I got an email from out tech at work telling me that one of our E350 transport vans would soon need tires so I gave him a call.
This vehicle was on its original Hankook Dynapro AS tires at 110K.
The treads don't look all that bad and are certainly not down to the wear bars.
I found this kind of tire mileage on a heavy Ford van pretty impressive.
And here I though that Ford was cheaping out using these instead of Michelins.
Are the OEM Hankooks that good or is this typical mileage for an LT tire?

There's your answer. A transport vehicle that does a lot of miles, perhaps straight line miles on an interstate, will have long tire life.
 
That isn't normal mileage out but sometimes tires will be impressive. I have seen some Uhaul trucks (Michelin only) Pushing 100k on LTX M/S2 still easily within their specs. No idea why but some sets just refuse to wear out.

Than again I just replaced a set on a DC (15 foot truck) at 50k and they were done.

Friend of mine has a set of tires on his Cherokee (also Hankook Dynapro) that came off an econoline with 80K miles. They were the originals. Of course, after a few years on the Cherokee, they are bald.
 
Wow.....lol and I was coming in thinking this was a complaint thread :P haha....my grandfather was just pricing LT tires....and he was shocked that so many places do not offer a milage warranty on LT class tires....they explained due to the loads that the tires are capable of carrying, and they can't anticipate how they wil be loaded......or some baloney. lol He did find some that had a 50k treadwear warranty but they were pricey....
 
Good HD 3-ply sidewall cases too. I have the winter RW-11s on my 3500 D-Max. 275/65/20s on 20X9" wheels.
Mention putting HD LT tires on a 1500/150 and the usual hall monitors from the tire and automotive industry come out of the wood work.
 
We've gotten 80K out of those, but by then they're usually pretty rough/bumpy, the guys who do a lot of interstate driving get the big mileage out of them. Not me, too many back roads.
 
Not unusual at all. We always get well over the advertised mileage rating out of tires; most of our driving is straight highway driving. Before we sold our Subaru Outback we replaced a set of Michelin Harmony tires that still had 6/32nd's tread after 102,000 miles. They were replaced because of age, not mileage.
 
I just saw a team mate get 115K out of a set of Conti's on his Ford Escape. Not the same category as LT tires, but it sure does seem like some tires just won't give up, and not isolated to one brand.
 
Maybe it's time (again!) for my lecture on tire wear.

Most tire wear occurs in the cornering mode. Driving straight ahead is practically free.

That means that city driving wears tires quickly, and country driving does the opposite. That's why over the road trucks can get such good wear on their tires.

I've seen regular car tires go over 120K just because they were on a vehicle that drove between cities, instead of in them!

You will also find many RV'ers reporting 100K on their tow vehicles.

So it isn't only the type of tire that matters. It's the type of service.

What about alignment? Yes, bad alignment can cause tires to wear both rapidly and unevenly.

What about rotation? Yes, FWD cars wear their front tires about 2 1/2 times faster than the rears - and RWD cars tend to wear the shoulders in the front and the centers in the rear.

What about OE tires? Yes, OE tires tend to be made for fuel economy, so wear (and/or traction) is sacrificed.

What about tires with high UTQG waer rating? Yes, those types of tires wear better than tires with low UTQG wear ratings.

But all of the above pales by comparison to the affect of straight ahead driving has (or curvy roads!)

I to was surprised with the lack of mileage warranty on LT tires. After researching CR and reviews in general I narrowed it down to the Dynapro ATM or the Cooper AT3, I ended up with the Coopers because they had a 55k warranty and $50 rebate.

Shhhhh. You can't put LT tires on a 1/2 ton pickup!!!
 
There is a reason most LT tires don't have a treadlife warranty - and its tht the manufacturer has no way of knowing how the tire will be used. If its always at its full load rating, in an environment with lots of turning, starting, stopping - it'll wear out quick. Put the same tire in a nearly all freeway scenario, and not fully load it, and it will last for ridiculous amounts of miles.

And the hall monitors who insist that LT tires are needed on a 1/2 ton will appear too...

As far as putting them on a 1/2 ton truck, I don't think anyone has said you can't. More along the lines of it isn't necessary from a load rating perspective, it has adverse affects on ride quality when they are properly inflated (and not underinflated at placard pressure for the same size P-series tire), and will ding fuel economy due to the extra weight. You want to go that route on a 1/2 ton, go for it. Been there, done that, and don't need to go there again.
 
Fair enough.
But couldn't you say the same about any tire mounted on any vehicle?
The tire maker has no idea how any tire will be used or even what it'll be mounted on.
 
Just an FYI:

While P type tires are sometimes used in commercial applications, LT tires are more frequent and the warranty situation is much more abused. After all, LT tires are designed to be used on trucks!

That's why mileage warranties aren't as common on LT tires.

I would say the tire maker knew EXACTLY what vehicle the tire was going on.
