They are all textbook impact bubbles. That means hitting potholes. The first 2 must have broken a couple of your teeth when they happened.

They are not defective tires.

You got guts driving on them.

They are dangerous and are blowouts at any second X3. The one in the first picture ... OMG you got guts driving on that!!!

Get them replaced immediately. Do not pass GO. Do not collect $200.

...

"though they don't look quite as dangerous as a typical bubble."

:WTF:

 

that's what those pics look like to me...impact bubbles...

I would have car flat-bed immediately to get tires replaced no matter if warranty or not = those are BAD

 

I agree as well, those appear to be from impact. The odds of getting 3 bad tires on your car when virtually no one else has had this problem are so astronomically against you.

Wheel and tire package should take care of you on this, but as CB said, GET IT TO THE SHOP ASAP!

 

... and don't forget to "drive with care and buy Sinclair"


... lets hope the package he has is not limited "by claim" like most are ...

 

Thanks.. The car is going in today.
It is a slow ride to the dealer.

 

Those are absolutely from pothole impact. My first one on a long road trip last year made me really wish I had found a model with the spare...

You should also definitely get an alignment after you replace those tires.

I got one of those from a pot hole and replaced when i noticed it...after i finished the 300 mile drive home. Got lucky. I think too many of these cars are over inflated from the dealer. Remember the dash gauge reads lower than actually at the tire.

 

Remember the dash gauge reads higher than actually at the tire.

?? The sensor readings that are displayed in the DIC are not accurate?

 

There seems to be a few threads that have shown impact bubbles in the tires. My impact bubble happened when i was at 36 when cold, but it got up to 42 on a hard back road drive in the summer, that was when the impact happened from a pot hole. Since them I'm a fan of 34 on the DIC when cold. Feel free to tell me i'm doing it wrong, the car feels more composed now to me. It used to feel like the car would skate around when I hit bumps, now its better.

 

So many potholes. I've never had this issue and hope I never do. Hope it's covered under the warranty for you!

 

2 pounds makes no difference.

Use tour and you will reduce the chances of tire/wheel damage by a huge amount.

"With the '14s one guy trashed 3 tires and another trashed one on the potholes in MI. With the '15's zero tires were sacrificed by using tour mode."

:hidesbehindsofa:

 

Maybe, but i think if if i hit that pot hole with 2 pounds more then it may have blown out instead of the huge bubble. Considering how out in the woods i was, it may have been a day before a truck would have come along after the crash. I was in tour mode.
I feel safer with a little more compliance in the tires now.

 

It wouldn't be a bad idea to also inspect the wheel(s) for being bent or out-of-round after showing impact damage like that. Might even re-check the alignment too.

The TMPS system does not measure true air pressure but assumes that outside the tire is at one standard atmosphere. (i.e. Sea level at 15°C).

It is very accurate, if you accept the above limitations.

 

That would be a bummer, because the car's computers (at least the PCM) already know local atmospheric pressure so it would be a trivial matter for the TPMS system to reference it properly.

 

Never trust the TPMS numbers to be exact. Use radial tire gauge to see the actual pressure and measure it COLD in the morning before driving.
If you really want to be serious, use TWO radial tire gauges and average the result.

Please ignore this post if you are a member of the new england patriots or staff, since your car tire pressure can't ever be changing due to the Commisioner mandating that Ideal Gas Law is not inapplicable to anything inflated by the NE Patriots.

 

:signlol:

 

For all you guys comparing/complaining about TPM inaccuracies you must first understand how the system works; and when you do and then know when to make the comparison you will find they are accurate when comparing to an accurate gauge.

 

Serious post here. If the false alarms are driving you too crazy and you'd rather just go old school, you can take 4 TPMS sensors, sync them to the car, mount them up in a small wagon tire, air it up to appropriate pressure, and keep in in your spare tire well.

Obviously this means you are without TPMS so it's up to which is more annoying to you. False alarms or having to regularly check tires that don't well show visibly when they are low.

 

Thanks for the suggestion. I just use more air pressure that I prefer to prevent the false alarms. At 5400 feet thats doable. At 10,000 feet I'd have to do something like you suggested. I've seen guys at the track (wheel swaps) use a short 4 inch PVC tube, capped at both ends with 4 TPMS sensors mounted so the valve stems poke out. Pressurized the tube to what the TPMS system wants and it will always think all 4 tires are at the same (acceptable) pressure.

 

tpms is one of the few new age add i do like , here is AZ i see alot of people driving on nearflats , and the road are filled with tire gators year round !!!

my G8 the system was screwy , fronts would go off around 30psi , and rears 35 psi , i think the alarm was set near the door sticker psi ratings , i usually set the tires to my gauge and my normal settings , then adjusted to to keep it above the warning when it was coldest out

 

That would be insanely annoying. I've never owned a car that set off the alarm before the high 20's.

 

yes it was , sucks keeping the rear tires set in the mid to high 30'a for cold pressure , nothing like wearing the centers out before the outsides
