Thirdly, while noise was OK at first, it gets considerably worse the more wear you're dealing with, so much so in the Sonic that you would get out of the car after long journeys with ringing in your ears and a headache.
They feel pretty firm too and aren't great at absorbing bumps as much as other tyres we've had, so they were uncomfortable at every stage of their lives. We were, at one point, thinking that the cars were the problem; Then we swapped the tyres out (Sailun Atrezzo Elites on the Trax and Toyo Proxes CF2's on the Sonic) and they're both completely different cars, so much more comfortable to drive, much more reliable grip and so much quieter.
I'm surprised we had such bad experiences with this tyre, because Continental are usually a great brand - but think they're just not well suited to our cars.
