The tyres on my 250d don't grab or make horrible noises and I'm running Vredestein all seasons on 20" AMG wheels. They never did even from new and now the knuckle issue on mine has been sorted there is no clonk on full lock at low speed either, I've tried several times to get that and can't.
There is tyre noise certainly but no more than my previous BMW 2wd or 2 Audi Quatros and much depends on the road surfaces locally, some of ours are very rough and as in any car you definitely feel the potholes if you can't avoid them.
In general I find the GLC at least as quiet as the other cars I've had which all had leather so no upholstery sound deadening, I've suffered fro tinnitus for a long time now and the car doesn't affect me. I've owned the car for 26 months and driven 14,000 miles so enough to have an informed opinion.
As said you need to borrow one for a weekend and decide for yourself, it's all subjective.
