The earliest Sebrings had 16-inch wheels, like the 3500GT it was derived from, for which a 185VR16 would be the best fitment today. 15-inch wheels were introduced with the Series II in 1965, fitted with a 205R15 radial tyre.
A 2+2 coupe derived from the 3500GT, the Sebring was aimed at US customers. Handsome, and with good performance, it was developed through 2 versions until the end of production.
