Tires - Dry Rot?

[psu]

 

Purchased the truck May 2018 and it has 20,000 miles of light use.

 

Is this normal?

[Salsa De Piña]

It depends.  Where do you park, and what do you use to keep those rims shiny?

Park in the driveway and just car wash soap.

Not normal. However, depends on a lot. How long have you had the tires?

 

[newdude]

Tires suck lately.

 

Got a picture of the DOT codes on the sidewall?  Should be 11 or 12 digits and its printed on there like this:   XXXX XXXX XXXX.  The last 4 numbers are usually in an oval.  Last 4 is the production week and year of the tire.

Doesn't look normal to me. My '17 Silverado (with a 12-16 build date) has the 20" wheels/tires with original Goodyear tires do not have any side wall cracks @ 36k miles. Are both sides of truck like this (Driver/passenger)? Or just one side. Looks like it sat a lot in the sun. That's just my opinion.

12/17 build date. I bought it brand new 05/18.

It sucks man.



So 36th week of 2017?

All four are like this. No extreme exposure to sun. I live in Pennsylvania.

36 week of 2017
Between September 4th and 10th 2017. 

 

Every tire has a birth date—the day it was manufactured—and an expiration date that is six years from that manufacture date. Most automobile manufacturers warn drivers to replace vehicle tires after six years. To wait any longer than that is a gamble with tire integrity and is risky for drivers.May 17, 2019

A bit early to date out.

Looks like it has been run under inflated a-bit?

That rubber, especially near the bead, is a lot thicker than you think. The Dueler A/T RHS tires on our 09 Z71 did that when they were 3 yrs old, and I ran them for another 6 years, up to 75k miles, when they were bald, with no issues. And that includes numerous potholes, trips up to the 97mph speed governor, etc. 

 

If you are worried, Bridgestone will warranty for that for 4 years. Prorated. But at this point, you’ll pay most of the cost for a set of replacement tires that may do the same thing.

With the "checking" just on the bead area and no evidence of dry rot due to UV exposure on the sidewall, something strange is indeed going on here, perhaps like Karnut alluded to, under-inflation. If any members here have tire shop experience perhaps they will weigh in with expert opinion.

Thank you!

I monitor it on the screen, check them routinely with a tire pressure gauge and check the monthly diagnostic report emails.

I keep them at the recommended 35psi.

Good to hear but still a bit unsettling. I’ve never seen it happen on any of my cars over the years.

No sir. 35 psi routinely.

Looks fine to me. Seen far worse tires in my many years in the automotive business that people still keep driving on.

[pokismoki]

what kind of rubber conditioner spray do you use? armorall , 303 protectant, etc. etc.....?

 

might want to get a set of tire covers from harbor frieght $10 and keeps the sun off them when parked

IMO you got screwed on your tires.

No way I would drive on those.

I had a blow out on the freeway at 85 mph with tires not quite that bad looking and had $7500 worth of damage.
