So the rules from the insurance company Stated that the tyres needed to be replaced with the same ones. Said repairers could not find a HT pattern in the original brand, so replaced it with ATs on the rear.
For whatever reason, as soon as the car was around 100kph, it was shaking like a blender.
Whether it was just the tyre type, alignment, balance, or whatever, the shaking stopped as soon as the tyres were replaced with HT ones.
Thanks all.
