I have come to the conclusion that you lack the basic understanding needed to carry on a conversation on this subject. Many of the points are going straight over your head.
I hope the OP can determine the answer to his question based on what has been posted. We really don't have enough information on his situation to give him a judgment one way or another. (For all we know, the tires might be completely different sizes, etc.)
Basically, if he is planning on running this combination for any extended amount of time, I would have to say that its a bad idea, based mostly on the extreme differences in the tire compounds. I think it *may* lead to some quirky handling...depending on his driving habits and usage. Plus, the RE070s will wear much faster than the HRi all seasons...especially with the Bridgestones on the front....(This could lead to a significant enough mismatch in circumference to warrant concern for the driveline)
