Steel vs Aluminum Wheels

Would switching from Aluminum to steel wheels improve CCC?

Typically adding heavier wheels is like adding 4lbs of weight for every 1lb of wheel weight. There is about a 18 lbs difference per wheel going from Steel to Aluminum. Thats 72Lbs for the rear and 26 for the front.

I think it would allow for a better ride as thw wheel/axle could respond faster to road conditions. and it would help is startup due to rolling resistance decrease.

However i am no sure the factors that contribute to the GVWR. Not sure of axle weight rating ins dictate by weight pressing down on the end of the axle tubes or the sheer forces on the axle its self as it tries to spin under load.

  • I would say no.

    The term is unsprung weight. Very important number in sports and race cars.

    But the weight the springs, axle, frame sees doesn’t change.

    Tires, yes.
  • GVWR and CCC are decided by the manufacturer. You can beef something up if you wish, but it does not change what you are allowed to weigh, or carry according to the law or your ins co.
