Personally I've not been eating up my tires 'at an alarming rate'.
I had 2 sets of tires; summer tires as they came with the car when it was new 8 years ago and winter tires 1 year after.

I still have them, after 165,000 kilometer, but I just swapped the old winter tires for a set of hardly used winter tires.
I keep the old set (about 85,000 km on those) as it still has enough profile to use at the rear of to be used as spares, if ever I need one.
My summer tires (with about 80,000 km) are still going strong. I'll probably change them next year, or the year after.

I have never been able to get that many miles from one set of tires before.
But then, I never ran as much pressure as I do now before.

The effect of higher tire pressure on rolling resistance makes itself immediately clear once you let your car coast from a set speed, like when approaching a red traffic light.
At first I had to brake more than I liked, still used to release the go pedal at the same point as I did before.

So there you have it.
High pressure makes your tires last longer rather than shorter.
This is because the notches in the thread hit the tarmac at a lesser angle, therefore scrape less when they get pressed flat in the contact patch, and because the whole tire flexes less and deforms less in corners.

It pays to have top quality tires. Especially because you'll enjoy them for longer than you would on lowish pressure.

Check your medication dosage amount.
