you forgot the most important factor, UV rays

Direct sunlight deteriorates rubber, a car that is always parked in a garage, tires will last longer, than a car always parked in direct sunlight,

Tire companies don't know where people will be parking, so they just give a general estimate of 6-8 years,

If your parking in a garage all the time, your tires can, and will last longer,

Now James, that is a welcome change to the fearmongering about replacing tires at 6 years, 8 years, or even 10 years. UV rays from the sun is what really destroys rubber more that oxygen, heat, etc. I have had tires on different cars last for 12 years, another car (garage kept, low mileage) now for 14 years. No dry rot apparent, good tread, driven at up to 70 mph. Yes, anything can happen with any tire, anytime, and other driving risks including getting hit by lightning in a convertible, no guarantee, but one of the above post with the limit of 10 years is not absolutely true. Too many factors to consider (example- curb rash on new tires- so bad)

That tire is at least 20 years old . 😁

For my personal ride I would run them a year or two more, for my daughter's ride, probably replace them.

I have 60 years of driving under my hat, she doesn't.

My experience and knowing what to do to control a blown tire is the advantage.

Your tires look about middle aged to me, but I don't know your roads or her "style" of driving.

If you can afford the luxury of new tires, go ahead, if not, then caution her about caring for what she has until funds are available.

Then put the old ones on CL and ask $125 for the 4 of them.

That is always a wise decision, you decide they are not suitable so your going to sell them to someone who probably knows less. Hopefully not used by their wife/daughter!

Blow-outs / blown tires on passenger vehicles are typically due to under inflation / leaky tire or rim edge; and prolonged driving with low pressure.
That's quite a difference from the first onset of tire rot with a some shallow hairline cracks showing on the surface.

Most often blowouts are seen with trailers, typically parked for extended periods of time, owner does not protect the tires, may see they're deteriorated or not and starts towing. Combine bad tire condition, some low pressure, heavy load, long trip ... and there you have another person with a blown trailer tire by the edge of the road.

A lot of new tires come with only 10 or 11/32 tread depth. At 5-6, start keeping an eye out and setting some money aside for a new set of tires, maybe rotate them one more time and then replace when they're getting to be 3-4 and next winter approaches, look for a later summer / fall special.

I just replaced the all seasons on our SUV at 3-4/32. I didn't care for going through another snowy winter with the OEM set, when we use the SUV most in winter.

When my tires are at that point in their lives I think about whether I will be taking any road trips. For local around town driving, I would run the tires longer. If I intended to do a substantial amount of highway driving I would replace them. A few years ago my tires were at that stage and my wife was driving from NY to SC, so we got new tires before she left. A car beside her on the interstate wiped out in rain due to hydroplaning, my wife maintained control. I am more concerned about high speed hydroplaning than a low speed blowout on a run to town.

I've not read anyone elses replies and sorry if I'm late, basically replace at 5 years, so yours are over due, doesnt matter the tread, the tread is only important if the tires are within age, after that, they are dangerous and a liability, your car is only as good as the 4 small points of rubber that contacts the road, your life and the lives of others are not
worth worrying about. Assuming you spent $100/wheel $400 for 4 tires cost you 18c a day over 6 years

you got your moneysworth !

One of our vehicles has Michelin Defender tires with close to 50K miles on them. The tires are 6 years and 3 months old. Tread is 5 - 6 32nds. Since the car will be around longer than the useful life of the current tires I figured I would just replace them now. I'm also curious if any of the photos show dry rot. Dry rot photos online typically show tires with far worse but figured I would share here for some feedback.
Thanks

I'll slightly correct myself, some vehicle manufacturers recommend that tires be replaced every six years regardless of use. In addition, a number of tire manufacturers cite 10 years as the maximum service life for tires. Check the owner's manual for specific recommendations for your vehicle.
For me it's not worth it, I have a wife and kid, my life is worth more than 400 bucks

Where in heck do you find any tires for $100 NEW?

see below, just a gustimate, depnds on what you want and how much you want to spend, you could even get part worn, I wouldnt get $100 tires though it depends on what car I'm putting it on, but if somone is worrying about changing tires after 6 years they sound frugal. and I had kumho's on my 1 series BMW, they are very good,

 

[ajaye]

The tires for my 2 series are considerably more than that; Pirelli's RFT 18" directional (AWD) there about $400 bucks each

 

[HotRodx10]

There's a few around that price in the size the OP is looking for; the only one I (well, TireRack) would recommend, for areas with snow, in that price range, is the Laufenn G Fit AS. The rest of the ones with decent ice&snow traction are $130 and up.

