I am restoring a 64 lemans conv. I need to put some cheap used tires on it just to get it around. On the existing tire sidewall is 7.75 x14. Can someone tell me what the equivalent modern size would be? what is the original tire size for 64 lemans conv.? thanks

 

I think that is to fit the wheel size 7.75 inches wide and 14 inches in diameter. Tire sizes were probably something like a H7814 which is really fairly small by today's standards but you could probably fit a 21570R14 on it. I think there is a conversion chart on the web as I recall seeing it one time. I know 78 series are next to impossible to find now but if you could those would be closer to original.

 

That is equal to a 195R14.

* When replacing Alpha Numeric tires with Euro-metric or P-metric tires, look for the Euro-metric or P-metric size listed in the equivalent aspect ratio. For example, when replacing a FR78-14, you would look up the appropriate 75-series size, the 205/75R14. If replacing a FR70-14, you would look up the appropriate 70-series size, the 215/70R14. If replacing a FR60-14, you would look up the appropriate 60-series size, the 235/60R14.

Disregard that mass of tire sizes, the chart did not come right.

thanks everyone

 

F78X14 was the size it came with.
