Most cars don't come with a spare now. Runflat tires or a small compressor with tire slime is what the 2013 Kia Optima we had came with.
Saves weight and space in the trunk. Also drops the cost of every car.
Bmw uses fun flats or the M cars get a compressor and slime.
Figure if they save $100 per car across the lineup......huge money savings.
U going to drive some cars this weekend ??
