Thanks for the information. It's nice to know there are much better ones out there. But then I've always believed you *typically* get more by paying more :)
The reason I chose the Firehawks is the balance of "long wear" and "wet & dry stickiness" and price.
On the web site you sent me (thank you) I see: Both for 96 GT Convertible stock 17" rims and picked to show only high perf tires (V, W, Y, Z) and Extreme Perf Summer, Max Perf Summer, Ultra Perf Summer, High Perf Summer, Grand Tour Summer, Track & Comp DOT, Ultra High Perf All-Season, High Perf All-Season, and Perf All-Season:
PZeroNero Rosso cost $182 per tire. PZeroNero M&S cost $154 per tire The Firehawk Wide Oval are $144 per tire.
Here are the ratings: Would buy again. Firehawk: 8.5, Nero: 5.6, M&S: 8.3 Hydroplaning Resistance. Firehawk: 8.4, Nero: 7.3, M&S: 8.6 Wet Traction. Firehawk: 8.5, Nero: 7.5, M&S: 8.6 Cornering Stability. Firehawk: 8.5, Nero: 8.5, M&S: 8.7 Dry Traction. Firehawk: 8.8, Nero: 8.8, M&S: 9.0 Steering Response. Firehawk: 8.6, Nero: 8.4, M&S: 8.7 Ride Comfort. Firehawk: 8.4, Nero: 7.2, M&S: 8.6 Noise Comfort. Firehawk: 8.2, Nero: 7.1, M&S: 8.6 Treadwear. Firehawk: 8.5, Nero: 4.9, M&S: 8.2
So... I'm seeing the PZero M&S is indeed a great tire for the money! Only $10 more than the Firehawk. BUT three things: (a) I can get the FireHawk's local so I don't have to pay for shipping; (b) As you mentioned, treadwear is superior in the FireHawks; and finally (c) The M&S only beat the Firehawk each time by like .1 or .2 and once by .4. So if you add up all these factors, to me, they are pretty equal tires... except.. well.. shipping cost definitely puts those out of my budget. I
*will* look around, though, to see if any local guys sell those. Even then I don't think I'd buy those tires because of treadwear factor (I like my tires to last longer and please consider that if you re-tested the Firehawks 9,000 miles into use against the M&S 9,000 miles into use, because of tirewear, I think you would then find the Firehawks, at that mileage, to have much more grip... probably be superior then in every category to the M&S... so yeah, when they are brand new, you have a better tire but they obviously wear quicker.
Finally, I'll admit one thing: Those PZero's *look* much nicer; they seem to be lower profile. But I'm not as concerned about looks as I am with the price/performance index.
Thanks for stimulating me to do this research so I am even more sure now that I dig the tires I purchased :)
