The cooper compound is softer, it’s not worse, just softer, this equates to quicker wear yes, but it also means a better tyre for wet, snow, ice and freezing conditions. The bfg’s I’ve had have been outright lethal in very wet conditions and on slippery and icy roads - they’re know for that due to their hard durable compound which gives them long life and puncture strength - it’s a trade off.
I know I will never put a set of KO2’s on my car when the heavy late summer rains and the snow/ice approches, recipe for disaster in my book.
I’m happy to trade in wear and lifespan for better grip and a tread pattern which actually clears itself of mud and snow and doesn’t hold on to every pebble I drive over!
This is what has attracted me to the Cooper ST Maxx
