Tire over inflation problem

[thebrad]

I've been running 60psi for the past few weeks and noticed this tonight:


So deflate or see how long I can go without issue?

What is it? I can't really tell, does the tire dip in?

[johnpr]

if the tire is just dipping in (like a valley) then it is nothing to worry about, that is where the material inside the tire overlaps and so it restricts the outward expansion of the sidewall. if that is a bulge that we are seeing than the plies in the sidewall might be seperating or have an internal leak at which point you would need the tires to be replaced

I had two tires split at the valve stem. One actually started to leak so badly that I had to change the tire.
My max PSI is rated at 44PSI on the sidewall, and I was running 55 PSI, but on the day of the tire failure, I filled them to around 55 or so ........... and found out later how inaccurate that tire guages can be. I was actually at around 65- 70 + PSI.
( So it's a good idea to check the pressure with more than one guage. )

In my particular case, both tires failed at the valve stem. In your case, it appears to be the tire itself. I would deflate to normal levels and have a tire shop check the tire.
Better to do that then to put you life, as well as others in danger for a few pennies worth of gas.

I have seen similar marks on tires before that were at normal PSI levels. It may be common actually , and something that you only notice in certain lighting conditions.
I actually had this sort of mark on the tires that I used before my current set.
It always bothered me.
I would get a second opinion from an expert.

Stay safe !

60 PSI ? What is the max. sidewall rating ?

[basjoos]

All of my Sumitomo tires have had that bump on their sides from day one, just an artifact of the manufacturing process. I've been running 60 psi in them since I got them last June with no problems.

[thebrad]

Sidewall max temperature is 51 psi.
The two pressure gauges I have read the same amount, albeit they are both rather shoddy.

Sorry I couldn't manage to get a better picture of it, but yes it's just a little dip in the sidewall that runs the height of the tire.

[johnpr]

nothing to worry about then, i've seen thousands of tires do that (used to work in a tire shop), its all in how its made and not a defect.

a good gauge is a must ,,, i like to look at cold and warm/hot readings on my truck

I'd like to correct the terminology a bit: I wouldn't say that was a tire failure at all. The valve stem and tires themselves are physically separate items. Sounds like a valve stem failure, not a tire failure.

My Accord also had a set of tires with the "dip" in all four sidewalls. I don't think the Goodyears on the Flea have them though.
