Re: [Chrysler300] p235/75r14 tires

I'd settle for either P225/75R14 or P235/75R14. The 225/75R14 is the correct replacement for 850-14 and the 235/75R14 for 900-14 but as you note radials set lower for 2 reasons - they are 75% aspect ratio while the original tires were 83% aspect ratio and in general radials sit lower due to their construction. Neither one will really look right. And oddly enough, even the bias replicas are slightly shorter than original Deluxe Silvertown spec.

Original 850-14 circa 1957-61 were 28.3-28.4 inch OD with a static loaded radius (distance from ground to axis of wheel) of 13.0-13.2 in. (Variation in tire brands / lines - 3 samples of data BFGoodrich and Firestone). Coker Goodrich Deluxe Silvertown 28.1 in OD (No SLR data)

Original 900-14 circa 1957-61 were 28.8-29.0 inch OD with a static loaded radius (distance from ground to axis of wheel) of 13.2-13.4 in. Coker Goodrich Deluxe Silvertown 28.68 in OD (No SLR data)

1985 Michelin X Spec - 225/75R14: 27.6 in OD; 12.1 in Static Loaded Radius
2006 Cooper Trendsetter SE 225/75R14: 27.05 in OD - no SLR data
2015 American Classic P235/75R14: 27.87 in OD - no SLR data

2013 Toyo Extensa / Firestone FR380 P235/75R15 (yes 15 inch): 28.9 in OD; 12.9 & 12.8 in Static Loaded Radius respectively - so one could infer corresponding 235/75R14 would at best be 12.3 in SLR or so.

Bottom line - even the P235/75R15 will sit about 1/10 inch to 1/4 inch lower than stock 850-14 and about 1/4 to 1/2 inch lower than a 900-14. Neither 14 will look right - both nearly an inch short - but difference is probably less than 1/4 inch between 225/75R14 and 235/75R14.

So as I said to start I would gladly take either over a 215/75R14 or the slightly smaller 225/70R14.

When you use radial tires compared to the bias plys, using the 225s will yield a tire height that will not replicate the original tires. I would want a 235 to come closer to the original ride height. Otherwise, those 225s make the cars look slammed like low riders - ugh!

For those of us looking for tires for our K"s, we need narrow whitewall 225/75/14 radials, not 235's. I've been keeping in touch with Diamondback over the past year. First our tires were going to be available this spring, but now they are scheduled for sometime in the fall. Ugh! I'm still planning to drive my K to the big PA meet, but slowly and with a new non-matching spare!

Gloria,

Would you please send an invitation to join our club to Bill Chapman of Diamond Back? His email address is bill@xxxxxxxxxxx. He would also like to join the forum so he can address us directly.

I just spoke to him and got an update of the situation. The political upheaval in Thailand of a year or so ago upset the arrangements Bill had in place to produce the 14" big tire. He says things have all calmed down again and his supplier producing in large quantities - just not the ones we want.

He says he will contact his rep over there today and try to get some news for us. What will help is that we are not alone in needing this size. There are Lincolns, Buicks, and Cadillacs out there sharing our problem.

I wouldn't give it much of a chance, but Bill says it's even "possible" he could have some tires for us yet this summer. In the meantime don't run your Cokers too fast on the expressway.

Has anybody talked to Diamondback lately or even heard anything more about that ~900 x 14" with ~ 2 1/4 " ww radial? tire that has been "in the works" for so long?

As far as I know that is correct - largest "production" tires are still P215/75R14 narrow whitewall.

Coker American Classics still the only option for my F? The Diamondbacks that were discussed here from time to time don't appear to have been produced?