 

[HotRodx10]

see below,

All those are either off brands without objective quality or performance ratings, or dedicated winter tires, which will have no tread left after driving on them at highway speeds for a summer.

I had kumho's on my 1 series BMW, they are very good,

Some of the Kumho's are very good - the Crugen HT51, in particular, is excellent on ice; others not so much. Seems like they all have their good ones and not so good ones, especially when it comes to ice&snow.

I was spit balling at a 100 bucks a tire, I was just trying to make a point, whether it's 100 bucks a wheel or 200, it's still between 81c- a buck and a half a day for 6 years, false economy, just replace them.

 

[ajaye]

and then there are some people who don't care

 

[Frank4]

I bought a car that had been sitting there for three years. The man had died and it is a Honda Accord. It had new tires but the sidewalls did not look good. Drove it around for a while, not interstate driving. The mechanic said you have a big split on the trad which I had not seen. I quickly replaced all 4 tires.

 

[HotRodx10]

The risk of a blowout goes up every year, but the risk is negligible well past 6 years, and very small even past 10 years, if the tires are maintained properly (proper tire pressure, avoiding physical damage, etc.). If the tires are periodically inspected carefully, that small risk can be reduced back to the point of being negligible again, since most defects that would lead to a blowout have visible signs.

 

[ajaye]

Hit a pot hole a few times, and you don't know what internal damage you do to the tire, most people don't check brake and other lights, nor fluids, most don't even put winter tires n (depending on your region) a lot of people get in there car and drive, they assume it is all ok as there mechanic has told them so, most just put in gas and away they go.

Safety is about dealing/planning for the lowest common denominator, i.e the nut behind the wheel.

Get into a minor fendor bender and no-ones the wiser, kill somone or some people, police and insurance will be all over your car to ascertain blame. If you couldnt brake in time, because there was something wrong with your car, assuming you were not texting, drunk or doing your makeup, you are in a whole world of hurt.

Anecdotal evidence is an oxymoron and not data, just because you have driven on tires for 15 years, or your uncle bob has does not make it so.
Most auto manufacturers recommend replacing tires over six years old regardless of tread depth. Some tire manufacturers like Michelin and Continental give a 10-year limit. As rubber compounds age, they deteriorate and become weaker like other rubber and plastic components on your car.

If you wanna cut costs, tires are not the way to do it, your tires are probably one of the most important things on your car,
Generally, the overall size of each contact patch is no larger than the size of your hand, that's scary.
If you wanna be frugal, put in the cheapest gas you can, drive with the AC off, stop buying coffee from the drive through, use a cheaper hooker
but for the love of God, don't try and get a few more KMs out of a set of tires, it aint worth it.
I pay attention to my car and it's maintenance, I am a bit over kill and OCD, but then I don't want 50 grands worth of BMW failing nor costing me money.
I do appreciate times are hard people driving $200 beat up 25 year POS cars, so trying to justify 400 bucks of new tires is hard, I get it.
Heck my first car in Canada was a 12yo Dodge Neon,
it slowly fell apart but car's tires were impeccable, probably worth more than the car ?

Ferried me and my baby till she was 4 , which was the most precious cargo ever in that car, so no comprmises,
that was until some douche side swiped me on the 401 and wrote the car of.
Got $3,500 off insurance, which was probably 3500 more than it was worth LOL,
I guess everyone has a POV and argument for and against, nothing more I can really add that has not been said

PLEASE DRIVE SAFELY
