Summer in ‘Straya the road surface temperatures can reach +60oC. Have you ever thought about what is happening to sealant inside a 25c road tubeless tyre rolling at these temps? Rolling at speed will spread 50ml of liquid inside the tyre to a depth of about 2-3mm round the tread. This thin film is constantly mixed, under pressure at over 50C. It does not remain stable for very long. Without very fresh sealant road tubeless riders should not rely on sealant inside tyre to protect against punctures. Need to carry a suitable repair kit including tyre plug and 60ml sealant bottle.
