I vote for the 14th week of 2001.  Currently I believe the tire mfgs are calling for replacement every 6-8 years.

I'm going with 14th week of 2001.

I bought the car back from my best friend at the time, I think (????),  I put these tires on it then.

Maybe 3,000 miles on them. Really, 22years ago? Damn I'm getting old.

What size would be the replacement? I think these are one size too big, as they don't fit correctly in the spare tire tub. 

BFG RWL P225-70-15 are on the car and the spare.

I run 255-60/15s on mine. But I still have the original spare in the tub. It's never been on the ground.

Most any size should fit in the tub. They are quite large. I have 235x60 in mine. Just thread the rear bolts down a bit to make the tub hang down a tad more. 7 or 8 inch wheels should not matter.

225x70 15 was the stock size in 72.  I run 235x60 15 on my car and in my spare tub.  They are a little smaller in diameter than the 225x70.

Thats what I did - lowered the back bolts and it does fit, but a bit larger than the puny original bias tire. 

So yeah, the 225/70/15 was the correct replacement.

I agree with 14th week of 2001.

Regarding the spare in the tub... The one I had on my 1979 was trash, and my tire dealer could not  find the same type to replace it.  I searched and found a new unmounted tire online and it is:  195-R15C. (an 8 ply rating truck tire/says load Range 'D' in the inflation specifications).

Just in case it matters to anyone, the correct size for 72' was F70-15.

And '73 correct size is GR70-15. First year for radials. Interestingly enough, the recommended tire pressure was 20 psi.

I remember the F70 - 15 tires. Wide Ovals comes to mind. The spare in mine was untouched since car was assembled. Looked pathitic compared to the new P225/70/15's 

The tire store thought I was nuts ordering 5 tires. They screwed that up and only got 4, so I had to go back for the "full size spare". Haha
