Re: [Chrysler300] 235/75R/15 Tires

Cooper makes tires under multiple names.

This was not uncommon in old days - Goodrich made Hood, Brunswick, Miller, Gulf, and more - generally high quality products warrantied by named companies not Goodrich. Same for all the big 5 (Goodrich, Goodyear, Firestone, General, Uniroyal) in the 1960's.

But Cooper seems to have expanded the practice - I am pretty sure they make tires distributed by TBC, Treadways, and maybe others - in some cases, they may make certain lines and someone else makes other lines within same brand. Again look for plant codes and it will tell you who / where made.

Among others, I believe some or all  Multi-Mile, Mastercraft, ElDorado, Cordovan, Sigma, Vanderbilt, Jetzon, Telstar, Tempra, Dean, Hercules, Starfire, Vanderbilt, Big-O, and some Sumitomo are made by Cooper or possibly for Cooper by Kenda or Avon or ???

As you say, some of these are sold by specific outlets only and the outlet would be your warranty avenue. I can not address quality or consistency of any of the side-lines as to possible use of cheaper materials or lesser quality standards, but ultimately the distributor (TBC, Treadways, etc.) should handle warranty if your dealer will not.

I would not expect Cooper to handle warranty on these side-lines, but if it says Cooper on the sidewall, they or any Cooper dealer should handle any warranty issues. As far as I know Cooper uses the side-lines rather than making unique Cooper-branded tires for sale at specific outlets.

Goodyear and General, on the other hand, appear to make Walmart specific sub-lines with Goodyear or General name - so maybe Cooper does too.

You mention original tires were 4 ply and replacements are 10 ply. I wonder if you got P275/65R16 by mistake instead of LT275/65R16. That would clearly be a potential wear as well as a safety / load capacity issue if you were putting on a 3/4 ton or 1 ton truck.

I need to add something to my previous post.
Be careful of tires bought from Tire Warehouse, Pep Boys and the like.
Many mfg. build to price for the types of outlets and the tires you buy from them are NOT available from a Dealer. The same is true of new car tires, they are often not the better tires the Dealers have.
I did have a bad set of Coopers from Discount Tire Warehouse off of ebay. They were 265/75 R16 4 ply. My son paid $728.00 for them and in 10K miles the front tires were chucking pieces of tread out. My Tire dealer said they were not available to him and were built cheaper for the discount places. The Cooper Rep could not help as they were discount tires. He did work with my dealer and I got a new pair installed for the wholesale price.
The new tires on the front are 10 ply and now wearing properly.
The ones on the rear are holding up but not gonna give me the mileage  I should get.

I believe Cooper still has 3 US plants, Findlay OH, Tupelo, MS, and Texarkana, AR, but I believe they also source some of their tires from China, India, and England - you have to look at first 2 characters of DOT code to see where made.

I don't know if India is still in the picture, but at one time there was a proposed merger or acquisition of/by the company they were affiliated with in India that fell thru. England is combined with Avon and China with Kenda.

Problem is availability of sizes for older cars. 14's rare as hens teeth, 15's going that way. 16 inch is kind of minimum in current OE use with 17, 18, 19, 20 more and more. And whitewalls even harder to find.

Older P225/75R14 Trendsetters I have were made in AR, but they were discontinued about 10 years back. Cooper internet site shows Trendsetter SE still made in P235/75R15 in narrow white but the Trendsetter is a low end tire (low priced tight margin) and I had heard these had been off shored to Chinese factory due to cost of manufacture - but if they are low production they may still be run in batches here like the old big 14's before they were discontinued.

Don't have any newer P235/75R15 to check, can anyone provide DOT code on recent Coopers? First 2 characters after DOT is plant code: U9 is Tupelo, MS; UP is Findlay OH; UT is Texarkana, AR; etc.

Being an old fart, this goes back decades.
Back in the day, the understanding was that Continental Tires had a hard compound to aid high mileage and Michelin's had a soft compound for the top 2/3's or so for traction and better road holding abilities and then went to a hard compound to keep you off the cords. Thus, you found the on economy imports such as VW and Michelin's on the more pricey brands.
My wife  insisted on Michelin's just for that reason. Then, she would inform me she needed new tires when they got so they didn't hold as well as she was used to. Looking at them, the tread was well worn, but had some use left to my eye, but you could tell the difference on the road.

I now live in a rural area with mostly gravel roads and use only Cooper Tires. I tried several brands out here and found  Cooper's did best.
What we run into is that when the tread gets low, we end up with a rock puncture.
I use 10 ply on my Ram and they hold up very well. I would get 40-50K miles  on my older trucks  with them. I just put a set of Grand Touring 5's on my T&C, replacing tires with 60K on them.

Note that Cooper's are USA made and I use them as the ones I get are usually made in Arkansas, so I am supporting my state economy.

