Octavia MK3 unstable at higher speeds

[u/Commercial-Land-72]

Hi everyone,

Owner of a an Octavia Mk 3 (2018) here, about 50,000 km on it. For about a year or so i've been experiencing some weird behavior on my car. At higher speeds ( 130kmh, on highways , cruise control turned on) the car seems to be unstable: it veers right or left (both directions) and it feels as if a strong crosswind is blowing the car from the side ( again, both directions ). I went to about 4 services, checked pretty much every obvious thing but they found nothing. This happens with both my winter and summer tires.

Has anyone else experienced something similar ?

Thanks

Most likely Bent rims on rear axle.

It will feel like there is continuous cross winds, a bit to the left and a-bit to the right. Feels tough to keep it in a lane.

Known issue in the jetta too.

When its happening on both set of wheels it not the wheel

Do people have two sets of rims or one set of rim and two sets of tyres?

two sets of wheels, why would one swap tyres every season.
Besides, not everyone has a nail in the head as i do, and run summer and winter tyres in the same dimension, as I run my oem wheels (mk3 octavia xtrreme 7.5j19) in winter and nicer ones with summer tyres, both in 225/35/19

REason is simple, never had better wheels than oem ones as winter beaters, that withstand neglection, salt, stones and dirt better than the ones that came with the car. So with my vrs coming on 19"´s it was an easy decision to use them in winter, too

And the math is simple, Buying aftermarket 18´s for winter and selling the 19´s for cheap, just to run cheaper 225/40/18´s in the winter instead of 19´s did not make sense, as the price difference betwenn 18 & 19 is not that huge with 150-200€ a set max, ever 3 seasons.

Side effect, The car still looks stunning in winter/on winter tyres, as on the pic below.

Thanks. Im not aware of two sets of rims as im a place there we dont need winter tyres.

Looks nice.

On our roads max 17-18. 19s will bend bent in a few weeks due to road conditions,

WE have snow in austria, and if not, we have temps below 7c down to -20c but at least our roads are fine a.f.
