The issues were immediately and since then I’ve done about 10k on them.
i then had the wheels realigned which marginally improved the situation.
then i went to a Lexus specialist who found nothing wrong with the tires nor the ditting, and did another wheel realignment and calibrated the steering wheel, which further improved the situation.
but what remains is that the tires are not stable in a straight line and you always have to be alert that it starts drifting, usually to the right (our roads are lower on the right hand side) and it’s worse at higher speeds. But sometimes all is well so i think the tire is just very sensitive. I read somewhere that the tire surface, veinf slightly concave with no central grooves give it worse straight line stability, especially on a tear wheel drive car.
i find this web page which is a perfect fit to to my issues, which is who I’m considering replacement.
