OK no one is reading between the lines here

If you are weighing the wheel without the tire at home; that must mean you have some aftermarket wheels

 

Gary is holding out on us.

 

He already has an extra set of 04 stockers. How many rims does one guy need?

Come on Gary, spill the beans.

 

You guys are paranoid. He got an extra set of wheels to run on the track.

 

Rich,

I weighed the wheel tire combo then, I weighed just the spare tires I had, subtracting the two to get the wheel weights.

(Wheel + Tire) - Tire = Wheel

Like I said in the original post, there is likely some rounding error present in the process and scale.

All the weights:
Fronts: 40 lbs - Wheel and Tire
Rears: 47 lbs - Wheel and Tire
Fronts: 18 lbs - Tire
Rears: 24 lbs - Tire
----------------------------------------
Fronts: 22 lbs - Wheel
Rears: 23 lbs - Wheel

 

At this moment, this guy needs 6 sets of wheels and tires and 2 more sets of tires, all that have purposes.
