I found a great budget sport touring tire that can be had for less than $200 US for both. I recently paid $177 shipped.
pits the Continental Conti Motion. I’m not sure if they make your size but they perform well and wear well.
In my experience, the Bridgestone Battlax bt and T series are best for mileage but these Conti Motions seem to be holding their own.

New tire installed.

As you know the midle was flat…. the front tire is not flat same way…. could it be I’m running on to low air pressure?

I use 2,5bar = 363 psi

As a rule pronounced centre wear = too hard and equal pronounced side wear = too soft although obviously with a bike if you do lot's of straight road mileage then centre wear would be normal and the rear would be greater as it's the "driven" wheel

Some motorcyclist  consider it a badge of honor to wear the sidewalls of both tires out before the center tread proving their corner carving  abilities

Indeed, keep them "chicken strips" lean

So long as you use 2.5bar and not 363psi. Might be a bit of a harsh ride with 363psi ;)

Generally speaking, high pressure will result in more wear on the centre of the tyre, and low pressure will result in more wear on the outer edges, especially for cars. But in reality it more comes down to your riding style, anyone who does a lot more highway riding than lots of twisties will wear out the centre first, that's just going to happen.

I'll also mention tyre width, but I don't think that's your problem. You can fit wider/thinner tyres to a point, but many people think 'wider tyres = more grip' and put 130 tyres on 100 rims (for example). What this does is squeeze the tyre in to fit the narrower rim, which will make the tread more 'pointy', which significantly changes handling, and can also result in less grip due to the point creating a thinner contact patch.

When I was in college, commuting by bike, during the KZ era, I burned through a lot of tires.  A friend was racing a GPz550 back then, and he would toss me his worn out (sidewall) tires, which I would then wear out in the center.  It was a perfect partnership!

I generally get 5000 milers a rear tire. I check/adjust the valves at that time.
