Theses PS2 tires are excellent. They are the Michael Phelps of max performance tires. Great performance in all areas. The first thing I noticed was the extreme ride quality and low road noice like a well rounded quality wine. Balence! My RX-8 handles more precisly.Diver confidence more improved than before. Every tire may perform slightly different on different cars but this performance report I'm giving is very true when placed on a stock 6-speed rx-8. 225/40/18 are the ones I used. Very low unsprung weight.Excellent in the rain too. Tight and planted to the road. Acceleration feels improved as well. The ratings on tire rack do reflect the real world performance when placed on the rx-8. The only thing I disagree with is the tire treadwear ratings. My ps2 tires have 33,000 miles on all four and had mazda's mechanic measure their remaining tread depth. The lowest tire depth is a 4 mm, two more at 5 mm,and one at 6 mm a 10 mm means new tire. What this means is I still have about 30 % or 1/3 tire life left, even after having 33,000 miles on them. Amazing! They could last as long as 40,000 milesor a total of three years. This is because the rx-8 has a good balance suspension 50/50 weight distribution, low cg. and lower torque than other sports cars 161 pounds at best. If it were a mustang, camaro etc. we are talking more than twice the torque which wears down the tread faster. They are heavier too. less weight helps. So if you drive a car simular to in size weight torque amount say like a scion FR-S / RX-8 get these these are a steel. They last long, for champaign quality performance in all of tire rack's rating areas. I just bought the PSS which I understand, in theory, they perform even better in all areas. Will send an honest, true report about them soon. Stay tooned! lol!
