Ever since i replaced my tires recently i get a slow vibrator or what i would call a wobble while accelerating or decelerating quickly (engine braking). It's not really noticeable whole cruising at a fixed speed. At first i assumed it was a chain tension or maybe alignment issue but after ruling that out I'm at a loss. I'm going to take my rear wheel back to the shop that installed my tires tomorrow to have the balance checked. Maybe just removing and reinstalling the wheel will help. Is it possible i put the spacers on the wrong sides? i was pretty careful to remember where they went but i have to question everything until i rule it out. Any ideas on what might be causing this?
