Im gonna tell you a story about the dude with a real nice Porsche, and his flat tire, COSTLY, experience. Any of you know Porsches, they all come with an air compressor, nice little logo on the plastic carrier deal, pretty cool. They come with becuase in the event of a flat, the spare is stored under the hood flat, space is limited in little cars like those. So, this friggin rich dude pulls into the shop, on fire. I put the fire out(almost), put it on the lift and put out the rest of the fire. Then I asked him to come into the shop and explain to me what exactly he did. "I got a flat, put on the spare and drove here"
In about 4 miles, he destroyed the following:
1) Paint Job - fire melted it to bare metal, whole car painted
2) spare wheel and tire
3) brake line, rotor, pads, caliper, couple other things....and in a car like that you do both sides, not one.
4) oil cooler lines, oil cooler(line burnt up to the cooler, melted it)
5) trunk carpet
6) passenger side tail light housing, wiring, bulbs
7) soft top(bottom right corner melted)
He never inflated his spare, I showed him the compressor and got a "Oh thats what that thing is for".
It has traction control, just like our Jeeps. So, all 4 wheels have to spin at the same time. Not for nothing, driving anywhere on stock spare when the other 3 are 35's, not good to do.
Edit - forgot to tell you why he burned, the traction control, or for us its ESP which eats rear brakes......Uses brake pressure to make sure the spinning wheel(which will be spinning faster) slows to gain traction. Smaller spare = spinning faster, and after a while red hot rotors ignite pads, then lines, then your screwed......
