Ah, now that makes sense. Performance tires are very sticky and designed for high traction. Yeah they wear fast, but that is by design so that they can stick when the power is applied. My last set of tires were 225/50-16's and at 80 MPH I could easily break the tires free. Now with my 275/40-17's I have a much harder time breaking the tires free, which is exactly why I bought them. If the power can't be put to the ground, what's the point of having high horsepower? A friend of mine is pushing almost 1000 RWHP in his Supra (he did 853 RWHP with his automatic transmission, but just changed back to a 5-speed which should free up about 100 RWHP) and he has to run drag radials as street tires, and even then at half throttle he can still smoke the tires doing 80 MPH.
Now for the low horsepower cars like my Geo, sticky tires are useless and a good hard tire is desirable. Hell, my tires on my Supra have a max PSI of 50, but I run about 30 just so I can try and get traction.
