Porsche wheel weights

Interesting point here for future reference is that for the same overall diameter alumimium wheel weighs more that tyre side wall.

(plucking figures from the air) A 245/55x15 tyre/wheel combo will be lighter than a 245/35x19 combo

At the front of a bug this will matter a lot as the sprung to unsprung weight ratio is relatively low.

Yep, very true imo, but....for a circuit racer it also matters what the grip level and handling caracteristic is for both combos.The lower side wall will have better handling due to stiffer side wall giving much better steering respons.
Its never that simple
