Okay just got my tires changed.
At 10.5k highway miles my front tire had 4/32 depth remaining.
Rear tire had flattened out more than I realized and was down to 1/32 in the center after 8k highway miles.
The front tire I replaced with the stock michelin pilot steet. Back tire with the michelin power 2CT because the stock tires are backordered. Despite mismatch, bike feels good so far!
