I have used many. (IMG:style_emoticons/default/dry.gif) ( $$$ )
Falken Azenis-YokoA032r-Hoosier A3s04 and R3s03-Kumho710's. I like the 710's the best. Mine are not sticking on the a/x track like when they were new. Too many heat cycles. I need to keep one set for a/x and another for the track. Hoosiers are on closeout sale right now, I have a pair of two hour old Yok A048's and Toyo RA-1's are another good choice. What seems to work for you? Slicks are always an option, too. KT |

Sanctioned events probably have a spec tire or a limitation by class or run group.
I have R3SO4 for the event this weekend. I don't expect them to last past the one day. Next set of tires will be take off slicks. |

Some tire compounds are designed to heat up quicker than others. There's an optimal temperature range for the tires, and if they retain too much heat between runs, they start to go off, and get slippery. The spraying of water on the hot tires cools them down, so they don't overheat durring the next run.
Some tires are better than others at handling heat. Falken Azenis tires for example, you'd think would be fine. They're not super sticky race tires right? Bzzt. They begin to go off at surprisingly low temperatures compared to a race tire. So even those tires often need spraying down between runs, especially on heavier cars... -Josh2 |

I started on hardball street tires....205s at both ends.
Then: Victor racers 205 & 225s Hoosier R3SO3 225s at both ends. I learned about the longevity of tires on 914s from the first 2 types Hoosier A3SO4 225 at both ends Hoosier 10 X 22 X 16 R35 slicks both ends Hoosier 10 X 22 X 16 R35 R & 9.5 X 23 X 15s F Both in R35. |

Kuhmo 710s for me. I still need to drive to events and 710s are bare minmum before I go to race slicks. Quite a few people drove on 710's to the SCCA event I drove in this past weekend. They reported having few problems driving shot distances on these tires.
What are race slick equivalent to 265/45/16 and 225/50/16? Where is best place to buy race slicks? I'd love to run the last couple events this season on real race tires. |

Slicks are problimatic, size wise. The cantilevers are made 7/8 X 15 wheels. Normal slicks are big & go bigger.....generally, they take a wheel the same width as the tire......10 inch tire, 10 inch wheel.....these are smallish. .....metric cross section would be in the 255 range. Compounds from from one make to another don't have any relationship that I can discover....but for AX, you want the softest they make. Hoosier's & Goodyear's website list the sizes available.....and their not getting cheeper |

So if I have 8" fronts and 9" rears and run 265 in back and 225 in front what would specific sizes be? I need to be careful not to go much wider than the metric sizes as my fronts just barely rub when I make shrp turns and rearss are real close to rubbing. [/quote] You don't say what diameter wheel you are using. Cantilevers are for a 15 inch wheel. I don't wanna lead you astray cause, frankly, I don't know what will or won't fit to your application. You * should* be able to fit something like Andy is using on his similarly flared car. Those are not the smallest slick Hoosier has.....but it's close. Go here for the Hoosier selection: https://www.hoosiertire.com/rrtire.htm You'll have to search for Goodyear stuff as I don't have that bookmarked. |

Grant, since you are running five lug. get a second set of rims.
Aren't a set of 7x15 Cookies around $200? Randal may be able to help you find tires. KT |

Just ran my first event at Streets of Willow on 235/255 Toyo RA1's on 17" Fikse wheels under my GT flares. The RA1's work great in the heat at Streets. (It was about 95 on Monday. Hate to think how much hotter it will be for the next POC event at the end of June.)

Andy's cantilevered slicks MUST be mounted on 7" wheels.
I will be fighting this also when it comes time to buy the next set of tires. my Diamond wheels are 8" wides and my centerlines are 8.5" wide The slicks I have on the Centerlines are barely suitable for AX. I highly doubt they wil stand up to track stuff. Hoosier C3000 22 X 9.5 X15 compound R25 designed for Formula Atlantic cars. Guess I need to bite the bullet and buy some 7" wheels |

Sorry, Andy, but that is not correct.
You may think/do what ever you want, tho (IMG:style_emoticons/default/biggrin.gif) You want pics of a guy that runs Goodyear cantis on 8s and has been doing it for years? I'm doing it now with Hoosiers....and yes, there is a good reason for doing so.... not that you would be interested since it can't be done. (IMG:style_emoticons/default/biggrin.gif) |

I'm pretty sure the chart is showing specs for the tire on the rim it was mounted on.
All charts are this way. EDIT: Most charts are this way. I don't know anything about the tires you run. The tire has to stretch...Otherwise it would be *impossible* to install (IMG:style_emoticons/default/chairfall.gif) (IMG:style_emoticons/default/popcorn[1].gif) KT This post has been edited by trekkor: May 19 2006, 02:16 PM |
