I recently bought a 78 Silver Anniversary edition.  It has Goodyear Eagle ST's on it.  They have a lot of tread and still look fantastic.  I am going to get new tires because these haven't been made in a long time.  It's better to be safe than sorry.  Is there a market for these tires?  It seems as if someone could use them on a car that is used for shows, etc.

Were those ever an original equipment tire?  I put those on my 72 in 1997.

The Cooper Cobras are good tires for 15" rims.

Good Morning,  What is the date on the tires for manufacture? Do they have a "Blem" designation? What size are they? Do they show dry rot or UV deterioration? All these factors will determine the ability for use. 

Im not sure if they were ever original equipment.

I can't say for sure when these tires were manufactured.  These tires have no DOT codes so it was sometime prior to 2000.  That is when DOT started requiring that the dates be put on tires.  From the paperwork that came with the car it looks like they were purchased in 1992.  They have no dry rot and look excellent.  I don't know if they have any blem designation.  The size is 255/60/15.

Personally, they are not road worthy. Display use maybe. Recycle them, at least they'll get used. 

Yep, they are way too old to be on a car that is driven.  I don't think they are worth anything.

The original tires on a '78 were size P225/70R15.  The only GM authorized alternate tire was a P255/60R15 which were the Goodyear GT Radial with outline white letter tires, not the solid letter Eagle ST. 

What were the original tires?  They were white letter but I don't remember what tire.

Greetings, From my observation on photos, and stats, the 60s were only on the Pacer. The originals were possibly BF Goodrich TA. Not saying this is correct, but only seen in print form from publishers of Corvette Facts.
