I have a great set of (4) Goodyear GSCs 255/45/17 & 285/40/17 that are coming off my 96 Vette Convertible tomorrow. They have about half their treadlife still left. The only reason I'm taking them off is their age at 12-14 years old. The previous owner must have found a NOS set and put them on a few years ago. What would they be worth and would anyone be interested? I have the option of keeping them or just leaving them at the tire shop. I have not set a price. The tread averages 4/32 - 5/32. The date codes are front 397 & 476 the rears are 288 & 466. I'm located in Palm Harbor, FL. Thanks
