Blowout

[Wytchdctr]

For me it was a snow thing. At the time I used to live at 10,000 ft, work at 9,000 ft and pass 11,000 ft going to and from work. To say the least snow and ice were common. Thats why the tires were off that quick for me

I normally run summer tires and just deal with the one day of the year we might see snow or freezing temps on the gulf coast. It just REALLY sucks to run summer tires if there is snow or ice. I was once forced to get a hotel room as I could not make it the hour drive home. I could not find enough grip to be close to safe. Lucky the guy was nice and pocketed the cash I had on hand... but it's worth it for the other 364 days a year to have more grip in the wet or dry.

At that much wear the OP is looking at either close to 50% wear if its the factory Hankooks(I was able to get over 50K with the Frontier) or more if its the factory Bridgestone tires. With that said it is actually enough of a difference that it will cause issues you dont want. Yes the front and rear diffs are open bit if you have more than 2/32nds tread difference between tires on the connecting drivetrain components you will simply have issues. That is why on 4wd and AWD vehicles need to replace all 4 tires at the same time most of the time. 2wd vehicles you can get away with an axle at a time.

As for upgrading tires.... Yeah I would take advantage of that too

AWD with limited slip diffs, yes. 4wd with open diffs, not so much. The most you might see is some slight bucking in 4wd.

Two different animals.

In 4wd one front an rear wheel are locked in rotation at the same pace. If one tire is nearly worn out an one is new you could get some bucking like you get when you turn on dry pavement in 4wd. I don't know the potential for difference but I remember when I had my wrangler the weak D35 rear would break easily an many replaced it with a ford 8.8. Jeep used a 4.10 gear an ford used a 4.11 (or the other way around I don't remember) an the guys all said it wasn't enough of a difference to hurt anything an ran them like that. Putting the new tire on the open wheel would prevent a potential problem.

I went to 265/70/17's on my truck but left the spare for the 255/65/17 knowing I won't be able to use 4x4 if I have to put the spare on. If I off roaded I'd upgrade the spare too.

True to an extent. But 22k miles is far from "end of life" in my experience.

My Bridgestones were replaced with just under 24K on them. They had 2 or 3 thousand miles of life left but they were loosing wet grip an winter was close.

Well those are even shittier than the Hankooks then.

Those tires should be about 1/3 gone.

Doesn't matter if you have a limited slip or not. In a AWD yes the transfer case is considered open but only to allow a certain amount of difference from front to rear in a turn.

The bucking you are taking about with a 4wd is the big problem and will result in drivetrain damage.

As for the factory tires offered on the Ranger... You have the Bridgestone Dueler AT RHS and the Hankook Dynapro ATM.

The Bridgestone has a UTQG rating of 400 and no specified tread wear warranty.

The Hankook has a UTQG rating of roughly 560 and has a mileage warranty of 50,000.

What is the number on the UTQG rating representing? To an extent how many miles the tire can go. If memory serves me right the DOT standard for a regular passenger type tire is 400. A higher number will result in more miles the tire should last. A lower number means the tire won't last as long(less then 400 are usually the high performance summer tires).

Now as I already said I was able to get a little over 50,000 mile out of a set of Hankook Dynapro ATM's with my 2016 Frontier. As for the Bridgestone tires I only had 7,000 on them before going to snow tires. Even with that little of mileage the tires had a fair bit of wear. Just look at the picture below.

So depending on the tire the OP started with will depend on the wear and still having half life would constitute replacing all 4 tires

My truck has the Bridgestone's. When I bought it new in May '21 it seemed to not have a deep thread depth to begin with. Now at 15K, I have about 3/16" before the wear bar.

A slight amount of bucking won't damage anything. For example mismatch in diameter for a spare.

And the UTQG rating does not specify "how long a tire will last."

It tells you treadwear, temp range, and traction/grip


It is a multipart rating that may tell you how long a tire will last. But there are many variables.

I, myself, have gotten over 30k miles from 300 AA A tires. It's all about road surfaces and your driving.

That being said those Bridgestones apparently wear for crap. And if they are that shot at 22k miles then it's probably not a good idea for constant use.

As long as the tire size is the same it won't act up too much. If it was different sizes front and rear and the vehicle was designed to have same size on all four then it would cause major problems. I have actually seen this when working at a Nissan dealer

What happened at the Nissan dealer? I'm curious because if I get a flat my spare is 255/65 vs 265/70 on the truck.

What I would see(not often thankfully) is a vehicle would come in with two different sizes on the vehicle. One size up from and a different in the rear. After doing a tire rotate the vehicle wouldnt want to move because the smaller size was on the rear. Mind you this is on a vehicle that is designed for same size on all 4.

If you change tires size on the Ranger it is in your best interest to change the spare to match as well. For example if you have 265/70-17 tires and the spare is a 16 inch wheel a 265/75-16 will be just fine to get you to the nearest tire shop.

I don't think you would cause problems short term driving.
My guess is that there may be an ABS issue if there were different sizes front to rear on a vehicle that was designed to have all equal sizes. The ABS/traction control would see the fronts rotating faster than the rears.

The spare is 16"? I thought it was full size.

I had it off the other day to install shackles, didn't even look. I did fill it up though cause it had 20 psi in it.

Correct it is a full size. The wheel can be a smaller diamiter but will still have a full size tire. A compact spare is super skinny and usually only seen with compact cars

It has a larger profile ratio so the side wall is an inch taller to make up for the different rim size.

Here's a pic of the tread about a month before I replaced them. I admit to only rotating them twice during the 24K or they might have lasted a little longer. I can also blame the 93 octane tune!

That's rough.

I've had some Bridgestones come OEM equipped on a couple of Subarus. They were both different models, but neither were impressive in wear or grip.

Despite that I had some re0-1Rs that were the cat's pajamas. Almost as good as Azenis.

Careful now, you.might offend Doug with that picture of your used rubber

What on earth are you talking about?

 

[Langwilliams]

The guys at discount tire told me the replacement Bridgestones were a lot better than the OEM ones. The most important spec to ford was low price it seems.
