The Challenger's weight is not the issue. While it is relatively heavy, it only weighs about 4,300 lbs. In addition, a jack only supports about 25% of a car's weight (the other three tires are on the ground). See my previous post for an explanation for the absence of a spare and jack.
Carmakers are skipping the spare because of regulatory pressure to squeeze more miles out of every gallon of fuel. Ditching the 40 or 50 pounds that a tire and jack usually add to a car’s weight, helps to increase fuel economy slightly. It also incidentally increases automakers’ profits because they don’t have to pay for those parts. Another factor is that it increases trunk storage space, especially with large diameter and wide tires.
Instead, the factory gives you get a sealant kit. The problem with this is that it won't help you if a tire’s sidewall gets sliced or if the flat is caused by more extensive damage than a tread puncture. If you take long trips and want to be prepared for any type of flat tire, you might want to consider a spare-tire kit, which includes a tire, jack, and lug wrench. Expect to pay about $239.
That being said, if you don't take long trips, you may want to gamble and not buy a spare kit. Modern-days radials rarely get flats or blow-outs. Some options are to join an automotive club, like AAA, or buy a $6 tire plug kit. Using this prevents the sealant from fouling your tire pressure monitor sensor.
