Slipperential questions and a brief other

there is a difference... they will handle diffrently... personally i'm not a big fan of 40 series tires/wheels for racing, they are harder on your truck because of the low profile nature of the tires and their increased weight... in certian conditions one will offer more traction than the other... there is also a very limited choice in tires in the 40 series size
