We do everything different here , for the tyrant govt . We have steel belts in tires .
Smarter , free'r countries have better technology , they know how to make tires ... They do not put steel wire in radial passenger car tires ..
Thats why we quote German engineering , they have less tyranny , forced technology , than we do . If Germany needed to fly to the moon , they would have it in 1/10 the time , 1/100 th the cost , and ultimately they'd question the need to go there in the first place .. They can think for themselves !!! Thats why we buy MB/BMW ..
Quit wasting your time quoting the US technology , it is govt forced .
150 years ago we had engineers , not today , only Luddites , sell outs , phony govt employees ...
