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

 

Is this normal?

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?

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.

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

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.

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.

      Some Assembly is Required

      By Grumpy Bear · Posted

      Average Assembly 4.8%   That's the likelihood of a light duty vehicle reaching 250,000 miles. Link below has the stats on this. Among pickups the 350 series (Dodge)  and higher (450 Ford) are most likely and nothing American built in the lighter trucks pegs a number higher than the overall average.  200K and up is the stomping grounds of Asian vehicles. Toyota Sequoia the leader at 39.1% probability.      https://www.autoweek.com/news/a68886903/vehicles-most-likely-to-last-over-250000-miles/   Likelihood drops dramatically at 100,000 miles of reaching even 150,000 miles. 250,000 is deep in the tail of the curve.    I've been told by the 'experts' that I don't need oils of the caliber I use. My high viscosity is damaging my motors. Ash content it to high and WILL foul plugs and kill cats and O2's. I don't need that much ZDP; my choice is over added and not cutting edge. I change it to often. I baby them to much.    Three Honda's reached 200K + and none used oil. All Red Line motors. All sold to friends or family. One Toyota reached 300K using oil, Pennzoil. Dizzy 300K using QSUD until it cashed the rings at 80K then whatever but often ever since. Did you know this engine still sports the OEM timing chain and is dead silent? Pepper spitting into the wind short of 200K, Red Line and changed often. Uses zero oil. A HPFP and a pinion seal. Still using most parts it left Fort Wayne with. So 50% of my vehicles have gone past 250K and 100% of the last half dozen past 200K. Of these two using "shelf oils' did so using abnormal oil and the four that used a premium boutique oil did not. There might be something there the experts have missed. 🤔

      “Service Emission System” & “175 miles until “65 MPH Max Speed”

      By ManyCamaroz · Posted

      It's not that it sits for extended periods. I drive it every couple of weeks. However, I did consider draining the DEF and replacing it.    Don't you get a "Poor quality DEF warning" if its bad?

      Try draining the def and relacing with new if it has been sitting for a long time. Def does go bad after a little while.

      2015 Silverado with HUD retrofit/upgrade.

      By Thestonedone · Posted

      Thanks @Viktorrocks15 if you are still out there.   I followed your instructions and worked out great, went to the scrap yard and procured 2016 escalade cluster, hud, bezel, and switch. Got lucky and found a Camaro in the u-pull with the HUD bezel.   I made my own harness with these diagrams: https://www.gmupfitter.com/wp-content/uploads/2022/10/23_Escalade_Escalade_ESV_Electrical_Body_Builder_SM_en_US_2022OCT25.pdf   I used escalade cluster because its the best one that will work IMO. Still need to get it programmed but it looks really good.
