What causes tires to blow out on TAKE OFF?
I can see some extra stress on landing.................
Trash on the runway.....................
they start to spin real fast sometimes bad tires go boom
The aircraft is much heavier on takeoff than on landing. Fuel.

The plane normally has a LOT more fuel on departure. One blowout puts more load on its mate.
Worn out tires, FOD.
Low tire pressure.
Causes?
1) Chord showing, ( tire thread worn away to the chord plies),per FAA, airlines can defer the tire change for 5 flights, which most do. A huge savings over time.
2) Low tire pressure, they are filled with nitrogen ( 250 psi plus from memory) from specialized equipment. Airlines have dropped Maintenance crews from many out stations, contracting outside mechanics for “ on call “ maintenance. Most of these stations do not have the nitrogen bottles, carts, jacks, etc.
3) Taxiing on an under inflated tire. It severely weakens the tire. If taxied on an under inflated just once, the tire is to be replaced.
This all points to a Maintenance issue. The FAA will most likely force the offending airline to instate a costly tire maintenance management program. All mechanics will have to sign off the “ read and sign” bulletin, take a few CBT’s on tire inflation basics, do special daily tire inspections, and submit to more FAA ramp inspections.
The bigger question? If tire inspections are not being complied with, then brake inspections probably are not. Most brake assemblies have indicator “ pins”, >1/8th inch showing is the norm. A tire failure pales to a worn brake failure, the burning magnesium is hot, very hot, and very difficult to extinguish.
More fuel, heavier, noted above.
Takeoff speed higher that landing speed, although aircraft wasn’t at takeoff speed yet.
Tires with “reinforced tread” (two layers of cord) can remain in use with the first layer of cord showing.
Did see a tire with a chunk of tread missing clean down to the fabric. Yeah we changed it.
This is military experience with heavy transports, and 45 years ago.
The most stress on aircraft tires is during ground turning
