i have replaced them at 80k and found them to be not in the least worn out. but it all depends on driving conditions they have been subjected to.

the first thing to go is ride quality. when the car starts feeling bouncy they are tired.

this will happen before any leaking or unsafe handling becomes apparent. so how is your benz riding? if it feels like a benz should, probably they are not worn out yet.
