I could feel the heat coming off it when I stood next to the repaved section. They didn’t repave the parking area at the edge. Opened to traffic again, seems firm enough to drive on at 160⁰F.

    Even though this article says that tire rubber starts to break down and melt between 100⁰C to 150⁰C, depending on the rubber compound, I’d still prefer to protect my tires from such high temperatures…

    Edit: Those temperatures are also rather dangerous for electric vehicle batteries, which are located right under the vehicle in very close proximity to the road heat.

            It’s not, many EVs intentionally heat up to over 50°C during fast charging. They also have several layers of material between the bottom of the battery and the road along with airflow across the entire area, so radiant heat isn’t going to have a meaningful impact.

                Acceptable range: 0°C to 45°C (32°F to 113°F). Below 10°C, the charging rate may be limited. It is recommended to charge the battery at 0~10°C and 0.2C rate. Above 45°C, there is a risk of battery charging.

                Eh?

                Above 45°C, there is a risk of battery charging.

                ???

                  Above 45⁰ Celsius, there’s a high risk of lithium ion thermal runaway (aka EV explosion).

                  Also, temperatures as little as anything above 37⁰ Celsius are known to cause infertility in men.

                    Did you even read the link you sent us?

                    Max 60°C: Continuous high temperature use will accelerate battery aging and capacity decay. If the temperature exceeds 70°C, the risk of thermal runaway will increase dramatically.
