4.5" vs 5.5"
I think the official story says original wheels for a '66 1800s were 4.5". Other sources mention 5.5" as period sport options. So, what would you choose for an as close as original but not talibanesque restoration?
Aesthetically I do not love the original 4.5"-165/80 combo, but a 5.5"-185/xx seems too 21st century to me. What about a 4.5"-185/70? It does a very similar wheel diameter. Will anybody share a picture of 4.5" wheels with tyres other than 165/80?

Thanks a lot!
Do anybody know the ET/Offset of each measures?

Just some observations
- 185/70 15 is a size with exceedingly limited availability. You have Vredestein (expensive) and Pirelli (very expensive) and there used to be some off-brand Chinese tires which now seem hard to find. You might want to consider a tire that is more common with a more reasonable price - 5.5" rim width is the recommended size for the 185 cross section with 4.5" being the absolute recommended minimum. The shape of a 185 on a 4.5" rim will change from the optimum with a higher profile and scrunched tread width. "but a 5.5"-185/xx seems too 21st century to me" I think you got lost in a time warp! 5.5" - 185/70 is pretty solidly in the mid 1970s. Since the turn of the century Honda Civics and most other compact cars have been running 195 - 205 tire widths. In the 1990s 185/65 was very common and was still in use on a lot of the base model versions of cars like the Civic after the turn of the century. 185/65r15 tires have a relatively wide selection; but, you will have to deal with the reduced diameter. |

Here are some 175/60 section tyres fitted to the later type 4.5" wheels:
... they are M&S tyres that I use in the winter, they also make the speedometer read spot on with a Type D overdrive and the original 4.1:1 back axle. I think they look pretty sporty on the Amazon: ... they work really well, the steering seems a little lighter than with 185/80 tyres in the standard wheels (that I use in the summer):
