I've been wondering the past couple weeks what's been with the wobble in my front end. I was 99% sure it was a tire, I just hadn't looked at them in a couple weeks. I figured they were out of balance and was just gonna swap the 2 up front. I had to do it at night cause it's 105 degrees in the day time. These tires have around 40k miles on them and are Bridgestone Insignia se200's. 3 1/2 years old. I see no quality in these tires and will not run a Bridgestone again, I've seen them die prematurely on other cars as well. And yes I know at 40k they are due for replacement regardless and the bubble isn't just the reason I won't run Bridgestone's, these tires just all around suck.

I'm interested to hear what people say the cause of this was. Was the tire properly inflated while it was in service?

Me too. Phoenix doesn't have bad streets either, not really any potholes. I've had the car since 185k miles in November. Since then I keep them at 36 psi and let them run down to around 34 then pump them back up. They weren't low when I bought the car and I assume the guy took care of it pretty good, he spent over $2,100 (yes, $2,100) in May of 2013 getting a power steering pump, radiator flush and hoses, transmission flush, all 4 new struts and an alignment.

I bought the car 6 months after he did that for $1,700 wink

Also he got a Maaco paint job about 6 months prior.

Date code is (5110)

So right at 3 1/2 years.

Hello, I'm with you Nick. In my case Bridgestones (a set of 4 Turanza with Serenity) which were touted as the cat's meow-and priced to match-disappointed the dickens out of me.

How an irregularity gets built into a tire is anybody's guess.
I was told by a seasoned tire guy that tires don't necessarily wear evenly. I think that's a good tidbit to remember.

You're far from being the first guy to experience a crooked, wavy tire let alone one made with a less-than-perfect batch of rubber compound. Kira

I had 2 tires do that out of a set of 4. Sam's Club Goodrich T/A's .
They are ~8 years old, but I also have a similar set of Sam's GY's about 9 YO that are still good. Both sets have 4-5/32" tread and even wear.

A couple of thoughts:

THAT is very likely a belt leaving belt separation - what is commonly called a tread separation. Yes, the Ford/Firestone kind of thing.

I'm guessing the tire has a cap ply and that is why it hasn't created a flap yet.

Heat is the great tire killer. Needless to say, Phoenix is likely the hottest major city in the US.

Second, the condition of the tire looks rough, but there aren't any tell-tale cracks which is the usual way to determine the condition of the rubber (A lesson here, folks!)

Belt leaving belt separations are fatigue type failures and are rarely caused by a defect. They are usually caused by some deficiency in the design (belt edge placement, rubber gauge, that sort of thing) Lawyers like to call these design deficiencies "defects" - and even NHTSA uses that term - but that's not the way normal folks talk.

Underinflation and overloading can lead to those kinds of failures - and it would take more than just a few photos to be able to see if that is perhaps the case (Oh, and with all due respect to Nick, if I looked at the tire, I would make an assessment independent of his assertions either way. The tire would tell me if it was underinflated or not.)

It is also possible that a cut could cause that as well. Steel belts do rust - even in Phoenix.

Regardless of the cause it looks like the time for new tires.

I'd definitely replace them anyway - even if they weren't having the belt separation issues, they are way past the point a tire should be replaced (in my book)

Looks like hot pavement effects. Very similar to what I see on passenger car tires in the Caribbean. No excuse for the bubble though... Cant say how it was caused, but wouldnt be secure on those, even in the desert...

If you ever had a flat tire repaired with the "rope" it can eventually cause a ply separation which will cause an out of round condition which will cause the tire to have a "bounce".

The proper way to repair a tire puncture is from the inside with a patch stem pulled through the puncture hole.

I wouldn't have guessed the heat could make a 3.5 year old tire look that bad. The rubber chunking off looks like the cheap hercules 8 year old snow tires I ran for 3 summers...
I guess you don't get much rain, but those tires would need some extra care to get around safely.

It seems you need to pick a new tire based on its resistance to aging from heat?

Right on!

I spent several years retreading truck tires, That is a casing separation.

Cut out the blister. It would be interesting to see what's underneath . I bet you will find Rusty belts.
