On your first picture I see very little squish out, and you said that is only 30... not even the door sticker 32 (every vehicle I have is 32, so I kinda assume yours is too).... How confident are you in your tire gauge? and just one gauge? I think we all know that excessive wear in the center is overinflated... but that doesn't explain weird wear pattern. If you have a couple different gauges check em against each other. My first guess would be sun rot + overinflated. Kinda a stretch to just say that though, do you always park so the front are exposed to morning or evening sun and the rear are shaded?
You have a lot of meat left on the tire , especially for 8 years old... so much so I am kinda wow'd at how few miles you put on. Discount Tire here in Colorado will not repair, rotate, or even let you back on the road with anything older than 6 years. "Any tire over 6 years old is aged out and too dangerous for the road" according to them. My 48 (which is garaged) has no sun rot and is easily 15 year old tires. 6 years is ridiculously low to me, but on a vehicle that never gets relief from the sun I can see the new compounds getting brittle and starting to chunk out/fail early.
Parking consistently every time with that wheel cant as shown in the first pic, I can see how the driver's front would be getting all the sun in the world. Is there a big difference between passenger and driver front?
All 4 the same brand? My GM vehicle had michelins from the factory and I had a tire fail from "internal separation" the tire shop said, they replaced all 4 because it was a known bad batch. 2 more (michelin's) failed (less than 5k) and I went to a different tire shop and got a different brand. 5k miles later my last 2 michelins looked terrible - not like yours, but illustrates brand X sometimes just wear and look like almost crap right away.
As long as we are going there - are all 4 the same week/year or close? I have gotten a set of 4 "new" tires and 3 were made 2 months ago, one had been on the shelf for 2 years - oddball size.
One other thought for a road truck that doesn't see offroad... do you drive on a lot of macadam, or especially new macadam. (road made of crushed rock pressed into a tar substrate) Combine well aged tires, sun rot, and macadam roads the front (cause of the weight on the front) would be first to show the damage.
