Hello, dear Mitcaddyists, I have a question about the wear and tear of the tyres. My Caddy Maxi has been running since March 2008 with mileage 75000 km, I have DUNLOP SP SPORT 07 summer tyres 205/55 R 16 94H with max. load 670 kg. Front 5 and rear 6 mm. When changing in 2009, the VW workshop did not change the rear tyres forward. When changing in 2010, I now insisted on changing from rear to front. Now I have loud rolling noises of the former rear tyre, which now mounts in front. According to information from the workshop, frequent driving in empty condition builds up a bridge on the inside of the rear tyres, which leads to these loud rolling noises on the front axle. Can anyone confirm this from the forum? Do the tyres have to be changed from the rear to the front or do they always have to stay behind or in front? Would be nice if someone could write something to me.
