2008 Passat 45k. No accidents. Towed twice on flatbeds due to bad fuel pump. Tires were rotated every 10k or so.
I’m wondering if there are any suspension (or wheel) issues that can lead to maybe tire wear and a loud oscillating noise. I had factory Goodyear Eagles 235/45-R17’s that started to develop a very loud speed-dependent oscillating noise that definitely came from the tires, but I can’t tell if it’s one tire or more than one. I just had them replaced though I was not quite yet down to the wear indicators. My new Continentals are of course pretty quiet, but occasionally I think I hear very faint oscillations again on certain surfaces at high speed. I’m worried that I might trash these new tires. I had to have an alignment/balance/rotation at about 30k due to minor steering vibrations at highway speeds. The noise started around 37k and got louder and louder. About this same time I had a flat tire that was immediately repaired; I noticed uneven wear on this flat tire which I attributed to the previous minor alignment/balance problem. I usually find out about any low pressures by the dash light, so I’m pretty sure my tire pressures are usually good. I rotated at 40k with a minor improvement that got bad again after about 1k.
