Tires look brand new, but are 11 years old. Keep or discard?

[Hay Dude]

Good idea, thanks.

I can check around, but can't wait long for some to show up-- buyers are "kicking the tires" right now.

If I take the current ones off, the only use I've found so far is to promote catfish spawning. Of all things!

Is this a motorhome? I’m thinking 8 tires means a 6 wheeler motorhome with a single rear wheel pusher axle? Wonder if a farmer could use them on a “low pro” truck round the farm.

I’d list them on FBM for $1,000. Someone will buy them. There’s a lot of useful places for those tires other than the family motorhome.

A little different scenario but related to tire age. Last year had a blowout with tractor and bush hog loaded on trailer. Checking tire pressure and visible inspection before trip, 2/3 of the way home had a blowout. Had to hobble down road until I got to a country church parking lot to put spare on. Was afraid the remaining tire on that side would blow to due to all weight on 1 tire but got lucky. Went next day and replaced all 4 with new 8 ply trailer tires. Tires were from 2011 so 13 years old and had just pushed my luck too far. All tires looked in very good shape with lots of tread but 1 couldn't make the trip. Believe from now own no more than 10 years for my trailer tires.

I have tires older than that on my truck and my stock trailer. I was mistaken. It’s 6 years on the date code where most tire shops recommend replacement.

In such instances, the end of the warranty period is when the mfgr. recommends replacement.
USDOT commercial regulations prohibit tire use after 10 yrs old. Private non-commercial vehicle tires are not regulated.

If I sold tires I too would recommend replacing tires after 5-6yrs.

My wife’s 2015 Jeep Wrangler Rubicon has only 37,600 mi! Always garaged. You guys got me thinking about changing them out, I know what she would say, that would be a big NO!!! She’s the only who drives it!

I have 8 truck tires-- size 295/80R22.5 Load range H.

They look brand new, have under 1,000 miles on them, but are 11 years old. They have been mounted on a truck that has been rarely used, stored indoors, and only occasionally driven. People are telling me to throw the tires away and replace them. A new set, including installation, is close to $10,000.

Q- are they safe to use? Should I replace them and be "better safe than sorry?" Does indoor storage make a difference in the recommendation to replace every 6-10 years regardless of mileage?

Other than discarding, is there any good use for these "like new" tires I would be removing?

Sorry to be the bearer of bad news, but those are unlikely to be safe, even as a backup spare. The age of the rubber (degradation) is one thing, but so is the rusting and degradation of the steel in the belts. With a tire in frequent use, any dampness or water that migrates into the tire evaporates back out of the tire, and any rusting is ground up/off by the flexing of the belt. Stationary tires are the worst in that regard, even though the truck was stored indoors.

I would look for non-vehicle uses. E.g. rope swings? Loading dock bumpers? Drags for leveling soil?

Sorry.

All the best,

Peter

Looks like a Rubicon that has never been off pavement! Because of where I live my rigs drive mostly dirt and gravel roads and those rocks really chew up the tires. Here's a shot of my Toyos at just over 24,000 miles:

A lot of the cheap ones, I've never heard of ... https://www.tires-easy-truck.com/tires/?filtering=295/80r22.5,relevance

If you considered a more common size, like what I and most 18 wheelers run down the road ... A 295/75R22.5 ... There are many more choices and generally better prices ... We pay about $50 for dismount/mount fee, as we carry a unmounted spare on our trucks, I'm a long distance truck driver.

We have a 300+ft. Gravel driveway if that counts!

My fleet has tires I bought going back to 1974 from Montgomery Wards Antique auto nylon construction and zero issues other than nylon takes a set the first few miles.

If I had to replace tires every 5 years on collector vehicles with some less than a 100 miles travel I think I would dig a hole and jump in.

My friend collects military vehicles and bought surplus wrapped WWII tires years ago with zero issue.

I do think longevity of modern tubeless tires with low rolling resistance just don’t last as long as the old stock.

Tandem axle trailers are a different class when it comes to tires… these tires often subjected to extreme stress… often sit exposed for months at a time and nearly all imported. I’ve seen trailer tires peeled off the rim on a local famous hairpin turn…

I have never had a tire problem with my single axle tires…

5 years on tandem and replace is good advice and what I do before setting out cross country.

 

[Shawn T. W.]

For the low number of miles anticipated ... I'd just buy recaps, if it's not a show truck ... My company runs them once they replace the original ones, all but the steers, can't run recaps on the steer axle ... Most major truck stop chains carry them, and some have a "lifetime" warranty!

That is interesting, but I don't know if there are any implications or potential issues from changing an 80R tire size to a 75R tire size?

I looked at the tires in the link, and noticed the weight rating of most were about 800# less load per tire. Times 8 tires, thats over 6,000# if I read that right.

The existing 80R's have something I am not familiar with-- a different weight rating whether used as singles or duals.

 

[Shawn T. W.]

Most all tires of this size have a separate rating for single or duals ...

Here is mine ...

