Sidewall cracking, replace?

[D-series]

3 year old Cooper Discoverer H/T, only one out of 4 tires has this cracking. Something I should be worried about?

 

[Lubener]

Being that close to the bead, I would replace it. I had four Cooper tires recalled years ago for cracking.

YES

What is the date code, How often do you use tire dressing?
Looks semi-cosmetic(!?) for the time being.
maybe @CapriRacer
could give us his opinion as a tire pro.

Was it ever run low on air? how much tread are on those?
I dont think it will blow tomorrow but might want to get new tires sooner than expected.

Replace your tires, if money is tight get some Goodyear Viva 3's they are good tires for the money.

45th week in 2019. Dressing is used quite often, usually Adams or Chemical guys, there’s 10/32 left.

10/32nd left? Then you don’t drive that much. Where are you located? Hot and sunny?

Ya I don’t, the truck sees maybe 8,000km a year, it’s mainly just used for towing my boat,Ontario Canada.

if you have 10/32 see if the tire shop will warranty it.

Ouch

The exterior rubber on the sidewall is non structural. That cracking will never be an issue, as it is the external protection for the tire. It is quite thick in that area. Although it is worth noting that when rubber starts to deteriorate, it can be a sign of aging or excess stress.

You should take a look at aircraft tires sometime! Loaded with similar external cracking, and 225PSI pressure!

While this is a light aircraft tire, it is perfectly acceptable and common. Additionally, this happens to "hangar queens" about as much as it does to aircraft stored outside. The criteria is whether threads (exposed fabric) are visible for 1/4" or not. Page 27 and 28 on the PDF.

Same criteria for sidewall cracking. Remove tire from service if fabric is exposed. And remember, this is for aircraft tires certified to land at 225MPH!

I wouldn't worry about it, looks cosmetic. Mount it the opposite way on the wheel if it isn't directional and if it bothers you.

"The solvent-based product is intended to leave a wet-appearance. They are sticky liquids, often clear in appearance, and contain petroleum solvents. While they make the tire look great, they can lead to premature cracking or drying of the sidewall. This can be a safety hazard, as it’s possible for tires to pop if the sidewall is cracked."

Use only water based tire dressing like 303 to preserve the rubber.

I don't like the looks of those cracks.

Goodyear prorated mine for sidewall cracking.
