I have the Dunlop SP Sport A2 tires with 650 miles. Previously, I had Michelin Energy MXV4 Plus. The Dunlops give better handling and a better on center steering feel than the Michelins. They are a bit harsher over sharp bumps, but the ride is still fine. So far, I am happy with the tires.
After looking at the reviews at tirerack, I eliminated the Bridgestone 950s, because there were a few really bad comments about snow performance. I'm in Wisconsin, and I need something that will get me through the winter. The Dunlops looked to be the better all-season choice.
Instead of sticking with the 195/65/14 size, you might want to upgrade to 205/60/14. It's more money, but if you're driving a lot it could be money well spent. Your speedometer will be off very slightly, but not by much. Go to
www.miata.net/garage/tirecalc.html to check. Dunlop has a brochure available with sizes. Also, they have a website at
www.SpSportA2.com, but the site was not working.
Despite what some people have posted, these tires will not "transform" your car, but you will notice a difference.
