Driving a RWD LR. I'm not sure how to describe the noise, it sounds like some type of low grinding or traction control, but I hear it every so often on a drive, particularly when I'm first driving out of the neighbourhood. It doesn't matter if I come to a dead stop, hold, or rolling stop, when I hit the accelerator, sometimes there will be this grinding-ish that seems to be coming from the back wheels. It lasts about a second and then disappears. It happens on both turns and going forward, but always on acceleration. I'm not hard on the accelerator either. I feel like it's happened since changing to the winter rims (Replika R187) but it didn't have this issue last year. My wife thinks it began when the temperature started dipping, which was before we even switched to the winters. Any thoughts or anyone experienced this?
