Story summary

Weight reduction in vehicles can enhance performance by improving acceleration and braking.
Modern strategies include using lightweight wheels to lower overall weight and rotational inertia.
Jonathan Benson of Tyre Reviews tested three wheel weights—20, 38, and 52 pounds—on a BMW M3.
The tests showed differences in acceleration and braking, but gains were smaller than expected.
For everyday drivers, actual performance gains from weight saving may not be dramatic.
