Tim,
Yeah, the Azenis are a truly great tire, especially considering the cost. I paid ~ 90/each for my 215/45/16's and am convinced that they outperform the previous set of s02 pole positions I had on the car. I've been playing w/ tire pressures lately and am still trying to get a feel for where I should be, but mid 30's up front and low 30's in the rear, seems to work well. But, this is on a FF car, so FR or MR layouts will probably need fine tuning. Also, I need to get the car cornerweighted before I go back to tracking it this summer.
I've alwyas stayed away from Goodyears, never heard anything good about them.
The re730s are ok, but you should try out either the s03's or if you can, get a hold of the Potenza re711's. These are a Japan only tire, but you can get them imported if you ask around. Slightly stickier than the s03, but less expenisive.
Another couple of interesting tires coming down the pipeline is the Kuhmo Ecsta MX, being developed to rival the Azenis in grip and low cost, we'll see how it does. I've never really like the ecsta 712's, but these might get me to switch. And, the Dumlop FM901 that just cam out, allegedly leap and bounds above the W10's they replace but they still won't rival the best street tires on the market, namely: Toyo t1-s, potenza s03 pole position, falken Azenis, and the ecsta MX. Man, I'm way too into tires!
Steve,
The Nitto 555R's are great drag tires, however, they lack the side wall rigidity that's neccessary for track/auto-x use. While the sidewall stifness may be OK for street use, it will fail to be of aid on the track.

Anyone consider Nittos? They are very stickey on the street but will last only 10-15K miles. I love Ferraris but come from a drag racing crowd, so please excuse my ignorance if I'm way off base. |

Sorry, i meant A3SO3 hoosiers. Hugh, my friend won the novice street prepared class on Azenis's, they had enough traction to let him 3 wheel it around corners. The car i drive in Autox events really needs new shoes. The 16" bridgestone RE730's in front are bald on the shoulders and have maybe 3/32nds of an inch in the middle and the new 17" goodyear F1 GS's on the back are just horrible. (the front and rears are different sizes because the new rims are being done one half at a time) But the goodyears are just crap. No tire pressure adjustments could make them work. The worn and heat hardened RE730's gripped better. |

Tim,
Did you mean the Yokohama/Advan a03r's? In that case yes, the a032r's are an amazing tire, even for the street. And, I've had Yoko AVSi's, Bridegstone so2 pp's, tracked ao32r's, and currently am using the Falken Azenis, which are awesome I might add. Unshaved and new the a032r's have just enough tread to get you by in a light shower, but in heavy rain I would not reccomend them, at all!
They are much harder feeling and noisier than a conventional street tire, but the grip is unbelivable. I would reccomend them for someone who is looking for the stickiest street tire available, but I should also say that the tires will not last nearly as long as a conventional street tire, they're just too sticky.
Common rule of thumb, if the treadwear rating is 200, tires will usually last about 20K miles.
As far as the Kuhmo Ecsta V700, I have heard A LOT of very good feedback on these tires, but have yet to try them, but they will be my next track tire. Also, the v700 is say to be of nearly identical composition as the full slick offered by Kumho, the victoracer. Making them even more appealing. Read link below:
http://www.kumhousa.com/pages/ev700special.htm
Chris,
I say you go for the Kuhmo v700, they are less expenisive than the Michelin, and as I mentioned above are rumored to have a high degree of homogeneity w/ Kumho's full slick victoracer tire. Only draw back to the Kumho is it's VR speed rating v. the Michelin's ZR, which comes down to weather or not you'll be exceeding 168 mph, will you? Anyway, my vote goes toward the Kuhmo. If it were a choice for the street b/w the p zero and michelin pilot sports, I'd get the Michelins then. But for the track, and specifically street slicks you wont beat the v700.

Yeah, the Kumho V700's kinda suck, they're better in the rain the hoosiers though! |

Agree with Mark McKenzie re: DOT tires on street. That said, seems you're planning to go another way at this point, Chris. For your current needs my pick would be the Hoosiers. Though the tire Tim referenced is cone-dodger specific. For the track stuff you're planning, the R3S02 is perhaps the better choice. May wish to try Luke at TireRack (888-981-3953 x362), he has been very helpful for me in the past. |

This is a good question. After autocrossing yesterday my friend with the camaro wants to get a set of slicks for his original rims. People suggested Hoosier A032's and Khumo V700's. They said they offer good grip and are progressive (something slicks are usually not). Anyone have any experience with these tires? |

Hoosiers are about the best, but probably not the life as the others. |

OK, I did it, I just bought a set of 18" rims for the track.
I'll run my stock wheels with p zero's on the street.
Now I will have to decide on slicks, Hoosier? |

I forgot about that with those tires. Between autocross runs it takes me 15 minutes to remove all the pebbles stuck into the tire. Sometimes it's so much you can barely see any tire. |

Not long ago, I posted my experience with Hoosier's DOT RS303 Slick as a street tire. They are DOT approved, and I love them on the track. I thought they'd be a great stree tire, since the car never sees rain, and isn't driven many miles.
However, in reality they're a pretty poor street tire. They don't have much grip at all when cold, they throw sand, pebbles, very small rocks... all over your car, and they tend to "dart" especially on tar strips.
Of course, your mileage may vary, and the Michelin's could be a better street tire. |

The Kuhmo V700's , Hoosier A03 or R03, or Toyo RA1 are great DOT legal racing tires. Full tread ok for rain, but I would go shaved for the dry on any of them. The Toyo's have the deepest tread not shaved and are prob the best out of the 3 for rain. I don't think they make a 335-17 though. Who knows. |

What about a set of Hoosier cheater slicks? You'd be nuts to drive them in the wet, but in the dry it would be hard to beat. |

Chris, a P zero with tread will often last less than a race tire on the track. The tread causes squirm which causes more heat and street tires will sometimes chunk under these conditions. I'm not sure about the street use, but I would run shaved tires on the track to get longer life out of them. I shave my track tires to 4/32. |

Since I only got 1,600 miles on my street tires on the rear of my F40, Tire Rack is reccomending Michelin street slicks, does anybody have any suggestions?
My friend Grant is saying get a second set of rims, slicks for the track and P zero's for the street, hate to spend the money on the rims, but... |
