Asked this in other forums... figured I would get others opinions from this site as well.
I'm running with Raptor Riken HR 185 60r14 82h M+S tires. Decent tread left, 28 PSI. And the last 2 times that it rained when I went out and drove... I fishtailed. The first time I took a 90 degree turn at 10 mph and completely spun out. The second time I was extremely weary of my car sliding in the wet... and I was taking a very soft curve on ramp at 40 MPH in fourth gear taking my time. The revs were under 2500 and the cars in front of me drove atleast 10 mph faster than I was... and the car behind me was near tailgating. I slid out and let off the gas and corrected myself... but I still slid out! On this particular on-ramp... I would have no problem taking my old car (95 Lumina) 70+ MPH on to the on ramp while raining... or this Miata onto the on ramp at 90+ if it were dry.... (I don't do this, I'm just emphasizing the lack of turn, it's very near a straight line) In my entire history of driving (albeit just 4 years) I have fishtailed 0 times.
Would my tires be a probable cause? Or am I just not used to a featherweight sports car?
