Correct air pressure for Crossroads Armadillo tires

I put on Crossroads Armadillo tires two weeks ago and I am having a hard time getting the tire pressure right. The recommended pressure is between 75 psi and 100 psi. At 80 psi, the tires feel very hard and the front tire does not feel stable when I turn. It feels like it is slipping. Any suggestions would be appreciated.

I ride a Giant Cypress and weigh about 173 pounds.

Thank you.

Some tires are more hard/rigid than others.

The slipping on the front is a concern. Many riders vary their pressures between the front and rear for handling and/or comfort. I would try running the front at 75 psi and see how that works for you.

EDIT: Especially on a comfort bike, the majority of your weight is on the rear, so among those who vary pressure, the pressure on the rear tire is kept higher to accommodate the greater load and reduce rolling resistance.

Correct pressure for any vehicle is based on the weight on the tire, and the size of the tire.
Only pay attention to the sidewall for the do-not-exceed rating.

Calculator: Bicycle tire pressure calculator

After using a scales to measure actual weight on each wheel, I run 28mm tires on my road bike at 100psi rear, and 60psi front. (I'm 185#).

You didn't specify tire size.
Any tire i've ran across with "Armadillo" in the name tends to be a heavy, hard, stiff, puncture resistant tire. Good for a lot of puncture resistant miles, but a real "slug" for handling, acceleration etc.

You may simply be better served with a different tire.
My 2008 Globe came with 35mm Armadillo Flak jackets. After a couple days I went to a 28mm tire and the difference was amazing. They just happened to be flat prone. I've since gone on to a 26mm tire 100/110 PSI. I currently weigh 240. I've been more than pleased with these. (folding)

I haven't used the 'dillo version,but I've used Crossroads before,and they're a heavy,kinda meh riding tire. Great for off-road and snow,so-so on regular streets. I think the stability issue may be do to the tread design;a tire with smoother tread may be a better choice.

I had the feeling this morning on my ride was that the tires were performing like they were supposed to given what they are. I am getting more used to how it feels when I turn. I just need to make sure I don't turn to sharply or go to fast. I also put both tires at 75 psi which felt fine. I rode for nearly 20 miles this morning without an issue.
