A Mazda Miata weighs in at over 1K more, so load ratings aren't compatible. Plus, the obvious of missing a fourth tire. We can surmise that a grippy auto tire might translate into a grippy tire for a Spyder. Also, a long tread life rating may also mean a less grippy tire. It'd be nice to see a deep pocket group do some actual auto type testing on a Spyder, but you know it ain't gonna be BRP. Hell, I'm liking my "Mike" recommended Vredesteins on my fronts. I'm also really liking my 215/60r15 Goodyear Ultra Grip after years of year round use on a few squads. My rambling is over :). Carry on .....
