The durability of the pins is high, but the quality of the side rubbers is poor.
2019 December 2019 I received a December 2019 purchase, manufactured 21 weeks 2018.
This year 2020 I looked at Tire to do some SpikesPin addition work as it was winter.
There was a crack in the side. 。 The Tire was stored inside a shed, but the quality of the Rubber is too bad.
1Season December through the middle of May, I used it.
As for SpikesTire, it's better to add SpikesPin because it has less Pin.
The good news is that the Pin was highly durable and there was little to no reduction.
There are cracks in the sides, so I'll have to replace them when I finish using the 2nd Season this year....
