Dave,
re:"the best looking wheel on a 308 is the QV rim"
Hmm, Well, my '82 Euro 308 QV came with 390 TRXs, so I agree with you. The TRXs do have nice porportions of rim to tire...
BTW, the CR28s are V rated. |

Hi DJ,
E-mail me direct [email protected] regarding the 16" wheel group buy and I can give you some encouraging information regarding it.

The deafening silence heard after asking about an after market for the 390 rims answered the question. I'm going for the 16" rims. I saw a group buy about a month ago from Superperformance. Does this happen on a regular basis? Who do I contact?
Thanks for the input everybody, DJ |

140.00 a piece for the Avons sounds fair and being an all weather touring tire is the info I was looking for.
I don't like being restricted in brand choice either and that is what the TRX system is, a restriction in brand choice. I don't like being limited in what is available to me in type ,size, compound and profile when it comes to a tire. I may change my driving habits down the road but I can't change type of tire because of it's unique size and design. I will have to buy new rims to get what I want, like the 16" OEM rim with a 50 or 55 series profile. Actually that sounds like a pretty good idea.(Thanks Verell). I went through this on a TRX equipped Mercury Capri in 1982. The tires cost twice as much to replace as with another tire of equal performance. I couldn't sell the rims either because everybody was wise to the 390 brand limitations so I unloaded the car.
Is the resale market any better for excellent 390 rims these days? If there is a market in the concours crowd then maybe I'll go ahead and pick these up anyway and look for a deal on 16" later but don't get me wrong, I'm not into the 19" rims with rubberband tires either. Just want to freshen the look and performance of the car and still maintain it's classic form.
Thanks, DJ |

Okay, personal opinion here, but TRX wheels and tires "looks better too..." ? No way, the best looking wheel on a 308 is the QV rim, by far.
And I hate totally modified "franken-ferrari" hatchet jobs as much as the next, but by the same token, to hell with the concours crowd too. :-) It's a 308 for god's sake, not a LWB California Spider. BTW, DJ's car is a 78 308, so TRX is not original to his car anyway....okay, off soap box... |

DJ, another reason to go with the TRX tires is to keep the car original. For concours purposes that is a must. IMHO it looks better too. |

Im running 390mm TRX AVON CR28s. Cost me $140 each including shipping. They're a good all weather touring tire. See my previous post w/photo, mfg. link & F*Chat discount info:
http://www.ferrarichat.com/discus/messages/112/153882.html
I'm quite happy with them for daily driving. If I ever seriously track the car, I'll get 16" wheels with a high perf. tire. |

Frank,
1. In my opinion a car is never too old to worry about performance. With today's technology great strides have been taken in improving designs that were already good. I have a 30 year old sports car of another make that is a prime example. Although it is not a Ferrari it has benefitted from suspension upgrades and tires that are better constucted and with better rubber compounds that were not available then. This has improved the handling characteristics and in turn improves the driving experience especially when pushing the bubble (albeit limited in comparison with some exotics).
2. "Why not go with the TRX", For the reasons stated above. I'm not afraid to spend money but why buy a tire originally designed 20 odd years ago when I can buy a better performing tire for less than what they are asking for a TRX?
3. No track for this one though it would be fun to try.
Thanks for the input, DJ

Why not just use the TRX tires ? That's what I have on my BB512i and they're fine. Your car is too old to worry about performance anyway. You're not planning on tracking the old girl are you ? |

Somebody I work with also suggested using a tube but I think the flange and bead configuration is incompatible which might allow the tire to dismount though I am not exactly sure how or why. I have never seen a 390 rim without a tire on it. Can anyone elaborate?
Thanks, DJ |

You could do it by adding a tube, but it may still not be safe. |

The rims are Cromodora and stamped 7 1/2" X 14" and I have two nearly new 205/70 X 14 XWX 'Green X' Michelins on the back and was waffling about springing for 4 new in the lower profile/softer compound instead of going for another set of Michelins for the front.
Any comments on the rubber hardness and rain performance of the Michelins VS after-market tires and different profiles?. It rains alot around here.
Thanks for the help, DJ
Is there any market AT ALL out there for concours condition 390 rims? |

DJ. It was me.
I have the 7.5x14 rims. It lowered the car and made driving the back roads a blast. They were sumitomo's. I have gone back to the 205/70's (sumitomo) and they are fine. Pirelli makes them as well in the size. If you have the XWX then any manufacturer will be fine. If you have the trx....your outta luck |

DJParks,
Are your rims standard or metric?
If standard, then you can put other tires on it. I bought Sumitomo tires 205/70-14- HR from tirerack for $40/tire for mine. I eventually plan to upgrade to 16" wheels. The 225/60 14's will work also, but will make your car sit about .75 inches lower.
It seems like unless you are willing to pay for the Michelin's it is very difficult to find V-rated tires in 14 inch size.

Which brings another question, I am running 7.5" X 14" OEM rims on my '78, can I run tires other than Michelin tires on those.? I heard of somebody running 225/60 X 14's but not sure of what rim they were using. |

Thanks Harry, now that you mention it I seem to recall a discussion I had about bead configurations 20 years ago but must have forgotten.
I have a friend that wants to sell me his rims with new tires for a 'good' price but I hesitate because of questionable availability of tires in the future. I heard Avon makes a replacement for the Michelins but the prices are still pretty high.

They are not interchangeable, because the TRX system is a different standard with different rim shoulders. The conversion will not be safe (or even holding the air). |

Sorry in advance for bringing this up but I haven't been able to find the thread on this.
I did the metric to inches conversion on 390 mm wheels and came up with 15.354330". This says the metric rim is roughly 3 & 1/2 tenths of an inch larger in diameter than a 15" rim. Spread the difference over the entire diameter of the rim is it really impossible to safely put a 15" tire on a 390 mm rim? |
