Going 12 wide from 10 wide wheels

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 ?

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.

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

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

      Some Assembly is Required

      By Grumpy Bear · Posted

      Average Assembly 4.8%   That's the likelihood of a light duty vehicle reaching 250,000 miles. Link below has the stats on this. Among pickups the 350 series (Dodge)  and higher (450 Ford) are most likely and nothing American built in the lighter trucks pegs a number higher than the overall average.  200K and up is the stomping grounds of Asian vehicles. Toyota Sequoia the leader at 39.1% probability.      https://www.autoweek.com/news/a68886903/vehicles-most-likely-to-last-over-250000-miles/   Likelihood drops dramatically at 100,000 miles of reaching even 150,000 miles. 250,000 is deep in the tail of the curve.    I've been told by the 'experts' that I don't need oils of the caliber I use. My high viscosity is damaging my motors. Ash content it to high and WILL foul plugs and kill cats and O2's. I don't need that much ZDP; my choice is over added and not cutting edge. I change it to often. I baby them to much.    Three Honda's reached 200K + and none used oil. All Red Line motors. All sold to friends or family. One Toyota reached 300K using oil, Pennzoil. Dizzy 300K using QSUD until it cashed the rings at 80K then whatever but often ever since. Did you know this engine still sports the OEM timing chain and is dead silent? Pepper spitting into the wind short of 200K, Red Line and changed often. Uses zero oil. A HPFP and a pinion seal. Still using most parts it left Fort Wayne with. So 50% of my vehicles have gone past 250K and 100% of the last half dozen past 200K. Of these two using "shelf oils' did so using abnormal oil and the four that used a premium boutique oil did not. There might be something there the experts have missed. 🤔

      “Service Emission System” & “175 miles until “65 MPH Max Speed”

      By ManyCamaroz · Posted

      It's not that it sits for extended periods. I drive it every couple of weeks. However, I did consider draining the DEF and replacing it.    Don't you get a "Poor quality DEF warning" if its bad?

      Try draining the def and relacing with new if it has been sitting for a long time. Def does go bad after a little while.

      2015 Silverado with HUD retrofit/upgrade.

      By Thestonedone · Posted

      Thanks @Viktorrocks15 if you are still out there.   I followed your instructions and worked out great, went to the scrap yard and procured 2016 escalade cluster, hud, bezel, and switch. Got lucky and found a Camaro in the u-pull with the HUD bezel.   I made my own harness with these diagrams: https://www.gmupfitter.com/wp-content/uploads/2022/10/23_Escalade_Escalade_ESV_Electrical_Body_Builder_SM_en_US_2022OCT25.pdf   I used escalade cluster because its the best one that will work IMO. Still need to get it programmed but it looks really good.