At 6600 Lbs per tire in a dual set up ...is 26,400 Lbs per axle ... Most axles are only rated for 20,000 Lbs, and a tandem axle group with duals (8 tires) is only rated for 34,000 Lbs going down the road, unless you axles are spec'd higher, AND you pay for an overweight permit ...

Going from a 75R to an 80R changes the aspect ratio (tire height to width as a percentage). So the tire would be 11.25mm taller in an 80, from the axle to the ground and from the axle to mudguards, etc. on the RV. The 80 will be stiffer, which translates to a stiffer ride and and more vibration.

FWIW: I have been told by tire dealers that the 225/75R tires are an RV tire, optimized for low road noise and vibration absorption.

From personal experience, I can say that visiting a scale, and spending time with the particular tire chart for the tires you buy will make a difference in ride, and noise, if you match the inflation to the actual load. On one RV that we had the steers were at the absolute highest recommended pressure for the tires to meet the load, and the duals were at the lowest recommended pressure for just the RV. Adding a trailer, enabled one to add additional pressure if needed to take the added load. (Up to another 7k on the rears). Yes, 225/75Rs. That's a YMWV item.

All the best,

Peter

This is a good discussion and offers some education for all of us. I am not any kind of expert, but I have tried to learn enough to be safe and responsible when it comes to tires.

In the end, this is a judgement call, based on lots of factors, but we are responsible for consequences. I have lots of tires on different kinds of equipment on the farm. Do we "repurpose" old tires for use on our wagons? Of course we do, and many tires are cracked (not really a good measure of dependability by the way), balding, and 10-20 years old. But they don't really go off the farm...

An old Chevy dual wheel truck has tires with plenty of tread, but I only trust it to go on very short trips locally. Mechanically sound, but I don't allow anyone to drive it but me. Because I do know what might happen. A risk, but I accept it and prepare for it.

Folks, I have had tires correctly sized/rated with plenty of tread, less than 5 years old, self-destruct at highway speeds. Results are impressive - steel channel bed supports bent and twisted from impact and pieces of shrapnel flying everywhere. I have helped repair trailers where a tire let go and a steel radial "whip" destroyed lots of stuff...lots.

So when my one-ton Duramax leaves this farm with a heavy load behind it, it rides on the best Michelin tires I can put on it, properly inflated, and never more than 5 years old.

Why, when I could go cheaper? Well, put yourself in the pilot's seat: ambient temps are 95+ degrees and you're adding to the tire's temps at road speed with load and friction. You're heading down the road, cup of coffee next to you, good music...and a tire blows/delaminates. Now, picture in oncoming traffic an SUV coming toward you with your wife, or children, or grandchildren in it. Best way I can put it.

I may have a solution on how to repurpose my old tires and get some more use out of them.

My F-800 dump/scissor lift truck never leaves the ranch. Offroad use only. It uses 11-22.5 tires and they are in poor condition.

After a little research, it looks like I could put my former 295/80R tires on in place, and call it good? Plus I would have 2 as spares.

btw there is plenty of clearance around all the tires that could accommodate a difference in tire size.

Can anyone who has done it confirm the 205/80R-22.5 tires would fit on a rim that currently holds 11-22.5?

 

[plowhog]

Found this comparison ... looks like an acceptable substitution. The F-800 is off road only, 10mph tops, so I'm tempted.

A lot of work swapping all the tires around, but the price of new tires includes haul away of old-- so I might as well have the worst ones hauled away ...

So how do you plan to dismount/remount 11 year old tires if the claim is being made that nobody will touch 11 year old tires?
I say this knowing my tire dealer will happily dismount and mount them, but I don’t know about yours.

But I think that swap plan you have is an excellent idea.

 

[redman135]

One alternative noone has mentioned is to put new tyres on the steer and leave the old tyres on the rear.
Assumption: 8 tyre = 3 axles, steer, duals on drive, and single tyre lazy axle. If different axle layout please say.

 

[plowhog]

My friend Benjamin is quite persuasive ...

 

[Shawn T. W.]

Something not brought up yet, is that this size of tires have different intended axle use categories ...

Steer tires are the highest standard of perfection, and the most costly, they "can" be used in the other two categories (drive, trailer)

Drive tires though, can't be used on the steer axle, but can be used on a trailer ...

Trailer tires can not be used in the other two applications ...

However, for long life, it's best to use the proper tire for each application ... While you could put a steer tire on the drive axle, it won't last as long as a dedicated drive tires, as the drives are designed to "flex" more when torque is applied, think how the drag racers wrinkle up a rear tire launching off the line, that's hard on a tire, and it's done to a lesser degree every time I take off, or pull a hill ...

When we get a new truck, we order it with the tires we want (brand/model) ... Once the steer tires wear down to 8/32" (4/32" is legal minimum) they become trailer tires, and we get new steers ... Drive tires get worn down to 6/32" (2/32" is legal minimum) they get rotated to the trailer ... Once down to 2/32" they get turned in to be recapped.
