I swapped wheel on my old VW years ago. Went from stock steelies to 17" low with profile tires. Weight was the same but it was all on the outside and that alone made a difference. Could feel it pull a good bit harder.stock '98GT 17" wheels with 245/45 tires 50LBS
Stock '00GT 17" wheels with 245/45 tires 42LBS
I just pulled 32-40LBS of rotational weight off of my car, the difference can definitely be felt.
