Help with tire damage, patch or replace?

Driving home late at night, I noticed that one of my tires had slightly lower pressure than the others. I suspected a slow puncture but the car drove fine all the way home. I found some damage on my tires and I suspect the front left has a slow puncture, the front right looks damaged but I don't think it's punctured as the pressure has not dropped.

Front Left


Front Right


Can this damage be patched, or do I need to replace? I'm still on my original Conti EcoContact 6Q at about ~17000 miles but it looks like the front tread is already at 4/32 so maybe I'm due for a replacement soon. Rears still seem to have some life in them at 5-6/32

How close until wear bars even with tread?

They look pretty worn.

They are pretty close to the "Corner" which tires guys tend to get wishy washy on repairing.
Hard to patch a corner due to tire flex so it can come loose and leak real fast.

Plugs work too but I am only fan for slow movers, offroad stuff, lawn care vehicles etc...

But a car that can well over 100mph - Nah I would not get plugs

At 4/32, treat yourself and your car to new shoes.

Yea, no tire shop will patch that, it’s too close to the sidewall.

The fronts look to be about ~1/32 away from being even with the wear bars. It doesn't look like the front left has a slow puncture either, the tire didn't deflate overnight and the tire seemed to be holding pressure when I took it on a short grocery run. I'm suspecting that perhaps I lost pressure when the damage occurred but the Contiseal self sealing tech actually worked and prevented a full puncture.

I'm probably gonna replace them with the Michelin Pilot Sport All Seasons.

Let me share about a tire pressure loss on my side :

One of the rear tires (left rear to be exact) was losing pressure . I was inflating up to 23 kpa but in the morning it was dropping to 18 kpa but when I packed up miles , it could even go up to 20 kpa as the tire temperature escalated . Well, I was not convinced at all because why was it losing evening to morning ? I hit the tire shop and it picked up a nail . We found the evidence . It was patched and running fine .
Yours could be patched up too , I think, but replacing it is a better idea since those look worn out as well.
Anyway, good decision to replace it
Happy Driving
