I should've been a little bit more clear than mud. 

I'm just curious as to what the size tire he was running back in the 1960's. Can anyone translate the 5.50-9.20-15 into today's sizing.

FYI - I'm going with the 185-65-15

To determine the size of the old tire in modern designation format measure t=
he tread width in millimeters, I=E2=80=99m guessing 5.5 inches times 25.4 =3D=
 140, that=E2=80=99s your first number.

I=E2=80=99m guessing 9.20 is the dimension in inches of the top side wall + T=
he bottom side wall. When added to the 15 inch wheel diameter it would give y=
ou a tire diameter of 24.20 inches. This is just a guess of what they mean b=
y 9.20.

Next, Measure the side wall height in millimeters, I=E2=80=99m guessing 9.20=
 inches/2 x 25.4 =3D 117mm. Divide 117 sidewall height by the 140 tread widt=
h gives you a height to width ratio of 1.20 which is your second number... b=
ut they don=E2=80=99t show the decimal so it reads as 120.

So the old 5.50-9.20-15 =3D a new 140-120-15 (if my guess of what 9.20 means=
 is correct, if not, just measure the sidewall as my 120 number would be wro=
ng).

It appears that the old tire is 1.7 inches narrower than your new 185-65-15 a=
nd there is only 1/10 of an inch difference in the tire height.

 Todd,Back in the day I could never get the 9.15's under the rear fenders. =
I ran 5.00x8.30x15 on my car. I ran the "W" part number which was not catal=
oged and you had to order them specifically (they were about 1/2" wider - h=
ence the W suffix). Do not know if the 9.15's were available as a W tire so=
 you may need to compare yours to others to determine any actual sizing.Any=
way, I just compared a 5.00x8.30x15W to Yokohamas and Hoosiers. The Goodyea=
r was almost as large as a Yoko A008 or Yoko Ao48's. Probably just a bit sh=
orter than either of the 205x60x15 Yokos. The Hoosier Speedsters are a smid=
ge smaller and are about a perfect match for my 5.00x8.30x15W tires.=C2=A0Y=
our Goodyear's are a bit bit larger than mine so the Yokohama Advan AO52's =
205x60x15's would be about a perfect match.
Other tires may be slightly different but the comparable size would be 205x=
60x15. If you want to go to a 50 series tire, will have to check actual mea=
surements...can't help you with those.
I'm tired...Nick of Nor Cal

Thanks
