GoClaws tire chains are injection molded out of a high-grade thermoplastic polyurethane. Designed for trucks, cars and more, the product is billed as easy to install and as working extremely well in snow, ice, mud or sand. In testing the product for 300+ miles on both dry and snow-covered pavement, the company says the chains showed little signs of wear. The company developed GoClaws as an alternative to conventional, noisy metal chains.
