3. It could be beneficial if you get the proper tires for the rims. Spare tire skinnys are not meant for drag racing. That's not to say that the tires wouldn't work but it is not a good idea at all, in my opinion.
Tires will be visually checked for condition, pressure, etc., and must be considered free of defects by the scrutineer prior to any run. All street tires must have a minimum of 1/16-inch (1.6 mm) tread depth.
Temporary spares, space saver spares, farm implement or trailer tires prohibited. Metal screw-in valve stems mandatory in tubeless tires, front and rear, on cars running 11.99 (*7.49) or quicker.
Doing some research on this it appears as though no sanctioning body gives approval to using space-savers on race cars. But as with all rules, it really depend on the quality of the track employees and their desire to enforce the rules.
