whats the difference?
what the difference in the 120/60/17 and 120/70/17 apart from the size?
I used to have an open mind but it fell out!!

Both are for a 120mm wide rim (so I assume we're talking about a front here)
Both are for a 17" diameter rim.
On one, the profile height is 60% of the width (72mm), on the other it's 70% (84mm)
So your rolling radius of the wheel will be 12mm bigger - or about 4%.
In terms of what this actually does to the handling, etc. I'd guess it might turn in better because it will be more inclined to 'tip' onto the side of the tyre, but this assumes a lot of other things being equal. We'll have to wait for one of the racers to answer properly!
If nothing else, your speedo will read 4% lower.
