The tyres on my Mercedes-Benz GLC 250d keeps crabbing. It's on Pirelli 20-inch run flats and I live in Australia. The issue is the low speed right hand turn on a roundabout with camber. Left front tyre feathering on outer edge. I finally got 4 wheel alignment done, all out. Much better after that done. Rotating tyres at 10,000km to even out wear. Crabbing minor now on same intersection, done 21,000km, had work done at 9000km.
