How do I know what size the wheels are on my 1964 Ford Falcon Sedan?
Is there a number on the wheel that’s easily found without removing tires or
wheel off the car? I have a 1964 Falcon Sedan, 6 Cyl. 170 straight, 3 speed
Manual Transmission, and Manual Brakes. The original manual lists the
different Falcon models and engine sizes and for my model, wheels are listed
as “Std.”, “13 x 4.0”, “R.P.O.”, “14 x 4.5”. What is “R.P.O.”? Since I only
want one wheel, it needs to be the same size as the other 3. I apologize for
asking so much.
Here’s a pic of info I spoke of in my questions:
Look for the tire/wheel diameter on the sidewalls.
The tire size is P185/70R13. I don’t know anything about confirming the wheel size or how that relates to the tire size, except the 13 is the same.
13" wheels are what you have. The width of the wheel is probably stamped on them somewhere or just have a tire shop measure them. They can also measure the offset.
RPO means Regular Production Option that were sold with the car when it was produced. So If I were you for better handling of the car go with the biggest tire that will fit and I would not change just one tire I would do at least two for better handling...I would go with the 6.45 x 14
I’ve been trying to replace parts that are original type, and so far can not find 13 x 4.0 wheels reproduced for 1964 Falcon sedans. It’s very frustrating. Do you think that’s bcuz car restorers found that the original size gave “bad” performance and so they didn’t make OEM or after market replacement wheels?
