Weight of each steel road wheel of A2 = 63kg
Weight of each rim wheel of of A2 = 15kg
____________
Each Rubber Composite (RC) Road Wheel = 45kg
Each Rubber Composite (RC) Rim Wheel = 5kg

_________________
Each A2 have 32 Road Wheels and 16 Rim Wheels. 2 Road Wheels are stacked together.
View attachment 1980
Meaning on each side A2 has 16 Road Wheels and 8 Rim Wheels
____________
Calculation of Weight Reduction of A2
Steel Road Wheels + Steel Rim Wheels
= (63 x 32) + (15 x 16)
= 2016 + 240
= 2256 kg
RC Road Wheels + RC Rim Wheels
= (45 x 32) + (5 x 16)
= 1440 + 80
= 1520 kg
Total weight reduction
= 2256 - 1520
= 736kg
So the weight reduction is a huge 740kg on just wheels. It doesn't even includes weight reduction of using composites + high nitrogen steel on chassis and a possible rubber composite track as well.
