That could certainly be it. But I've had my combo of worn front + new rears before & vice versa (albeit they were all Michelin models before this):
1. new Primacy tires front & rear (stock)
2. Worn front Primacy tires + new A/S 3 rears
3. New A/S 3 fronts + Worn A/S 3 rears
4. Worn A/S 3 fronts + New A/S 3 rears

And within the past 1,500 miles:
5. Worn A/S 3 fronts + new DWS 06 rears
6. (current setup) new DWS 06 fronts + Worn A/S 3 rears

All sizes 225/45/17, except of course for the stock Primacy tires. All kept to stock psi of 35.

#5 is the ONLY combo that causes the traction control to blip over rough/broken pavement.

Could something be wrong with the individual tires such as a quality control issue?

I've driven a quarter of a million miles on the DWS and DWS 06 on several different cars, and they've consistently performed spectacularly for normal and spirited road driving. I'm currently on the A/S 3+, which I think is an advancement in dry (inferior in snow), but not one that is night-and-day IMO.

Yep, seems like it's just the rear tires that are affecting the nannies.

I moved the DWS 06 to the front, and put my worn A/S 3 (40K+ miles on them) to the rear = no more nannies! I even try to accelerate through those broken/rough patches on the road to see how the A/S 3 (in the rear) would react = still no nannies lol


For anyone in Atlanta, there's an off ramp on GA-400 (southbound) that curves in a half-circle with a TON of rough/broken pavement. It's the exit ramp to Glenridge Connector. I've taken this exit ramp several times at normal speeds with the DWS 06 on the rear (the past 1,200 miles), and EVERY SINGLE TIME the nannies kick in. I have to slow down A LOT more to keep the nannies at bay. I'm talking slow like a big moving/delivery truck kind of slow.

I've taken this exit at a HIGHER speed with my worn out A/S 3 tires in the rear (when I'm by myself of course), and the traction control never kicks in!

I'm not ruling that out as a possibility.

Again, the DWS 06 performs just fine over normal roads, there's no night-n-day difference like you said. It actually felt a bit more comfortable than the A/S 3. It's only over broken/rough pavement that this is an issue.

And by broken/rough, I mean the road looks like a contruction vehicle dragged its huge digging arm over the pavement a few times.

Have you pulled the tires off and measured the circumference? I'd get ahold of Conti's customer service and see what they sway.

No, I'd rather just sell the tires for $80 a piece if I can and be done with them. I don't expect much, if anything useful, from a customer service rep.

I'd rather ride around on almost bald A/S 3 tires at this point.
O wait, I'm already doing that!

If I recall what I've read in the past correct, it has. But a better question would be - how on earth would a set of highly rated tires otherwise cause this behavior? If it's not the circumference of the tires causing it, then it's not the tires causing it in the first place. That is, unless OP isn't actually driving along at a steady state as he described. It's a pretty simple list of things that triggers nannies.

It is not the diameter. Many guys run different diameter tires when going staggered without any issue. I have. Also, when the nannies were turning on, I was gong 45 around a corner I can take much faster normally. (55 Miles an hour, not trying to break any laws )




I have had approx. 50 tires on my car.

Then explain exactly what the tire does to trigger the nannies when OP is travelling at a steady rate, in a straight line? "Crappy tire" is not an acceptable answer for a whole host of reasons.

I was referring to side to side diameter when I asked him if he measured it. Highly unlikely that it would be off, but I have seen some weird shit in 10 years working directly with tire manufactures.

I don't think the OP is interested in finding the cause. I think he is just venting about his bad experience with these tires.

I'm driving at a steady pace at or below the posted speed limit with the DWS 06 on the rears.. and the nannies still kick in. With the A/S 3 (new tires or 40K worn tires), I can drive faster over that same rough patch (on a curve or straight) without the nannies interrupting me.

Again, what I'm experiencing with the nannies DOES NOT happen on a normal paved road. It doesn't even happen on a paved road with small visible cracks in it.

I'm talking about broken pavement or very rough pavement, like a contruction digger attempted to scrape the top of the road off or something (attempted, but not actually succeeding at it). So yes, the road may be "good" enough to drive on technically (which is probably why it's not been fixed or repaved), but it's horribly coarse and rough when driving over it.. especially in a sports car.

This is probably NOT something most people will drive through on a daily basis. Unfortunately on the Atlanta highways, its common to encounter this.. depending on your commute.

So no, I don't expect Continental to do anything about my city not wanting to repave its broken pavements. I highly doubt any manufacturer tests their tires on this type of broken roadway either. I'm simply warning people that if their commute has this type of broken/rough pavement, to avoid these tires.

And also because the city takes forever to fix broken pavements & potholes!

But kudos to Michelin for making tires that can handle this type of crappy pavement

So just to be clear, you're saying that these tires are so incredibly incapable of maintaining traction when going over rough roads (and trust me, Atlanta highways are in no worse shape than roads in any other area of the world that receives poor weather) while maintaining a constant, road-legal speed, that they cause the TC nannies to intervene?

Given that you don't have a complete set of new tires, plus the well deserved reputation and ratings Continental has as premier tire manufacturer, plus my own positive personal experiences with Continental products, I feel safe saying something stinks in Denmark.

Yes, that's exactly what I'm saying. I don't know what other roads are like in other parts of the world, so I can't comment on that.

By "rough" and "broken" I mean:
Visible grooves in the road, or broken portions of the top pavement, causing uneveness in the level of road, enough to cause one side or both sides of the car to actually 'dip' slightly & roughly while going over these portions of the road.

Keep in mind this is on the highway & highway ramps, not small roads. Speed limit is 55-70mph depending on which stretch of the highway you're at (so "normal" flow of traffic speed can be 5-10 mph above that). At this speed, the car can jolt quite a bit depending on how big of a groove or broken pavement you went over. On the curved ramps, I'm usually doing 40-50mph depending on how sharp the curve is.

Again, there's no problem with the nannies when the DWS 06 are in the front. Only when they're in the rear do they cause the nannies to light up over rough/broken stretch of the roadway.
