I need 4 new tires for my '04 RC ram srt10, which would you suggest me to get pirelli Scorpion Zero Asimmetrico or BFGoodrich g-force tires? right now i am having pirelli scorpion zero on mine. Which would you suggest me either these or another?

Both tires are very good. If you ever see snow, the Pirelli is the better choice, because they are an all-season tire and can handle some light snow. The BF Goodrich is designed as a summer tire. It has better wet and dry traction, but no snow capability.

there have not been alot of snow in mass, so i guess i should go for bfgoodrich g-force?also i have heard that pirelli does cause virbration

Summer tires will be very scary in even a little snow, so factor that into your decision. The Pirellis should not give vibration as long as they are balanced correctly and have no defects. Any tire will vibrate if it is defective and/or not balanced correctly.
