Hi
What tire did a 1973 Corvette come with Radial or Bias Ply?

Tom73

Radial.

gbvette62

73 was the first year radials were installed on Corvettes (and most other GM cars too). The size at the tire was also increased, from the F70x15 bias ply used in 72, to GR70x15. The modern equivalent of the GR70x15 is P225/70R15.
