I took for nine, 13 radius. I use my car for hunting trips. and the point was to ensure good patency on dirt roads. also good performance on asphalt. I am 100% satisfied. It doesn’t make noise on asphalt, it’s not afraid of rutting, it’s stable at speed, up to 120 (rarely) there are no problems, plus a really short braking distance, it doesn’t blow away when braking. reasonable consumption. )) now about pleasant things, the car rides on this rubber until it sits on the bottom, there are no problems on wet clay, it doesn’t burrow, expectations are fully justified, the pattern does not stick, winter, well, here, as a supporter of safety, I am of the opinion that good studded tires will cost much less in the future than the savings won by using one set of tires, albeit such a wonderful one. Therefore, I will not recommend it in the winter.
