I saw all 4 tires on a 2004 Volvo C70 mostly driven in NYC with bubbles on every tire, both sidewalls. The car had around 20-25K miles. They, indeed were low profile tires, as you pointed out, but I do not recall the brand. There was at least 40% tread life on those tires. It was the first and last time I saw anything like that. These were GFT's.

So here's the deal my the runflats on my 330i:
 
1. I haven't inspected the INSIDE sidewalls, so don't know what's going on there.
 
2. Spoke with the nearby BMW dealership and they tell me bubbles are likely impact damage and, in all events, the tires are not covered by the BMW warranty, and instead I need to talk to Bridgestone.
 
3. Spoke with BMW corporate and they tell me that I need to talk with Bridgestone.
 
4. Spoke with Bridgestone and they said only 1% of tires are defective and that therefore my bubbles are cause by either impact damage (curbs, potholes, etc.) or mounting damage. They said I would have to take the car to a Bridgestone dealer and have the tires removed and inspected, but most likely they would determine that they are not covered by a warranty.
 
This strikes me as ridiculous. I have four tires with bubbles. My coworkers who drive the same roads do not have damaged tires. Obviously something is wrong with these tires.
 
Has anyone been successful in dealing with a situation like this?

IMO, its probably not worth your time/stress...replace with Continental SSR's. These are good tires I have 10K on them now and they are quiet, handle better than the BS and wearing very well and even. $146 at Tirerack.com.

The 330i that milesontime has the problems with has the Sport Package, and I don't believe that Continental has a low profile RFT that fits the rear wheels of that car.

Well, as you and anybody who's even partially followed this discussion for a while knows (I assume that milesontime is a relatively new member which is why I'm making this post), I would suggest that milesontime buy four new GFTs and a can of Spare Tire in a Can or the Continental ContiComfortKit.

I don't know if this is a solution that is acceptable for our new member, but there it is.

I'm not a fan of the Bridgestone RFT, as some will know from previous posts, but I do come to the defence of the need to check if it is 'impact' damage. Having spent time with a Bridgestone engineer, it is clear that many users run the tyres 'low' on pressure, to try and improve the ride quality. This is a main cause of premature wear and also can contribute to impact/pinch damage. So it can be common for more than one tyre to be damaged on a particular vehicle. What pressures are you running?

BMW is replacing defective bridgestone EL42 RFT's no charge for tires with less than 10k miles..50/50 split 10k-20k. It cost me $350 for 4 new EL42s..
 
Keep screaming at the dealership, keep calling BMW corporate to complain and file a complaint with you State Attorneys General, consumer afairs fraud division..make noise it helps

In this case I'm highly skeptical that it will help. The fact of the matter is that milesontime does NOT have the defective EL42s. The other fact is that low profile tires are far more susceptible to road damage than the touring tires you have on your car, BMW even says so in all of their sales literature. More or less their warnings say that by buying the SP, you will get better handling at the expense of being far more vulnerable to tire and wheel damage from road hazards.
 
If, and I need to stress if, there are signs that these tires were damaged due to road hazards, and/or low inflation pressures, there is no way BMW or Bridgestone should be on the hook for new tires. You pays your money, you takes your chance.
 
The flip side of course is that IF both the inside AND the outside sidewalls are blistered (if it's just the outside sidewall, then that indicates encounters with curbs and such), AND IF the inside blisters aren't directly across from from an outside blister (which would indicate an encounter with a pot-hole or other road hazard), then anybody would have a very difficult time convincing me that these tires aren't defective.

These may indeed be impact bubbles.
 
On past cars I've owned, I've had situations where large potholes caused bubbles on two tires at once, especially on those with low profile tires. I don't know if you hit a lot of potholes, but it very well could be impact damage and not defective tires.
 
That said, I think these tires are crap, but the complaints that I've been hearing on these are related to premature tread wear.
