Mass is the better term for the added size.
Mass deals with more than the term weight does.
Mass - definition of mass

I was comparing a ranger sized truck to a F250. The largest motor for a ranger is the 4.2 V6, a motor that isn't even an option for the F250. There is probably a ton difference between the two vehicles.

Mass and weight can get complicated, just keep in mind that weight is conditional and mass is not.

I know Jack recently talked about tire size on another thread where he compared the mechanical disadvantage of the larger tires but I dont remember what it was called. I'm sure he's got the formula somewhere.
