Hi guys,

I get my new 525i Touring from the dealer tomorrow, but I need to know if the Dunlop SP01 DSST 17 inch tires that are on the car now are the ones that have the problem. This is a October 2004 factory production car.

I took pictures of the tires yesterday so I can examine them if I could just know the code number of the problem runflats. I heard the newer Dunlop DSSTs don't have any problems. The dealer already agreed to replace the tires with Bridgestone NON-runflats if I want after I showed him the BMW Service Report that I found on this forum, but many said the newer Dunlop Runflats are perfectly fine.

I found the numbers of the old problem tires once on this forum, but I searched here yesterday and again today and I cannot locate it. Someone had posted the old codes and the new codes printed on the outside of his replacement tires. Can someone find that for me, or do you have it bookmarked. I want to tell the dealer ASAP if I need to replace the tires.

Please help!

 

I searched for this for hours... apparently there is no set cutoff point for telling new codes apart from old codes. I actually called Dunlop to ask about my runflats because I was selling them, and they swore up and down that there was NO old and new style and that they wouldn't do jack until you actually brought them in with a problem. Perhaps there really was no old and new style, just bad batches.

I have been trying to find out when the good tires began to be produced. Does anyone know? And, does anyone know for sure how to figure when one's tires were made? My understanding is that the tires have dates on them.

From an earlier thread, I said:

"Do you know when your tires were made? Does anyone know when the improved version of the Dunlops was introduced? I have had trouble determining when mine were made--even though there is supposed to be a date on each tire. As best I can determine, mine were made in 1/05 and 5/05 (or maybe all in 5/05). That is, I find 1505 (or maybe it was 10505) on the fronts and 505 (or maybe it was 0505) on the rears. I purchased my car in 6/05. All help appreciated."

 

i,for one,do not think that dates of production of these runflat Dunlops have anything to do with noise and premature wearing.Although i dont like the ride of Dunlops,but i did not find them to be noisy or wearing out faster or unevenly on my car(production 6/04) and on friend's identical 545i sport(production 12/03)-we both have around 16k miles and have about 5k miles of thread left on rears and lots more on fronts.Just my opinion

 

You could be right. It could be only the code numbers mentioned above that seperate the goods from the bads. Still, there could/should be a close connection between the code numbers and the dates of manufacture.

 

Why worry about the codes now? Just drive on the tires and see if they become exessively noisy. If and when they do, get them replaced. You'll end up benefitting from the miles you drove on the noisy tires and you'll get a free set after racking up a bunch of miles on the old set.

It's not like there's a safety hazard or anything and at the price of these tires, it's a bargain you shouldn't pass up...

 

Its not so much the code on the tires or the build date of the car its the DATE on the tires that will determine if you have the new thread design and new compound.Call Dunlop and they will tell you if you have the NEW or OLD thread and compound,thats what I did to find out what I have. Make sure that you have the dates on all 4 tires if they are different to give to them.Good luck.
cheers

Rudy,

I am going in on Thursday for my fourth set of tires. Getting free ones is fine but what about after 50k? I am very concerened that I am going to be shelling out thousands of dollars every year for new tires. Do you know for sure if other brands of tires do not have this problem or is it the car and sport package that is causing the tire wear?

 

Well, I want to know because I am getting new wheels/tires. The "old" ones will sit around quite a bit; being used primarily on trips and perhaps at the end of the lives of my repacements. But, my dealer is very cooperative and would replace them without waiting for noise to develop if I can figure out if, theoretically, I have bad ones. I would rather take this approach than to introduce confusion by having vastly different miles on my car than on the run flats. Also, I would think anyone would want to know; knowledge increases options, flexibility, and the ability to accomplish desired things. I can think of a variety of scenarios where I could benefit from knowing what I have. But, I do agree with the general idea of why not rack up some miles on the "bad" tires. I would just prefer to do so knowing all the while what I have.

 

Yes, I have been asking about tire manufacture dates not the auto build date (see above). Calling Dunlop is a good idea. Still, I was hoping someone here would be able to provide the info. It looks like no. What dates were on your tires? And, as indicated above, I have been having some trouble identfying my tire manufacture dates. Do you know the form the dates take on the tires? Please see my earlier post.
