I agree,the 185mm factory sizes tires are too narrow in my opinion. I had to make adjustments in my driving because I'm use to my old MR2/Boxster S mid and rear engine platform. 195mm on a miata is OK, but put a set of 205mm tires and you will have all the grip you want trust me. If you upgrade to the stiffer FM springs and adjustable shocks on top of having 205mm tires, you will have one hell of a ride. Although underpowered, these cars are a pleasure to drive in tight technical turns.
