for-weight basis, Dyneema® (a brand of UHMWPE) is widely considered to be among the strongest fibers in the world. The reality, however, is that the title of "strongest" depends on the specific metric used and whether you are comparing natural or synthetic materials. For many applications, a fiber's specific strength—its strength-to-weight ratio—is a far more important metric than its absolute tensile strength.
