Hey Guys, I apologize in advance because it seems wheel spacing is a relatively common topic, however none of it makes sense to me! I have a 1994 Vette and I love the look of the gloss black centennial cup wheels off a C6. I'm not sure but I think these particular wheels have a different offset than regular C6 wheels. Also, I'm due for new tires and I think it's time to bite the bullet for these wheels. (Plus I'm having some difficulty finding tires for my OEM wheels as Michelin discontinued their OEM Replacement tire) I guess my question is, are these wheels offset differently or can I use the 1.5 inch spacers all the way around to run these wheels?

Centennial:
Front 19 x 10" with a 40mm offset Rear 20 x 12" with a 59mm offset 94 z51: 17x9.5, 54mm offset The bigger question, is will they rub without sticking out? Rear frontspacing: 12 / 2 - (59/25.4) + .25 = 3.93" 9.5 / 2 - (54/25.4) + .25 = 2.37" Rear backspacing: 12 / 2 + (59/25.4) + .25 = 8.57" 9.5 / 2 + (54/25.4) + .25 = 6.63" 1.5" spacers will prevent that extra 2" of backspacing from rubbing. But it's gonna make the wheel stick out about 3" vs stock. Even with no spacer it would stick out 1.5" more than stock. I didn't calculate the front, but use the same math. You should first figure out how much backspacing the car can fit, then we can calculate what spacers (actually adapters) you'd need. Make sure and get the hub centric ones, they are less dangerous. |

Screw Michelin. There are so many better choices for tires out there. If you want to spend some money, the Goodyear gsd3 is a good street option.

Yeah that makes sense. I would imagine the back will clear easier than the front in that they don't steer as long as the suspension travel doesn't allow them to rub on the fender, control arms, and maybe even mufflers when I hit bridge abutments and such. (oh well, I guess an exhaust is in my future then too!)

And out of curiosity, why don't you like the Michelins? I have the old Goodyear Eagles now and have gotten decent mileage out of them, even for having a heavy foot but someone told me the Michelin Pilot Sports grip nice too. |

BEG PARDON FOR INTRUDING; I CAN'T SAY WHY CC IS OFF MICHELINS, BUT I HAVE NOT BOUGHT THEM SINCE 1970 AND NEVER WILL. IT WAS FOUND OUT THAT THE MANAGER OF THE DAU TIENG MICHELIN PLANTATION WAS FLYING VC ON AIR RECON IN HIS PIPER CUB. I KEPT SUGGESTING A "FRIENDLY FIRE" ACCIDENT, BUT IT NEVER HAPPENED. BE DAMNED TO THEM! |

Well I guess that's as good of a reason as any! I guess it only makes sense to go with Goodyear, as far as I know, they're still American made. |

Generally speaking, no they aren't. Nor are Michelin. People must think so by the prices they get away with though. You'd have to research that particular tire model to know for sure.

That's a great idea! I wasn't sure that they did and if they did, whether they were of the same quality. From what I've gathered through searching around, C5 wheel dimensions will fit a C4 without clearance issues so maybe I could go that route too. I do want the wider tire look, not to mention the ease of finding new rubber. I've called all the local tire places and gone through the same spiel with them, give them the sizes and whatnot and they give me the "let me do more homework and call you back" and they never get back to me. Another motivating factor in a wheel upgrade. |

Well I'm sure the Wal-Mart Goodyear's are made in some 3rd world country for pennies on the dollar! I'd like to think my tires were made of a slighter higher quality than that... But i'll take your word for it that the Goodyear GSD3's are a good tire and that's what I'll go with, even though it's going to punch me in the wallet pretty good. Now I have to figure the rim situation out so I know what size to order! |

We got them from West Coast Corvettes, because they were one of the first to market; I think there are more choices now. Another shot: |

I do love the look of them. I initially got the idea from a youtube video of a 1990 Vette with an LS7 swap and its similar to my car's color and the wheels look great on it. This is going to be my ONLY set, that's all my wallet can afford right now. The car doesn't get driven from November to late April (I live in New England) so these tires should last me 4 years or so. Hopefully the wheels will last forever haha |

I knock chinese parts all the time, but I honestly haven't realized the benefit yet to spending lots of money on wheels. I have chinese wheels on my vette and tacoma. I know the OEM castings usually save weight, but otherwise I've been satisfied with the various sets I've used.
Although last time I was at the track a porsche broke his wheel and nailed the concrete wall, I wonder what wheels he had on there. But I've also seen a Fikse wheel that failed in a similar circumstance and those are close to $800 each. |

Yeah I'm weary of off-brand wheels and the only reason being that I live in New England and theres only 2 seasons here... Winter and Road Work. So the roads are in rough shape and I have D'ed up my fair share of rims so that's why I want to make sure I get a good quality wheel that I'll be less likely to put a flat spot in. As much as I try to avoid the nasty potholes, sometimes they sneak up on ya. Makes me wonder if the old steel Barrett stock car wheels are the way to go sometimes haha

I bet wheel diameter would be just as important if not more, regarding potholes. |

In my opinion, Michelin makes the best tires in the world.
War crimes and international marketing, not withstanding. However, BF Goodrich is owned by Michelin and gets their engineering from Michelin, but in an American made tire at a lower price point. I have BFG gForce KDWs on my 92 and recommend them to anyone. Falkin, Nitto, Toyo, Bridgestone, Firestone, Continental and Cooper are all worth looking at. |

I do like the "traction bar" down the middle of those, especially in the front for steering, they seem to grab better in all conditions. How's the mileage on them for you? |
