I've got some all season Kleber tyres with the 3 mountain peak snowflake symbol fitted to my van and a more perfect device to collect stones would be hard to come up with!
Do you have this issue with your tyre LightSpeed?
I don’t drive off road much but it picks up pebbles about the same rate as the oem tire. However, it does have way more traction.
If i did not have a tray in the boot it would be of more concern but since traction is what the goal is then i found it. It is more squishy because it is a soft rubber compound and if i was racing it would not be my first choice of tire.
