Hello everyone… I have recently bought a used BMW 316ti compact. Unfortunately, I only had to find out later that the Dunlop Winter Sport 3D tyres are attached to the car instead of annual tyres (as I would have expected, since the dealer told me that it would be annual tyres). Are the tyres now suitable for the summer also or should I rather switch to summer tyres? Because 4 of them already cost me 500ers in about. Does it mean wear and tear if I continue to use it in the summer? so I usually only drive in urban traffic with moderate driving. Thanks in advance!
