A lot of under steer. being FWD we get understeer so down sizing, IMO, really degrades the responsiveness of steering.
this is far from true.

All of my race tires are 15". I dont have any steering response issues. Turn in is more of a function of the rest of the suspension and the brand and model of the tire, not so much the size.


but to the OP, you might not notice a difference between 16s and 15s.

one thing that hasnt been mentioned is tire pressure. I have found that If i have the recomende amount of air pressure (32 or 34psi or w/e it is) that i get a lot of tire slap and thumps going over expansion joints and potholes. I get a much smoother ride with 37 or 38 psi. however getting up to 39 or 40 psi starts getting rough again.
