Guys: I think a tube would give you trouble because of the tire inflation sensor in the wheel. Not sure what it would do if you remove it, (maybe just a light staying on the dash or maybe nothing) and will the valve stem will fit thru the sensor hole? (remember that the normal hole on a wheel is a fair size to fit the tapered valve stem). Also, is the rim smooth enough for a tube, because they don't run a tube, they may not have the rim deburred enough. However, I think the donut idea has some merit! Let us know!
