Re: [Chrysler300] Cooker Radial





Sorry - on travel. Response to question of 20154 vintage American Classic DOY code CY is Mccreary Tire Co, Indiana, PA, USA - date code 1514 is 15th week of 2014. 

If I remember correctly HU is internal size coding and I dont know of any source to decode L2FL

Hi Ed,

I  bought American Classic P235/75R14 tires in 2015 from a vendor at the Macungie meet.

The DOT code on the tires is CYHUL2FL1514.

I am satisfied with the tires and have not had any trouble, but I haven’t put many miles on them.

Carlton

If you can provide the DOT code, the first 2 letters identify the plant location. The 2002 vintage Coker Classic P235/75R14 narrow whitewall I have has a code

DOT 4FF2 VLX 1902 (which translates to Cia Hulera Tornel, Mexico)


2016 vintage Cooper Trendsetter SE P235/75R15 code as follows:

DOT R7HL C2T 2216 (Corporacion de Occidente, S.A. de C.V., Mexico)



Would like DOT code off any recent production American Classic

Thanks, Ed

More fuel for the long standing Coker/radial debate:

 

For what it is worth, the American Classic branded Coker tires are made in the USA – I think in PA.  I do not know if they are from clamshell molds.  I have two sets since 2012.  One is a 235/75/R14 on my ’57 New Yorker and one is a 235/75R15 on my Imperial.  Both have performed well.  They do require more weights than typical – the manufacturer alleges this is because of the wide whitewall.  Could be BS; I do not know. 

 

The 235/75/R14 was very expensive.  Imagine that.  There isn’t any other choice in a 235/14 radial 2&1/2” whitewall (or least wasn’t a few years ago).  I have driven them at up to 75 mph with no issues.  Just my 2c  Your mileage may vary.

There seems to be quite a gap in quality between Coker branded and American Classic (bought from Coker) . I have 4-5 of the latter sets,  14” but do not drive them that much..but so far no problems. JY told me he had the same experience, I followed his advice, and this post just confirms it yet again  . Those who have trouble with Coker branded 14” are not alone. I am a big fan of Michelin, but it drives you to black walls. . Once you can deal with that, modern lower profile 16 “ , like on JEEP Grand Cherokee , come into play too. I have used Cragar aftermarket black steel wheels with those.  

 

The point about balance is important too…many Michelin  sets need no weights at all. Just made right. That impresses me. no more shaking at 72.

 

At one time there was a vendor who welded rings into 15” wheels such that 14” 300F wheel covers would fit. I agree that is the best solution,15” wheels, if you really want to drive the cars harder than show cars, and get better tire technology .

I think those of using 14 inch wheels on older Chrysler, Dodge, Mercury, Pontiac, Oldsmobile, etc. are pretty much out of luck.

Last Production tires in the 235/75R14 and 225/75R14 were made by Cooper and their related brands such as Mastercraft, Multi-Mile, etc around 2005. The only current option in 235/75R14 (replaces 8.85-14 or 9.00-14 or 9.50-14) that I know of is American Classic sold by Coker as well as others.

And as you note, several people have had problems from separation to out of round / major balance problems with the low volume specialty radial tires in these sizes.

An argument against such low volume specialty production tires as well as the bias reproduction tires is that these are very old technology and not generally subjected to the same level of quality control as high volume production tires. Most if not all of these still use the old clam shell molds.

This may be less of an issue in bias tires, but when early bias belted tires were introduced around 1968, Goodyear had done their homework and invested in technology while the other of the big 5 Tire makers (Firestone, Goodrich, General, and Uniroyal) and the private brands rushed to catch up. The same was true for Radials - Michelin had introduced them to the US in the mid 60's and Goodrich followed in 1966. The other of the big 5 were still focused on Bias Belted and had to rush radials into production in the late 60s and early 70s.

As a result there were many recalls and radial tire designs were iterated multiple times. One of the more significant improvements was going from the old clam shell tire molds to the segmented molds which better accommodated the steel belts. As I said, unfortunately most of the low production specialty tires are still made in the older style clamshell molds. Furthermore, they are generally made in small batches and do not benefit from continuous production - this tends to further aggravate consistency in product compared to tires which are mass produced.

A Coker Classic 235/75R14 I have with a 2001 production date has never seen the ground. It was made in Mexico in a clamshell mold. Further it is very heavy compared to any one of 4 brands of mass production 235/75R15. I have never dealt with American Classic - they look similar, but again I have no example to evaluate - they may be superior, but having lived thru the 60's and 70s with direct contact to radial tires at that time, I would not personally want a clamshell made steel belted radial. You can tell if its a clamshell mold - there is a visible splitline in a new tire with excess rubber flashing running circumferentially as opposed to multiple split lines running transverse to the tread.

The biggest production grade tires are 215/75R14 (26.7 inch OD - replaces 8.00-14, 8.25-14 - 27.5 to 27.7 OD) available in narrow whitewall. They probably have load capacity to replace 8.50-14 (28.1 to 28.4 OD) but will be significantly lower diameter and of course radials squat more than older bias ply tires. If you choose this option, I would make sure I stayed away from the multiple lines of Chinese made tires that come and go under different names. I have gone with Hankook H724 where the 215/75R14 was appropriate.

But I think the best option is to switch to 15 inch wheels if possible. Here you have the option of 225/75R15 which is a good match for 8.50-14 diameter or 235/75R15 for 9.00-14. And depending on size, Hankook, Nexen, Toyo, Maxxis and Cooper have these available in narrow whitewall in tires produced in Indonesia, Korea, Japan, Taiwan, and Mexico respectively. The last Cooper I have with a date code of mid 2016 was still made in clamshell mold in Mexico. And if you want to go Diamondback there are many other blackwalls in these sizes.

In preparation for the spring meet, need to replace the old 900x14 bias ply tires with a radial.

 

Diamond Back is still in process with their 235/75R14 and no info available for when the long of tooth project will happen.

 

I purchased a set of the Coker radials back in 2001 and after 3 had separated (not good!) within few months of purchase they swapped out for the 9:00x14, too their credit no charge for tires or shipping.

 

Would appreciate any feedback from members on the radial tire subject 

 

    Thanks to all.
