Kinky Sidewalls?

[CAROLINA CUMMINS]

What causes tires to get those kinks or indentions in the sidewall. I noticed my new tires have some, but the Goodyears on my grandpa's 3500 were terrible, they had kinks out the wazooo!

I know hitting curbs will cause kinks in the sidewalls.

I think the Goodyears are just "naturally kinky"! I know the ones on my 3500 are, and have been from day 1. So are the LT235/85R-16E Wrangler HTs on my 5th wheel. Don't think it has anything to do with hitting curbs in my case.

That's how I noticed the ripples, I had scuffed my tires on a curb and was looking and felt the kinks. It doesn't bother me unless it is liable to come apart. Is it just cosmetic?? Thanks

Caroline Cummins,



Dont know for sure unless you post some pics. It could be sidewall seperation which is bad. Can you post some pics?

 

[CAROLINA CUMMINS]

Sorry no pics, jrandol, Its not a seperation, it's like a ripple,indentation,kink etc... it's inward not outward. if you have ever seen the stock goodyears on the newer(than mine) trucks, you'll know what I'm talking about.

Ah, indentations. We use to get these tires all the time like that when I worked for a trailer manufacturer. Goodyear swore up and down nothing was wrong with them. Never had a failure in the 1000's of tires we purchased with the "kink. " They were almost all 235/85 R 16 Load Range E

Seems like all three different sets of tires I've had on mine did that. Michelins, BFG's and now Continentals. I think the Michelins were the worst. Don't know what caused it, but it seems like it was worse when working the truck harder, (loaded more often). Never caused a problem, though, so I never worried about it.

--kink--

that kink is there from the manufacturing process. thats were the side walls are joined so there for it is stronger there, and does'nt conform to the normal shape. because of the double thickness or what ever. if you go back to your installer, i think that he will tell you nothing to worry about. if it is, it's a manufacturing defect. look around, some manufacture have two, and some three in a side wall. depends a lot on size, and ply.

just my penny's worth.

Many years ago I bought a new car and noticed the "kinks" in the sidewalls. Took it to the tire dealer and he showed me a memo from the manufacturer (been so long that I do not remember which one) which indicated that such "kinks" were caused by the manufacturing process and that they were a normal. They apparently build radial tires in sections and these are where the sections are joined. Since then I have noticed it on many tires.

I remember talking to a tire shop guy a few years back. He explained how tires were put together. Some of them are like a two-piece tire. There is one seam that runs the length of the tire in the middle of the tread, on some. That is where the two halves are joined. Others have a seam running width-wise of the tire, about every eight inches. Supposedly, this is the better of the two. All of the tires I have run on my truck are put together this way.
