When I bought my car over 2 years ago ('10 GTI) it had tread cupping on the inside rear tires. I bought new ones, got an alignment, and new rear shocks (Bilstein B4). I've rotated the tires a couple times since then and they are showing the same cupping as before with about 30k on the tires. Is this a general problem on these cars?
I'm considering adjusting the alignment with less camber to see if it helps. Maybe -0.75/-1.00 instead of -1.3/-2.3.
People say it can also be due to bad shocks. I feel like mine should still be good after only 30k...
Another thing I was thinking about is wheel weight. Mine are the Detroits which are notoriously heavy for factory alloys, and I'm wondering if the OE shocks have a hard time dampening the weight, and thus causing excessive bounce even though the wheels/tires always balanced well...
I hate the fact that my tires are wearing out in less than two years. Tread depth is still ok at 5 and 6/32nds.
Here's my alignment readout.
