Going 12 wide from 10 wide wheels

[gapple12]

So, I recently switched from a 10 wide to a 12 wide wheel on a Nitto Ridge 35 tire, same tires on previous wheels. Tires only have about 10k on them. I also had them rotate the tires for the first time. When I drove the truck home, I was shocked how bad it rode. I had 12 wides on my last truck and it was nothing like this. Checked air pressure and it was good at about 37. Seems like the tires are riding real bumpy now and I feel every little crack and bump in the road plus a slight vibration anything over 40mph. Doing 70 this morning on my way to work was just awful rough. Is it possible they rotated the tires wrong ? Doesn't seem like there out o balance from the rough feel.

What is the section width of your tires? If you are stretching them to fit the 12's, then that could be an issue. It more than likely has something to do with the new wheels since everything was fine before, whether they are too wide for your tires, or one is out of round.

The Tires are 35x12.50R20 on a Gear Alloy big block 20x12. I called the tire shop and he said he did a X pattern on the rotation and I might be feeling the tire adjusting. I thought you only rotated off road tires front to back, not crisscross ?

Generally if the tire is not direction dependent, you want to rotate the tires through all 4 positions after 3 changes. See the images in this link. Rearward cross is most often used for 4x4 trucks.

 

Front-to-back is only for tires with a specific tread pattern that is direction dependent.

So, if the rough ride is caused by the 12" wide wheel, would going to a wider tire fix that? For instance, I am running a 12.5 wide tire, what if i went to a 13.5 wide tire ? 

[Jglew82]

I can't say for sure. The reason I asked the width of your tire is I've seen many people stretch narrow tires onto very wide wheels and they ride like poopoo. Usually for a x12.50 tire, they recommend a wheel width of about 8-9/maybe 10 inches at most, but plenty of people run 12 inch wide wheels with that tire size. It's tough to say what exactly is causing your issue from across computer screens, but you might want to have them verify balance if it's that bad. But generally, yes, when you stretch a sidewall out a bit to fit wider wheels, the ride tends to stiffen up a bit.

Are the wheels hub centric or lug centric?

 

How are they balanced? With a dynamic balance or a static balance?

Were they road forced balanced when you switched rims?

Did you ever figure it out. Mine is doing the same after installing 35x12.50x18. Took it to 2 different shops to have them balanced again. Going to try the balance beads in the morning

With mine, the ride got worse going to the 12 wide wheel. Every shop I have called said that is the case since i am stretching the tire. With these bigger tires and wheels, the factory shocks and struts cant handle them well so you feel everything. I am going to swap out my factory struts to a Fox coil over or Rough Country Vertex system and see how much better it is.

Well that sucks to hear. If this balancing beads don’t work ( which I’m pretty sure they won’t). I’m just going to throw the factory tires back on and sell these tires

OK, well that is an off-brand tire. In my experience, sometimes a generic tire will vibrate and have a hard time balancing. They dont get the best QC before they ship out and you might have one that is bad. I have had some black bear tires that would not run smooth no matter what. Also had some atturo tires with the same issue. 

[dctackett10]

Yea. That’s what I’m thinking. I went cheaper tire and now I’m paying for it. (Although 180 dollars a tire, isn’t cheap lol).   

 

Should of went name brand. Kicking myself for it 

[dctackett10]

In your experience. Should I try a different brand at 35x12.50x18. 

 

Or  or just go a little smaller like at a 265/75/18 Which I think is like 33/10/18
