Location: Ramona, CA | I just put these 235 70R 15 Cooper tires on my 1960 Chrysler wagon. I haven't driven it yet but it looks like they'll be fine. I need to pull the old 9.00x14 spare out to see how the height compares.

Location: So. Cal | That's a nice size for the big cars. I'm running whitewall versions with the same size on my '60 New Yorker. |

Location: Springfield, MO | I recently did this exact thing for my 1959 NY. I lucked out and got a new set of 225/70r14 with rims and hubcaps from a Cordoba from a man in the local car club that switched to alloys to replace the 14 rims I had. They are still small in diameter by 1 inch to spec, but the PO put 205/75r14 about 20 years ago and they looked dinky compared to what I have now.
Per Coker Tire BF Goodrich's 9x14 are 28.68 dia and 9 wide.
IMO the 225/75r15 is the closest you can get radial wise to the OE Tire specs. 8.9x28.3
A 235/75r15 will get you 9.3x28.9, which is still within a mile or two error on the speedometer.
I looked up the 9.00x14 bias tire specs from Coker Tire and used a tire size visualization tool online (I used tiresize.com) to find a modern size closest to the 9x14 OG in a 15 inch rim. Closest you can get that doesn't cost an arm and a leg in 14 inch is a 215/75r14 (8.5x27.7), but hardly anyone keeps these in stock and will have a a or two to be ordered. This is mostly used for trailers.
If you have aftermarket alloy rims I think your backspacing needs to be considered, which you would have to go to talk to a rim shop and take some measurements. I took some Coys 275/40zr20 and 245/45zr18 off of my Chrysler as well and removed the lowering blocks on the rear. with this setup, the 18 rims would rub the fender in tight turns and the rear wheels had to be removed from a lift and could not be removed by a jack.

I am pretty sure those are like hens teeth in the US. Just Like finding a 235/75r14. If a tire shop can get it, they would have to custom order them. Your size doesn't look bad, but your speedometer would be off because they are still off by a little over an inch in diameter at 27.5. |
