I get 5/8k on the main commute bike, out of the Big Apples, though have had
two rear tyres retired early due to sidewall damage, they have always
reached a point of death by a thousand cuts than wear out.

MTB bit over 1k for tyres before they are toast, soft compounds so that’s
about what one would expect really.

Gravel bike 3k front 2k rear give or take, gravel tyres tend to the fast
and fragile end of things so do occasionally get dramatic failures or at
least tyres that might get me home but no further!

The roadie commuter I’d expect 2k ish but it does low miles so let’s see.
