If anybody is looking for some, this guy has several options available. They don't come up for sale very often. Ferrari 365GTB 4 Daytona BB512 Cromodora 9x15" Rear Wheel 109193 Pair | eBay
Bf Goodrich T/A - 235R60x15 on front and 255R60x15 on rear. Good for touring, but not tracking or high speed.
Are you sure 345?35 ? That would be dangerous and look way off on only a 9 inch wide wheel. A 345 tire should have a 12inch wide wheel IMHO.
I´m sure so it stands in the paper from the german TUEV / technical controll. but I will look tomorrow what is standing on the rims
The only tires I see in 345/35 15 are Pirelli P Zeros and recommended rim width is 11.5"-13". Those things are $750 each.
I am now curious to see some of 9 inch rear wheel combos with some fat tires. If anyone has some post some pics up please
