Current tires on them are
285/40/ZR15, 225/50/VR15 . RIMS are 15X10 & 15X9 They came off of a '79 930. Tire Rack does not carry the 285's in 15" for the Kumho's i'm looking at. WW914CPD? (whatwould914clubpeopledo?) FYI, I will be using a BF2X4 to clearance the fenders.... The PO encluded a quart of touch up paint.

Is there a question there? I've read it three times. (IMG:http://www.914world.com/bbs2/html/emoticons/unsure.gif)
There is a tire calculator in the 914Info section at the top of this page. |

Hey guys, sorry for laggin'...
Met a new single massage therapist and she required more time today than I had expected... (IMG:http://www.914world.com/bbs2/html/emoticons/biggrin.gif) Yep dems' da' Gotti's. I'm thinking powder coating them black or flourescent purple to match the valve covers... (IMG:http://www.914world.com/bbs2/html/emoticons/huh.gif) I prefer less sidewall and thought 285 represented sidewall height. Yes/No? My question is isn't there something about "aspect ratio" that the "285" represents? I have no idea what that means exactly... When I drop that number doesnt the sidewall decrease? (so 225 40 ZR 15's simply have a lower profile than the 285 40 ZR 15's ???) Roger (IMG:http://i17.ebayimg.com/01/i/05/2a/61/9c_3.JPG) (IMG:http://i24.ebayimg.com/02/i/05/31/12/38_3.JPG) |

Oh and Mark,
My question was is if I cannot find 285's what would the club people do about the right size for these rims. (IMG:http://www.914world.com/bbs2/html/emoticons/biggrin.gif) |

roger
285 = width the next number such as "40" is aspect ratio, or sidwall height. 40% of 285 and the last number is rim size = 15 285/40/15 |

I have a contact of someone who was getting 345x35x15 Pirelli's new. They were going for about $600 a pair. I think he's out of them now but my point is they are making the tires just in limited quanties.
The Countach and the 911 rsr shared the same tire as far as I know. |

285 is width in mm so 285/25.4=11.22 inches a 225 on a 9" rim is stretching it....normally 245's are the preferred width, but you'll get quicker steering with the 225's |

yup...herr mueller is right. i got 225's on 8's, 225's are even a tad small maybe on 8"s, so a 9" would be nuts |

225's on 9" rims, would make them low rider wheels (IMG:http://www.914world.com/bbs2/html/emoticons/happy11.gif) |

Oh noooooo. (IMG:http://www.914world.com/bbs2/html/emoticons/ohmy.gif)
So now that I look at Tire Rack I see that there are zero tires to fit the rear rims. Hoosiers..., well I was thinking of this car as a street rod/road racer/daily driver. Hmmmmm (IMG:http://www.914world.com/bbs2/html/emoticons/laugh.gif) I USED to believe that there was no such thing as too wide....

don't run the current tires. pirelly stopped making those sizes 15 years ago and those are probably hard as a rock by now ... i have been looking for that exact same size for over a year now, no luck ... if you do find new tires in that size, let me know where!
