If u take my word, Good Year are soft as any other tyre which can be called the best tyre. side walls make a tyre soft or hard not the tread itself, how do people check for hard or soft tyres, u tell me?
its the wrong wway, in reality, tread should be firm and side walls should be soft, this makes a ride comfortable and improves grip at the same time.
we press a tyre from its tread and then give a fatwa that it is a hrd tyre. decision is yoyrs anyway.
Best of Luck.
