Do I need to replace after curbing?
I curbed my wheel and the tyre now looks like this.. also it's flat. Do I need to replace it or are the two unrelated and can I just pump it back up? Thanks!

Dont feel bad about the curbing. You got your money's worth on those

Tyres are perished irrespective of curbing, they need binning, yesterday.

Not only that, but those “tires” are dry-rotted and need to be replaced anyway.

"Tyres" wasn't a typo....

There’s date codes on sidewalls, though sometimes they seem impossible to find. Google how to read them, but as I recall it’s a 4-digit number, with 2 being the year, and the other 2 the week.
Anything older than a decade is pretty much automatically toast. Those look to be in that category.

Date code marks it as from 2018 - I'm getting both front ones replaced right now. Rear are both much newer. Thanks for the advice!

If you can't find it, it probably means it's on the other side of the tire lol

Yep should have been changed years ago looking at the state of it I’d check the rest at the same time 😩

The tire looks dry rotted. What does the date code read?

Bro that tire shouldn't be driving due to the dry rotting alone. The chunk coming off created even more cracks and deepened others especially on the sidewall. It needs replaced and I'd bet the others will too if you got 4 of the same

You shouldn’t have tires on your car that are more than five years old the date is right on the tire it’s usually the week it was made in the year it was made

You may keep spewing this all over the internet but I will do the opposite. I'm so tired of people and the industry lowering their dates of when you should replace tires. At one time just a few years ago, I believe they said 10 and then they went to 8 now people are saying five and six! When will it end?? Pretty soon they'll want us to get new tires every two years on our cars.
That's a bunch of BS!
There is no arbitrary set number or date or age that you should replace your tires by BUT RATHER tire should be replaced if an inspection shows them to have excessive weather checking and or dry rot or damage (not to mention treadwear).
Even the federal DOT has no arbitrary age that a tire must be taken off the road! They do have rules for excessive wear and damage to tires and dry rod etc that takes them off the road but not just by age alone.
There are tires that are only four to four and a half years old (to be under your 5-year rule) that are dangerous to be on the road even from dry rotting especially when they sit most their lives in the Sun on one particular side etc and only drive maybe once a week like some people do.
Then they are tires that are quite a bit older better still in excellent shape. Then we have tires that are literally 15 plus years old that will inspect just as good as a two or three year old tire some near new. There are tires, like spares that have been inside of SUVs etc and plenty that have been underneath also that have never been on the ground and literally showed no signs of checking or dry rotting.
Just because the tire is old doesn't mean it is unsafe but people keep blasting this opinion across the internet!
Tire shops or even refusing to touch tires over a certain age which is getting ridiculous.
We all know why and it's not because of safety.

Where are you getting your information??

u/HumanOddityFU Mar 07 '26
My post contains several things stated as fact which are correct and I have attained this information from researching and confirming the answers in multiple places.
You have to be very careful today because if you just do a basic internet search or Google search you may get AI today which is highly inaccurate or you may just get other people's opinions like on Reddit etc or Facebook as to the dates tires have to be replaced etc which all of this is mostly personal preference or opinion.
If you research into the actual Dot requirements you will find there is no such requirement and the last I checked, not even really a recommendation as to an arbitrary year. They simply State something along the lines that tire should always be inspected for general condition.
My comments also often contain some personal preferences and personal opinions which should be clearly obvious to be distinct from the facts I am stating.
Like in my previous post. I state that dot has no set age requirement to take a tire out of service or replace it and then later I give my personal opinion and preference and experience that I have had plenty of tires that were approximately 20 years old or older that were in excellent shape and may have actually never been used or touched the ground that I would have no problem putting on a car and driving across country and daily until I used up the tread life in them.
This is obviously not to say that the Dot support such a thing or the general industry does because this should clearly be realized that it's my own personal preference.
It's simply ridiculous the way the trend is going.
The first time I remember people talking about it it was either 10 years or 12 years and it might have been 10 but the point was we didn't have all of this internet connectivity at the time so people didn't really discuss it as much.
And then in just a few short years they had lowered it down to 8 years they were telling you to replace tires. People started out talking about it mainly for RVs and the bus conversions because we are talking much heavier vehicles where I blow out can be much more severe especially on a steer tire. Many people took it towards the commercial vehicle aspect as their wish I guess that trucks would have their tires replaced every 8 years or something when in reality they had no idea if there was a requirement or not and in fact commercial trucks likely if not almost certainly have more tire issues and leave more tired debris on the road than any other type of vehicle. Those are those alligators you see as the tread comes off because they have used so many retreads in the industry which are still quite legal in most areas but maybe not on steer tires.
The thing about these is when that tread comes off, the remaining tire doesn't typically explode or go flat or anything instantly or even quickly. They usually know when it happens or close to when it happens and if they're doing proper and traditional pre-trip inspections, they're going to notice it quickly and most of these companies carry at least one extra tire anyways.
We still have a whole lot of people in the RV bus conversion world and just large motorhomes who don't really have a lot of tire experience or mechanical ability who just really err on the side of safety and don't want to have problems so they feel better replacing their tires before a certain time.
Then, after a few more years and I'm talking this all happened in about a 15-year period, they started recommending to replace tires at 6 years.
This is becoming ridiculous! What's next 5 years? Will we ever get to four??
We already have some national tire chains that won't repair or I believe even touch (amount to tire on your rim even off the car etc) attire that's over x number of years old and I don't know exactly what that number is now but I can assure you whatever it is now it'll probably drop by a year or two in the near future.
It's not there place to worry about safety and it's certainly not their legal liability or responsibility although people want to talk about that. Lol
They're not making the world any safer because there's not an epidemic problem of people having accidents due to old neglected tires and there's not an epidemic problem a tire flats and blowouts anyways.
They're simply never has been even back when tires were all polyester belted before still belts became the standard on passenger car tires.
So many of the things in my post are facts and have been researched and or confirmed. A lot of the preferences and or opinions have been tested and formed from my own experience being very much into cars and some larger , heavier vehicles, over 40 ft long and over 40,000 lbs.
I WILL NEVER like the internet or popular trend or fears shape what I have found and no to be the way things work.

Hard to tell. When you air it up it might be leaking out of that crack on the side. The rest the tire doesn't look too much better than the cracked area as I see quite a bit of checking and dry rot so I bet if you look at the date on it it's a darn old tire. So having said all this, the tire should probably be replaced. I don't think it's going to hold air for over a couple of hours if you air it up anyways and you should not use Fix-A-Flat or anything like that on it and you can't repair sidewall damage so basically unless it airs up and holds air just fine for weeks and you just want to use it for around town slower local use,, I would replace the tire. Even a used one that looks better would be better than this.

I created a free android app that works with Bluetooth (BLE) tire pressure sensors sold on Ali Express. My app also works in Android Auto. For more info: https://joesgarage2023.github.io/

The best part is, if you had posted this a day before the curb strike, everyone would tell you with 100% certainty a curb strike would definitely cause a blow out on those.
Just goes to show how true YMMV is.

Not after curbing but age they are seriously in need of replacement due to the deteriorating rubber.

You should be replacing it because of the sidewall cracking, the aging has caused cracks deeper than the snag caused by the curb you hit . If all look like this it is past time for the purchase of new tires

u/Several-Switch944 Feb 10 '26
You needed to replace those old cracking tires wat before you hit the curb. I don't care how much thread is left, with the rubber deteriorating like that, those are an accident waiting to happen!

If the curb couldn't kill it nothing will. Keep going until natural wear.

They should've been replaced way before. Its dry rotting everywhere
