At first I thought the Nokians were slightly noisier, but so slightly I could barely be sure. (The expert guy at Cal Tire who mounted the Nokians said they would be quieter for sure.) After 3000 km, I think the Nokians are probably quieter than the Nexens. I wish I could drive a Nexen-shod Kona to be certain of that. I'm hoping that another Kona will turn up at the BMW Car Club of BC's "Dancing with Cones" event on April 13th.
