Of course there is the ongoing debate of a 180 series rear tire ruining the SVs handling. I'll just say this, it has slowed down the turn in speed but by no means has it "ruined" it. Anywho, the effect that I'm wondering about is the height of the tire itself. By switching from a 160/60 to a 180/55 has the rear ride height changed? Logically I would think it was lowered seeing as how the aspect ration went from 60 to 55, but I'm not very well informed on that topic. I'm looking to return to my original set ride height that I had with the 160 tire, cause my front end feels slightly less responsive than before. Could I drop the forks a few more mm to compensate for the rear tire? Enlighten me please.
