Who told you your upgrade in wheel size is only 4 pounds more?
My 20 inch tires weigh 28 and 29 lbs each. The stock ones are much less, closer to 30 lbs rim/tire total.
Hey, even if its true that ur new wheels only weigh 4 more pounds, the physics behind it is quite simple... torque, and acceleration are related by the amount of rotating mass....wider wheels wider mass....lower acceleration.... haha guess payin attention in hs and college does pay off :-)
