tires,,,, tread depth difference?

[hockeybc69]

I was in SD 2 weeks ago and managed to shred a Hankook tire thats over a year old.

We couldnt get the spare tire off the truck!!!!!!!!!!!!!!!

Long story short, a savior came to help us.

He got me a used tire on the rim. Its got 4/32's tread. My other 3 tires are at 9/32's tread.

So is there a true issue with tread depth being that far off? Or is it an old wives tale?

I would prefer to just drive on it for a while(however long that is)......

Is that cool??? Or is that bad???

I'm no expert, but i have had issues with trying to swap tires on 4x4 trucks. If on the front, it will/could cause binding on some models. That's why they say 4 new tires for 4x4 trucks. The binding in 4 wheel drive is not pleasant sounding on asphalt.

I'm not sure about your measurements, but my tires were slightly worn and then tried putting on a 1/2 worn tire and got the issue with a dodge.

I believe in 2 wheel it would be OK if the orphan was on the front.

I saw the same ting that muleshack did on my old ranger years ago. Since then, it all 4 at once. God luck. But if your tires were worn enough, they might match now...

Year, make, and model?

You should be fine.

Is the used tire the same tire as whats on the truck? If not you could run into a traction issue.

The other problem is that tire will be out of sync with rotations. 4/32 isn't a lot of tread especially in winter. You will probably get by but if that tire is on the rear your looking at about 10k miles until it is worn out.

Your better option is to replace the tire with the same tire that is on the vehicle as soon as possible. Then get the spare tire carrier fixed.

Some of the better tire dealers have the spects. for the tires that they sell, tread depth, distance around,ect. You can then match different brand tires to the brand you have.

Tread depth can be an issue, but the real issue comes if the circumfrance of the original tires and the circumfrance of the one installed are way off. I believe Ford has a 1/2 inch differance allowed.

It can effect your antilock brakes and 4x4 operation if equipt.

Correct!

A different brand of tire would make little or no difference as long as it is the same circumference.

for towing i pull my 33x12 dura tracks off the back of my f150 and put little 225/70/r16s on the back and pull all the fuses for the 4wd stuff and it goes just fine..

Do you have ABS?

[pureinsanity]

If your tire is a year old, I would contact Hankook. Most of there tires have high mileage warranties.

As long as you can prove you rotated regularly, you should get new tires.

I've been running a newer tire next to an older tire on the rear axle of the Excursion for quite some time and have not noticed any issues. Both tires are the same size and brand just one is new and one is old.

If there is much difference in circumference of the tires on the rear of an Excursion, or any rear wheel drive vehicle with limited slip, it will cause your limited slip clutches to wear prematurely. Since the tire that is worn more, will be smaller, and be turning faster then the newer, bigger tire, the clutches in the rear diff have to slip all the time to make up the difference in speed of the 2 tires. For a limited time, it wont hurt much, but for extended miles, it will wear the clutches out. Then when you get stuck, only one tire will spin in the rear, rather then both.
