Just had 2 new falken ze-512's fitted to the rear of my astra, they replaced some Mitchelin Pilots.
Now, I experiencing what can only be described as 'squirm'. On fast roads (upwards of 50mph) I can turn and then, milliseconds later, feel the back end sort of flex and squirm.
When fitted they were inflated to 34psi - which I later corrected to 28psi - and it still did it with both pressures.
I can't swop them to the front, as the Nankangs there did the same when they were on the back - cured by swopping them to the front and having Mitchelins on the back, so can anyone suggest anything?
Has anyone experienced similar?
