Road chemicals, cleaning products, and environmental substances can degrade tire rubber over time—prevention is key to protection. Road salt (used in winter) and deicers corrode rubber, causing cracking and dry rot. Rinse tires thoroughly after driving on salted roads to remove residue. Avoid using harsh cleaning products (e.g., bleach, ammonia) on tires—they strip protective rubber layers. Opt for pH-neutral, tire-specific cleaners instead. Petroleum-based products (e.g., some degreasers, lubricants) soften rubber, making it prone to tears and premature wear—keep these away from tires. When parking, avoid contact with concrete sealants, oil spills, or industrial chemicals, which can damage rubber. Apply a water-based tire protectant regularly to create a barrier against chemicals and UV rays. By shielding tires from harmful substances, you preserve rubber integrity and extend lifespan.
