On a hot day, the interior of a parked car can become unbearably hot in just minutes—especially under direct sunlight. In fact, temperatures inside the vehicle can easily soar past 80°C, turning the cabin into an oven. This extreme heat affects many components, particularly the steering wheel and any attached accessories like a steering knob. For drivers, this raises concerns about usability and safety. At Okjaws, we understand the importance of reliability under harsh conditions. That’s why our steering knobs are engineered to perform smoothly—even after hours of sun exposure—ensuring drivers experience both comfort and control no matter how hot it gets.
When a vehicle is parked in direct sunlight with the windows closed, the internal temperature can rise drastically within a short time. This phenomenon, known as the greenhouse effect, traps heat inside the car. Even on moderately warm days, the cabin can reach temperatures above 80°C, creating an extremely hot environment.
Prolonged exposure to such high temperatures can damage materials commonly found in car interiors. Plastic parts may soften or warp, while rubber elements risk becoming brittle, sticky, or cracked. These changes affect both the appearance and the functionality of essential interior features.
For drivers, overheated car accessories aren’t just uncomfortable—they can be dangerous. A steering knob that warps, cracks, or becomes sticky can impair control while driving. That’s why heat resistance and durability are major concerns when selecting steering accessories, especially for those who live in hot climates or park outdoors regularly.
Okjaws steering knobs are constructed using a solid zinc alloy base, which offers excellent heat resistance and structural strength. The grip is made of high-temperature-resistant plastic, chosen to endure long exposure to sunlight without becoming sticky, cracked, or deformed. These materials are carefully selected to ensure both safety and comfort in real-world driving conditions.
Our products don’t just rely on theory—we back them up with rigorous testing. Okjaws knobs are placed in vehicles and exposed to direct sunlight to simulate real summer conditions. This process helps us confirm that the knobs maintain their appearance, functionality, and durability even after prolonged heat exposure.
The result of our careful material selection and testing is clear: Even after prolonged sun exposure, the knob remains structurally stable and safe to use. It retains its smooth rotation and comfortable grip, offering drivers full control without any compromise—no matter how hot it gets inside the vehicle.
Before getting behind the wheel, open the doors or windows to let the trapped heat escape. If available, turn on the air conditioning to cool the cabin quickly. This not only improves comfort but also ensures that any heated surfaces, including the steering knob, start to cool down before use.
If the knob has been sitting under direct sunlight, give it a gentle tap or touch to check the temperature. Thanks to its heat-resistant design, the surface is unlikely to be uncomfortably hot—but it’s always good to confirm before gripping it fully.
Even after sun exposure, Okjaws steering knobs function exactly as they should. The knob rotates smoothly, with no signs of heat warping, stickiness, or discomfort. The high-quality materials ensure a steady and controlled steering experience in all temperatures.
To reduce overall heat inside your vehicle, consider using a sunshade, tinted windows, or parking in the shade when possible. These small actions can help protect not just your steering knob but your entire interior from sun damage.
At Okjaws, we don’t just design our steering knobs in a lab—we test them in real vehicles under the harshest summer conditions. Our products are placed in cars parked under direct sunlight for extended periods, simulating what drivers face daily in hot climates. This allows us to observe how the materials respond to temperatures exceeding 80°C, ensuring no deformation, surface damage, or decline in usability.
Our internal testing results consistently confirm that the knobs maintain a smooth, stable performance even after days of extreme heat exposure. Many customers in tropical and desert regions have also shared their positive experiences, noting that their Okjaws knobs remain reliable, comfortable to use, and visually intact even during peak summer.
Whether it’s a commuter car in a humid city or a utility vehicle working under the desert sun, Okjaws knobs are built to last. Drivers can count on consistent functionality and comfort—no matter where they are or how hot it gets.
When it comes to driving comfort and control, even the smallest accessory makes a big difference—especially under extreme conditions. Okjaws steering knobs are purpose-built to endure intense summer heat, maintaining their smooth rotation, structural integrity, and safety even after hours inside a sun-baked vehicle.
Backed by real-world testing and trusted by drivers worldwide, our knobs offer the reliability you need in any climate. Choose Okjaws for a steering knob that won’t let you down—no matter how high the temperature rises. Because quality shouldn’t melt under pressure.
