I'm afraid for the spikes, they don't inspire confidence. The start is as smooth as possible, with a lot of throttle. Before that, there was a Gislaved Nord Frost 100, so it left the traffic light with axle box (it steered better on asphalt than the Nordman), didn’t bother with running in at all and not a single spike flew out, the rubber around the spike didn’t crumble. I bet that in the winter the Nordman will win back over the ice and over the snowdrifts. Otherwise it's really sad :( : on ice and on snow rolling, as expected, it keeps perfectly, the mileage on this rubber is 4000 km, 90% dry asphalt, the spikes are all in place, the noise has become less (or I'm already used to it, xs)
