Hi all, I have bought the last 2 years more tires: – Nexen Winguard Sport 2 – 2 of 4 heights – Hankook evo2 – 1 of 4 heights – Michelin Primacy 3 – 1 of 4 heights – Michelin Primacy 4 – 0 of 2 heights – Continental TS850 – 2 of 4 heights – Continental TS850 – 1 of 4 heights – Goodyear UltraGrip Performance + – 2 of 4 heights I wonder if I just had bad luck or if there are really so many tires bump problems. the tires B2B about a wholesaler who lists several dealers. What experiences have you made?
