Speaking of tires, inserts and rims...
Does anyone choose their parts based on weight, because the weight of the wheels are often neglected even though they play a huge part in rotating mass.
Its no use having a full lightweight titanium/aluminium drivetrain when your wheels are heavy too.
I have personally tried different combinations of the above 3 and found that weight variance can be very significant! Some inserts are almost half the weight of other brands, same goes with rims too (we often do not have as much choice where the tires are concerned).
