They should be replaced immediately. The nexen tires are crap.

At my 35K (mi) scheduled maintenance, I was told I had 2/32 left on the OEM Nexens.
I started sliding sideways when taking off from the lights in the rain. The very next opportunity I had Pilot Sport 4 on and never looked back.
I've used Nexen from South Korea and found it very decent compared to Chinese ones which can be noisy.
Nexen tires are massively better in quality and value. I trust Nexen not only with my life, but put them on two of my kids vehicles when they went away to college in the Dakotas (extreme climate variation and brutal winters). Right now we have three vehicles on Nexen tires. In general, Nexen tires are not only worth the money, but they give more value for the price than most tires... They are not the "best" tire out there, but they are a good, quality tire that punches way above their price point.
I had the Nexen Winguard Sport (not the 2) on my 2019 Mustang GT. I drove that car (RWD, manual, 460 hp) for 3 winters on those tires and never had any problems.
IMO those tires were bottom of the barrel. I would just replace.
We use Nexen Winguard Sport 2 on our Focus RS AWD... they work very well... they are good tires and punch well above their price level in terms of performance and longevity.
I whole-heartedly recommend the Nexen N5000 Platinums... They are not the best tires out there by any means, but punch way above their price category in quality.
I have these, from Sams Club - using on a 07' Saab 9-3. No complaints.
