Surely you're not serious ? Did you read the preceding post?
I just skimmed it.. Lots of talk about wheels, tires, spacers.. So I guess thats a no go eh?
Correct, I've highlighted why Michelin made the tires in an odd size, so they could only fit wheels with the special bead design, unique to the TRX
Remember why Michelin 'invented' TRX. Their tires became industry standard for long wear but goodness they gave a harsh ride and if car was not designed for them it was harsh on the rest of suspension. So the 45 degree bead was their attempt for a nice ride and still have long wear. They had to go metric sizes because they feared tire shops putting a 90 degree bead tire on a TRX rim or vice versa. Tires would fall off the rims!
That makes sense.. I have two sets of Metric rims. I will post on ebay soon. They are so damn pretty. Its a shame......
Hopefully someone olse maybe a purist will see the value in them...
I think the suggested harshness of ride was due to the fact that they were replacing considerably taller tyres. Before the TRX anything lower than a 70% profile tyre was outstanding and the Ferrari 400 was now running on 240/55VR415 Michelin TRX where initiallyit fitted 215/70VR15 Michelin XWX so it has lost nearly an inch in sidewall hieght, which is where the comfort comes from. Michelin counteracted this in some part with the clever rim profile, but what it did give them was the ability to put considerably more rubber in contact with the road and the lower side walls improved the ditrectional stability on cars like the 400 that were set up to suit them.
The good news is that most of the Michelin TRX Tyres are available again. Added to the fact you are keeping your car original you are running on Michelins. they are always top price tyres because of their quality. the directional stability is remarkable, the longevity is excellent, and they look great. The ones at Longstone now have a 2013 date code.
Has anyone that replaced their OEM metric wheels looked into having the stock wheels refinished first, or later? I'm ready for that step and looking for a west coast service provider.
I looked into it a few years ago and found some suppliers through the other forums here but also many horror stories. I was a little freaked out that you do not know if they did a good job until a few years pass without any bubbling under the finish. So, I drive on Superformance 16's and my oem 15's sit in a corner silently corroding while I hope to hear of a reliable refinisher.
p.s. I have a set of 415's to sell!

Hold on- will testarossa wheels (tears are 10" wide) fit on a 400i? That would be amazing
If you put testarossa suspension in it. And maybe a mini tub kit from summit racing.
We have some interesting 16" Pirelli P7 tyres now https://www.longstonetyres.co.uk/pirelli-collezione/cinturato-p7.html However i think they are too small in diameter for you guys
Roll around wheels?
Does anything readily available and cheap bolt on and the clear brakes? 108mm bolt circle is essentially 4 1/4", a common Ford pattern.
Just to roll around while the TRXs are being refurbished.
Good luck selling one or two sets of TRX wheels on ebay or anywhere else. There are hundreds of them in back of garages. I sold my set to an antique dealer that planned to make 'man cave' glass top tables with them!
I'd buy a set if I could find them.
The TRX tyres are easy to get if you want them https://www.longstonetyres.co.uk/classic-car-tyres/ferrari/400.html
