Dimension 215x45x17. Lost one spike during the season. around the spikes rubber gnawed. the spike is holding up well. after 120 the car starts to float on the road, it is to float, at the same time the steering obeys well and the trajectory is predictable. noticed such a nuance, when entering a turn on clean asphalt, the car seems to rest first, and then goes along a given trajectory, if you turn the steering wheel. all repeats. under heavy braking, the abs starts to work much earlier than on friction rubber.
