I decided to switch to an energy formula instead of the standard yokohama. The weights didn't add up to more than 15 grams each, and it was put up and balanced with a thud. The automobile had an immediate transformation, becoming noticeably less stiff, tenacious in bends, and quick while braking. The attributes valued by consumers come in front. Concerning the deficiencies, after only one month of use, it looked dreadful. It appeared as if a kama that had been used for five years had been used; instead of being black, it was a kind of brown all over. Aside than that, I haven't experienced any issues, and I'm pleased with the tires. I collapsed quickly, and none of my extremities exhibited any signs of swelling. It's true that I got stuck on something with the back wheel, and it did break through a hole that was about half a centimeter in diameter for me, but after that, not a single rubber could take it. I patched up the damaged rubber, and then installed it on the backup tire. And with that, the flight will resume its normal schedule in a half year. In particular when it is raining, it is to one's pleasure that the water barriers pass without a hitch. I strongly suggest it to everyone!
