265x65r17 AT3s on stock Wheels problem

[Argyle Edison]

I read it 1000 times and done it on past vehicles with no issue, but I had these tires mounted a few days ago, with alignment, and they pull and tram line all over the place. I can’t deal with it.

I have rotated them with no change. Checked calipers to make sure nothing was dragging, and even had another shop verify the alignment was correct. (I do have about 3degrees of caster with SPC uppers, but this was perfect before the tire swap)

So, I’m left thinking that these wheels are just too narrow and not allowing the tire to sit flat ?

I’m running 32psi right now and I do have 1.25” spacers (have been on for years now)


I don’t even want to drive the damn thing right now. It’s that bad.

Could you guys possibly help me out? Shelling out money without a good plan (and shitty results) really grinds my gears.

Thanks


Additional info that might be useful:

2010 sr5
2” Dobinson lift (like butta)
Only think changed was tires

Only reason I kept these POS Wheels is for winter. I know the tires are rated for 7.5” wheel or wider, but I have read about plenty of people doing this.
This causes a conundrum as I don’t want to get new Wheels for winter, and don’t want to spend more money on narrower tires.
I had the same size tires on it for the last year or so but they were more of a street tire.

Thanks again

I'm running the same tires and 32 psi sounds way too low. I run mine at 36-40 psi depending on my mood and they seem to ride well. I do get a little bit more wandering with these tires vs my stock Dueler H/T's but I believe that's attributed to the more squared off profile of the A/T's vs a highway tread.

Anyway, add some pressure and see how they do.

I have the 275 70r 17 flavor (so wider) and run them on stock wheels without an issue. Mine are LT load range C and I run 40-42 psi. Are yours the p-rated or LT? I did have a small balancing wobble at the 65-70mph range but got it back in line with a road-force balancing at the Toyota dealer.

The tires you are running are actually smaller than stock. Don't know if this is the issue or not (stock size is 265 70r 17).

I have no balance issues at all (knock on wood), just a wondering and instability on our shit roads.

I can physically see the crown of the tread because the wheel isn’t letting the tire flatten our. I don’t know why it’s crap for me and not anyone else. Annoying to say the least

Thanks for the feeback. I’ll try upping the pressure.

Keep in mind that wondering can be function of the thread pattern and sidewall. On my 08 Wrangler I would swap (winter/summer). Winter was Bridgestone Dueler AT. Summer was BFG Wrangler MT (I think). The two tires handled complete different. the Dueler was solid and planted. The BFG was all over the place. Near the end I never put the BFGs back on. They were just to mushie, longer braking distances and so on.

As for the crown .. I would be worried about that. Have you done the chalk test?

Let the chalk tell you
You can also “calculate” your tire pressure with the chalk method. This involves coloring a section of your tire with chalk to see how much tread is making contact with the ground. Start by finding a flat road surface. Concrete is actually the best choice, but you can also do this on asphalt. Make a mark with soft chalk that goes all the way across your tread. Then, gradually drive your truck forward about 50 feet and then backwards 50 feet.

Analyze the chalk on the tire. If the chalk is only worn off on the center of the tire, reduce the tire pressure slightly and go through the process again. With the adjustment, you should see the chalk wear off more broadly. Keep making tiny adjustments in the tire pressure until the chalk wears off evenly and all the way across the tread.

You will have to complete this process for each of your four tires. Once you’ve found the right street pressure, add 10% to all four tires. Then, measure the tires and add pressure to balance them. As explained above, you need to measure from the wheel to the ground. Start by balancing the profiles of the front tires with each other. Then, balance the front tires again with the rear tires. Always adjust the tires with the smaller profiles by adding air.

The advantages and disadvantages of this method are the same as those involved in the second method above. If you go through the process correctly, you end up with the ideal tire pressure. But, this method is tedious and there’s a reasonable chance that you will make a mistake.

I agree except I’ve had AT3s on my last two vehicles without issue at all. Great tires.

I haven’t done the chalk test. I’ll give it a go. Thanks.

How many miles do you normally get from them?

I've had the General Grabber AT2 in the past and was thinking of using them on my 4Runner when the OEM wear out.

 

[Argyle Edison]

I’ll be honest, I don’t really monitor the miles like some do, but I easily get 45k out of them with normal driving 50/50. I’ve used AT3s on DDs and grapplers on my tundra. Love them both.

Do you know the dimensions of your rim?

I know my trail wheels are 7.5 inches wide. Could yours potentially be 7?

It's strange that you mention you've got a crown on yours. Definitely try the chalk test and let us know the outcome.

If you do have a crown adding PSI will only make that worse.

I think the issue is that you went with a tire that has a shorter sidewalk as well as the relatively narrow rim. Narrow rim probably pulls the sides in a little causing the crown.

This is correct, and the problem, I believe. The wheel is 7". Adding more air would definitely make it worse.

Couldn't do chalk test due to rain, but you can see just how rounded the tire is here

sounds like the alignment is off

Right, unfortunately it’s not. Two shops confirmed.

I'm sure you realize that you're running a tire that is smaller than the OEM specified size. I would guess that's what's causing your handling issues. You are running with less load capacity on a smaller diameter tire. Any particular reason for doing that?


OEM = 265/70r17 - 113S - 2561lbs - 31.7"

Yours = 265/65r17 - 112T - 2469lbs - 30.6"
