Mercedes-Benz files patent for tyre cooling system; can also be adapted for tyre warming in cold weather

Wet tyres typically spell less grip and pave the way for loss of control, but Mercedes-Benz has an idea: it has applied for a patent for a system which uses water spraying to control tyre temperatures.

Through monitoring of tyre temperatures, the system applies a cooling spray of water to the tyres should they exceed a pre-determined threshold. The idea behind it is to prevent tyres from overheating under hard use in hot weather, which could lead to tyre failure. “Increased driving safety is achieved as the bursting of tires can be prevented by applying the fluid to a tire which is overheated,” says the company’s patent application.

Conversely, the system could be employed in much colder climates; it can spray warm water on tyres to reduce the build-up of snow and ice, and to prevent under-inflation in cold weather. According to the patent, water can be heated from the vehicle’s coolant system for its cold climate application.

This system also employs sensors to detect rainfall that might cool the car’s tyres, and it also collects rainwater or melted snow from the windscreen and rear window to refill the reservoir for the temperature management system. So far, this idea is only at its patent application stage, so it remains to be seen if such a device will materialise and reach production.
