It seems pretty plausible to me and is basically still a carry over from the TD. Tl:dr: They need to find a way to run the car at the intended ride and if they do (easier said than done) everything drops into place; if they don’t, it’s a compound effect (ie lack of downforce which makes the tyres slide, exacerbated the harder the tyres are given working window).
