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?

You should expect high-performance tires to wear and, thus, to get somewhat noisey fairly quickly. You could always buy good, but less performance-oriented tires.

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

I don't know who you spoke with at Dunlop, but the guy I talked to refused to admit there are 'old' and 'new' versions of this tire at all, and wouldn't budge.

What were the dates on your tires? How are the dates coded on the Dunlops?

Here is what I have come up with:
I too am experiencing loud tire noise and would like to know if I qualify for the tire replacement. As explained in technical service bulletin: SI B36 02 05.

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!

Thanks, BMW 545i Titanium Silver, for the date information. What I found was very interesting. First, I have a very quiet set of Dunlops. The dates on them are:

Left side-Air freighted from Dunlop distributor in Chicago.
4103
1303

Right side replaced by two wheels & tires from a dealer demo w/300 mi
0704
2004

They appear to be wearing evenly and everything is copacetic at this point. Go Dunlop! Rah, Rah!!
