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



Interpreting side wall cracks correctly is for sure a big mystery, Better if not there, but if a cause of failures,  there would be a widespread recall??? I have had two sidewall failures at speed,  properly inflated tires, Firestone and Kuhmo. (sp?) ; the sidewalls looked ok, no noticeable cracking. The failures were along the tire curve / circumference direction, not radially outward ( cracks can sometimes seem to be radial?) . I have never had a failure of any kind in Michelins going back to when Sears sold them..First set I bought was on a new 68 charger after one year. I bought it because of the steel belted construction. Are they still steel?? , I do not know. Did not like the narrow tread look then, on Charger,  compared to the wide oval then in vogue , but OEM tires on Charger were 15-20k items. Michelin went twice that at least, I was driving a lot in my job then, on highways. . I agree,  sidewall cracks disturbing to see. One would , however, expect tire guys ( Michelin dealer) to know the issue. Maybe it is outer “good looking” skin, many  more inner plies? They cannot tell you it is ok , if a known malady, and then have a failure? Huge liability. I do not know enough to say anything concrete on this. But I have had maybe 20 sets of Michelins with no issues . None. 

 

I believe that general lack of weights , and long life,  show excellent quality control / excellent conceptual engineering/ good materials. Why they command a premium. Conversely I got barely 15k out of Goodyear Eagles on 300CD Mercedes; lots of talk about “misalignment”, led to two replacement sets , two alignments ( Mercedes does not sell you misaligned cars , =my .02. ) . same deal, the two more sets, partial warrantee ,  wore out. Edges took on scalloped appearance, why I believed misalignment at first. .Did not change alignment, put on Michelins, 3X the life. No scalloping . That made decision easy going ahead.

 

Insert a quarter on sidewall crack  is clearly a totally dumb statement. Plenty of those around. They do judge tread wear with features on coins somehow.

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 Amazon.com 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

I have a set of 10 year old Coopers with less than 4K miles on them on my H.

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?

Thanks,

Doug Warrener