Let me also add that tires made in the last 10-15 years will NOT last very long. I have a stack of mounted tires that have exploded  on the rims of my cars  in the shed. ALL of them are tires made in the 10 years before their demise, and ALL my old tires from before 2000 are still holding air.
I even have a pair of 4 foot tall Implement wheels with Goodyear 4.5 X 36" tires that must be 60+ years  on display in my driveway that still hold air and have few cracks on them.

Ray in Mena, AR., wondering where the comments on the meet are?

Were they relatively fresh date codes (not 3 or 4 year old stock)? I have not seen any problems surface that early, but I did have cracking problems on some 4 year old Michelin Hydroedge a few years back and have had multiple problems on Continental OE on F250 truck as well as Trailer and daughter's Nissan Altima.

All my problems about 3 to 4 years after Date of Manufacture. And dealers will not cover unless you replace with same Continentals and even then its prorated based on 5 year life so not much use. I actually had pieces of tread chunk out on both the Trailer and the F250 (both were LT tires) and Ford dealer service guy said they have had similar issues with Continentals - recommended I replace with Goodyear which I did - but that is another story - finally got Michelins and did not have any further problems.

Impression is they are adding too much solids (high silica content?) and it is decreasing long term flexibility / extension capabilities. So it may be unique or more problematic on a particular rubber formulation / tire model.

I have a couple friends that have bought aftermarket replacement Michelin tires based on thier good reputation in the past.  Both have been very disappointed that their sidewalls are cracking in very noticeable ways that is disturbing after only a year of use.  When they took them back to their Michelin dealers, they refused to replace them and said the cracks would have to open up large enough to be able to insert a quarter in them before they would replace them.  They maintained that the cracks didn't affect safety.  So I am a little uneasy going with Michelins even on my 1997 Chrysler Concorde as I was planning on doing soon.  Now I don't know what I will use.

Hi Ed,
I had a hard time twice with cooper tires; one new set in particular circa 2010 was the root cause of an elusive 60 + vibration that was chased for a year , thought to be hub and drum run out , balance etc . " tires are fine" Changed everything , eventually even spindles . ( diagnosed as "bent spindle"  ? in desperation . Tires were balanced ok , ran in the machine ok , but one day I noticed on my own (!) the front of car moving up and down slightly while driving very slow . Tires were out of round , (!!!!), all of them !!  but apparently can be still balanced ?? . Coopers were / used to be reasonable tires ( state police used them , might have been made in mass way back) but I think now just a brand name bought by someone in Asia . Beware . Check roundness if a dance starts . 
Just me --and I do not like the black wall look , but I stay Michelin now , for cars I drive , except "restored 300 " where look matters a lot . Michelins Worth every cent . Never had a problem ; usually need no weights .  Perfect tires . Outlast other tires 2x, ( especially Goodyear best high end.. Michelin literally go 3x Eagles )!so not such a bad deal !! Keeping tail intact is job 1 . Diamond back was supposed to add white walls  to Michelin carcass ? Rumored ? 
Did you find that physical tire size place on net ? Even Michelin does not tell you the detailed full physical sizes of their tires , drives me crazy . Only listed by cars they fit ---in their own data base .  Dumb . 
I too hear good things about Hankook and Nitto . Had ? Sp Kuhmo ? Side wall failure at speed ; Firestone too . Do not need this .

According to the Cooper Tire internet site, there are several sizes of the Trendsetter still made in whitewall, including the P235/75R15. You might check the site for a dealer near you or just have your dealer double check. Ditto the Mastercraft AS-IV and several other Trendsetter clones made by Cooper. Just make sure the date code is fresh as there are not that many whitewalls sold.

Having said that, a more direct answer to your question about the Hankook, I like them and have had no issues with them in the P215/75R14, P225/75R15 or P235/75R15 narrow whitewall sizes. The P235/75R15 Hankook Optimo H724 are also extra load (XL = 108S = 2183 lb) vs most others including the Cooper which are 105S = 2028 lb rating. At a given pressure, load ratings are same, but you can run the XL tires at higher pressure if needed.

The H724 are slightly taller but my recollection is the Coopers and Mastercrafts tend to run on the small side compared to older tire specifications. The P235/75R15 H724 shows at 28.9 in OD with 9.3 Section Width and 5.8 Tread Width on a 6.5 inch rim. The Cooper Trendsetter SE shows 28.65 in OD with 9.1 Section Width and 5.9 Tread Width on 6.5 inch rim.

Don't know how much of a hurry you are in, but best prices I have found are Discount Tire on eBay - they generally have a $50 to $100 rebate and free shipping around holidays, but even without sale, they are comparable to and cheaper than dealers. This assumes you can get mounted locally.

The Hankooks I have gotten from both Amazon and Discount Tire have been fresh - some made in Korea - others in Indonesia. Best price I have gotten (after rebate) is in $60-70 per tire range - or $80-85 without rebate.

I don't think you will go wrong either way just stay away from the Chinese made tires.

Best, Ed

Cooper no longer produces the "Trendsetter" narrow white wall in the 235/75R/15 size.
Hankook does - anyone had experience with them?
Any other suggestions?
