Micro cracking on Tyres?

[davo245]

I have had this issue on Goodyears and Dunlops recently, the goodyears were only 18 months old when they started showing signs of cracks down the middle of the main water channels (largely shielded from UV light)

I am told it is down to modern rubber compounds and a lot of high performance tyres suffer from it.

The Pzero on our GTI seem fine though and they are 4 years old.

Wonder if it could be caused by certain wheel or tyre cleaning products or tyre dressings?

Happened to me way back. I incorrectly mixed a cleaning product I used for the wheels. Tyres ended up scrap. I still use it, correctly mixed and no issues since. Tyres were Goodyear Assy's.

Apc or bilberry etc?
