I purchased 4 Goodyear 2 Asymetrric2 weeks ago. Up till now, I can't seem to eliminate a slight lumpy feeling which can be felt. I can feel the same through the steering too.I took the matter to the shop and got it balanced again for the back and twice for the front tyres. They claimed it is not the tyres or the balancing.I had Goodyear Asymetrric original before and had it balanced nearly 4 or 5 times using it. I later switch to Michelin PS 3 and now to Goodyear 2 Asymetrric with some regrets.Of all the tyres, I never had any lumpy feelings or shakiness or problems with PS 3 or even with my very old PP2! Is Michelin better made now? Are others having problems like me on their car?
