Had to change all 4 tires but not all same

I had to change all four tires as I got a flat and the shop found the tires were all shredded on the inside of the tires.

My original tires were michelin PSS 235/35/19

They only had 2 michelin PSS 235/35/19 available so they put them in the front (my car is FWD).

On the back 2, they told me they had Continental 245/40/19 and said it is fine to put them on the back
since my car is not AWD.

So the back tires are the same size (19 inch) but a little wider and a thicker sidewall. I'm guessing that would make the tires a little bit heavier than the front pair.

I didn't have any issues driving it a couple times between 80-120 km/h.

But just this morning I had driven at around 140 km/h and then I noticed some really strong vibrations
and pulled over to check it out. I didn't find anything unusual and continued driving at 80-100km/h and it felt fine again.

Do you think the strange vibration I was getting before was due to the tires ? Should I go back to the shop and ask them to fit the exact same 235/35/19s on my back tires and take off the 245/40/19s they put on?

I don't know if the mismatched tires are causing your vibration but if your old tires were all worn on the inside you need a 4 wheel alignment.

Sounds like the car has some alignment issues.

does that mean I can keep the different tires on but just do an alignment and everything should be fine
or get those back tires off, put on the same tires as the front?

If the vibration was only a one time advent it could have been the road. Over the years I've drove several vehicles where the front and back tires were different sizes with no issues. You definitely need to get an alignment.

What do you mean by "shredded on the inside"

Do you mean that the tire tread was worn on the inside (car side) of the tire.
OR
That the side wall was worn/shredded inside the tire itself.

Some sort of alignment issue and possible balance also. Vibration could of been road. but if continues I would get all 4 wheels re balanced.

All cars are designed with a certain series of tire. As long as the tires fall into the series of tire recommended then you're fine. However, it is not recommended to mix tires of different types even in the same series. It's done all the time and specifically for racing to get very specific performance. But it's not recommended for the average car.
But your main problem is alignment and balance.
