I don’t have a Formentor, but I found the same with the Turanzas VW fitted to my 2020 Polo GTI+ from the factory when it was new. I’m in the UK and based on forum member feedback on a VW forum, other UK owners of the same make / model of car on 18” alloys also had Turanzas on their cars, so it seems this was VW’s tyre of choice at the time.I don’t find it irrational for tyre reviews to have entirely different outcomes, because they are conducted on different cars, outside temperatures and road conditions, which can make a huge difference.
The reviews that really matter, are the ones on your specific car. I don’t care what any reviewer says. I am driving the darn thing and I can tell for sure that on the Formentor the Turanzas have underwhelming grip and road feedback and they hop like crazy when i apply too much throttle.
Like you, I too found I experienced wheel hop and tramping; happened fairly regularly when pulling away on virtually dry roads in UK autumn temperatures. And that’s with applying very little throttle as I’m quite a sedate driver these days (mature, retired). I put up with them for just under three months and then got some Michelin PS4 tyres fitted and haven’t had any issues since.
It’s interesting that VW are now fitting performance rather than touring tyres to UK spec Polo GTI’s with 18” alloys; Continental Sport Contact rather than Bridgestone Turanzas.
