I purchased a kit two years ago and skated for a total of two seasons. A hernia was discovered on the inside of one of my tires when I was changing it for the winter. I felt bad about spending the money, so I went out and purchased two more tires of the same brand for the front of the vehicle. You should have put the older ones in the rear. At first, the tire fitters were completely unable to balance the wheels once they had been fitted with the new tires. They advised taking a week off and then coming back to see them. It's possible that they're rolling. I rode, but I stopped at a different tire shop beforehand. There, the maestro also played the violin for an extended period of time. In the end, however, I was able to maintain my equilibrium. I hung a weight that was 80 grams in one particular location. It seems like a lot.
