I have these BF Goodrich FR-60-15 T/A radials that look like Polyglass tires....Does anyone know then they were made or if they are still available ?

Look at the pix, the "RADIALS T/A" is in very small lettering and the B.F. has the periods between the letters, it also says SILVERTOWN on them, maybe the series.

I would like to buy one more for a spare if possible.

All tires have a DOT manufacture date.

First locate the letters "DOT" on the sidewall of the tire. Nearby will be the DOT code. DOT codes are 10 to 12 digits long. BTW the digits can be numbers or letters.

The first 2 digits are a code for the manufacturing plant.

The next 2 digits are a code for the tire size.

The next 3 or 4 digits are a code for the type of tire.

The last 3 or 4 digits are the date code. The format is week/week/year/year or week/week/year. These are always numbers.

Starting in the year 2000, the date coding used was 4 digits. That means the largest number you should see for the year is 09. Before 1999 the format was 3 digits. 1999 and 2000 are transition years, so you will find both 3 and 4 digits.

The date code only has to be on one side – and it is permissible for there to be a partial DOT code, so long as one side has the complete code.

Judging by the font of the white letters, they look to be 1970s vintage.

Had a 70' Mach 1 parked in my driveway for a friend who purchased it from a second owner that had bought it in 75'. Had what appear to be the same BF's on it and the last time the car was on the road was 82'. I took notice as i have BF's and thought they looked cool.

70's T/A's for sure

Buddy of mine had a set of GR60-15's on some aluminum slots on his 1972 Chevelle SS. Medium metallic blue with a black vinyl top. I remember it well. 1975. Killer tires for the day.

This was also posted in the "street forum"

Here's a few more pix of the numbers....they do not have the current style week/year code you find on newer tires, that was the first thing I looked for.

..also after the D.O.T. in has the same 145 # on all the tires.

I think these have a nice cool factor so I'm going to temporarily mount them on my Honeycomb rims just to take some pix and do some cruisin, I don't think I'd trust 35 year old tires out on the highway though.



Just a note, in the first pic, the second set of #'s (to the right) differ from tire to tire so these must be the "build" code ?
...or these ? ..the last pic (far right) with the plate # the first letter/number are different from tire to tire.

I am thinking Feb 1979 from what I see.
