There seems to be a problem with editing my previous rating. hence, I have written a new one and erased the previous one. The outcomes improved over the second winter. 1) It's relevant for everyone! Store-bought rubber has a "hairy" texture, which, from what I've read, significantly reduces its grip, especially on smooth floors. Before winter arrives, we need to get this hair washed. 2) Extremely supple rubber; add 0.3-0.5 psi to the recommended inflation pressure. It was quite useful to me and completely altered the characteristics. If you follow these two suggestions, you will find success. There is nothing better available for the price. Success to everyone!
