Anyway, what will happen if i change from 17" to 15"? What i mean is, is there a change in driving? Because 1sz-fe is not that good when it comes to power.. Im just curious if its worth changing the wheel size..

A smaller wheel will decrease your rotational mass, so you will be able to accelerate quicker. Lighter wheels also tend to give better handling.

Revolutions per mile is the number of complete turns of the tire when traveling one mile (1.6 Km). A tire with a larger diameter will make fewer turns when traveling one mile, a tire with a smaller diameter will turn more per mile.
