No tire made is to run below 26psi. No tire is designed for that. And agreed your tire pressures are a bit too low. It's ok to drop a little pressure, since the manufacturer's numbers are usually for two up riders with extra stuff. For solo riding dropping pressure 25%, to what is then 75% of the max pressures is about the most you'd drop. Dropping too much in the front will alter the feel and steering. Under-steer feeling, it will push out. And that 26psi minimum thing, the front doesn't like getting close to that. And the pressures on the tire sidewall are not the pressures for your bike. The pressures shown on the bike or in the manual are the ones I'm talking about. If you're using the stock size tires. And yeah, you're getting a lot of miles from the tires. And also agree stick with a dual compound in at least the rear, that you like. That will help limit the flat spotting. Although it's a motorcycle tire, it wants to flat spot constantly.
