Maybe running at low pressure? This isn’t unusual wear for two year old tires

Looks like low pressure and the bike is stored outside often. UV damages tires very fast. The cracks look like UV damage, the sides also affected by pressure.

Have they been stored in the sun? The rest of the tire looks all dried and cracked too.

Check to see if the arms of the brake caliper rub on the side of the tires when the brakes are actuated

Look like Continental road tyres that are too narrow for the wheels?

You mentioned using 95 PSI, which is absolutely normal so pressure has nothing to do with this.
I think it could be just environmental thing combined with high mileage. The tread also has a lot of those small microcracks. I think these tires have seen more than 5000 miles?

Are you running larger width tires than came on the bike? Is your brake caliper rubbing against them when you brake?

Those tires look really old. Tons of dry rot on them. Conti automotive tires do this a lot too. Assuming you ride a lot, two years is a long time even if you store them in doors. I get about a year out of my gp5k’s before they start doing this. But never had it so bad on the side wall. Just get some new tires and assume they will do this again if you stay with Contis.

Lots of weathering here, makes me think it’s been exposed to the sun for long periods of time.
