Tyre sidewall splits

[kevino47]

I have a Specialized Rockhopper with Maxxis High Roller 26x2.35 tyres. I've only just noticed lots of short diagonal splits (almost like knife nicks) on the rear tyre. They seem to be in line wth constructional lines within the tyre. I know I've done some riding with the tyre slightly under-inflated but is there any connection ?. Has anyone experienced similar wear and do you think its safe to ride on ?..Many thanks for any replies

I've had Hookworms get little cracks that follow the sidewall, not radially across it.

If it's actually split then the most likely cause is dried out rubber in combo with low tire pressure. Long term storage in direct sunlight or close to a source of ozone (electrical machinery) can cause the rubber to become brittle. Unless bulging probably OK to ride on.

Watch it frequently; the little slits turn into big flaps with the inner tube showing through rather quickly.

Thanks for all your replies folks. I'm still going out on it and obviously, I'll keep an eye on how it develops and keep you posted
