Sometimes you just gotta live on the edgeI would replace on my bike but they are fine on yours - its not like it rains hard everyday so chances of loosing traction this week is very slim. Also try riding aggressively - if your tire isn't loosing its footing, try going faster. I'd wait until you lay her down at high speed or have the rubber so worn that you can see the steel strands. Then and only then should you replace that tire. Safety is over rated
Thanks for the reasoned, thoughtful response. I think the amount of tread we want on our tires is a matter of personal opinion if we are not running the tire down to the cords. I also think your actual tread depth standard is very useful to help answer the OP's question.Most wear bars are at 2/32nd. IMO, the tire is unsafe in the wet long before that.
I typically replace at 4/32nds or before any trip where the mileage I expect on that trip will get the tire to under 4/32nds before I return.
That is my rule for a touring bike or any bike I'm going to take on a trip or significant distance. Now...for an in town only errand running bike like my Grom, I may take down to the wear bars as I won't likely ride in the wet on that bike.
Bottom line...I don't ever want to be riding in the rain on a tire with less than 4/32nds.
The tire in the first pic looks like it has 6/32nds or more to me. Maybe it's just the way the picture looks but new tires only have 7 or 8 / 32nds so a tire with 6/32nds is still good to go for me.

I confess to being a bit stupid here. I once ended up nearly dumping my Wing because I did not pay attention to the fact that my rear E3 was down to the cords and had an issue on wet pavement. I also ended up 1000 miles from home with a bald front tire when I could have easily changed it before I left on the trip. I was just last week considering going on a 3500 mile trip with a front E4 with 3/32s of tread remaining but I dodged that bullet and am replacing the tire the week before I leave. Some of us can be taught, we are just really slow. :frown2:
Ohh......Now that hurt!!!:crying:
