Hello. I recently did a 3" front, 2" rear leveling kit in my 2016 Silverado. With the stock tires and wheels it drove and felt the same just slightly higher up. A week later I got the Kumho Road Venture MT71 in a 33x12.5R18. The tires looked great and fit well on the truck with the stock wheels. I did not do any kind of alignment yet. After driving 10 miles on these MTs it feels like the truck is sliding all over the road at any speed over 40mph. It is almost like being on ice. I am running 65psi in the tires. I daily drive this truck for about a hour a day.  Would this be an alignment issue or should I return these tires to Amazon for some ATs? I do not know anyone running this truck lifted with this size tires to compare. Anything would be greatly appreciated.

That's way too much tire pressure for a half ton. Back that way down to 40-45psi.

 

For sure you need an alignment too.

 

Do those and see how it feels, mud tires on the pavement are not going to handle like AT tires. They will be even worse in heavy rain or snow.

Just my experience, but I had Kuhmo Road Venture AT51, and hated them. Brand new they were just ok, but quickly lost wet traction. I'd stay away from the brand entirely.

The alignment wasn’t off too bad, it did help but still drives weird. Must be the type of tires. Going to swap them out. Thanks for your answers.

Try 40-45 psi
I had same problem
I changed the rear ****** ranchos out for bilsteins and mad a huge difference. But that pressure is way to HIGH

In my opinion Kumho only made one tire worth buying, ever.  The V710.  It was a good and very fast tire for auto cross.  I'd never buy anything for the street from them.  You should look at the Goodyear Duratracs if you want a very aggressive tire that works.

Its looks vs. function. I had some really nice looking nitto ridge grapplers Id wanted for the longest time, and while they wern't as bad as yours seem to be, they just didnt handle my 85mph commute speeds well at all (especially in the rain). I returned them to amz for full refund and threw stock michelins back on. So smooth and solid through 100. Those MTs wont get better - get out while you can if you aint happy...

So here's the results. Previously for the alignment after doing the 3" front and 2" rear leveling kit my alignment was only off on the right side camber by .90*, the toe was also almost exactly parallel where the spec was to be more slightly toed out. The person doing the alignment said it was close enough not to cause bad tire wear or drivability. Now for the tires. I swapped them out about 100 miles ago now. It is a night and day difference in drivability with the Nitto Ridge Grapplers. The truck no longer wonders and feel like its sliding all over the road. I know they are a different type of tire and the Nittos are more of a street tire for occasional off roading and the Kumhos are the exact opposite. I am happy with the Nittos and I wanted to share my opinion and outcome of this post thread in the hopes it will help someone with the same issue/questions. Thanks for the input everyone!

 Amazon will take a return on tires that were mounted and driven on?

Yes. As long as it’s within their return time frame.  I’m sure they wouldn’t take them back if you did a Smokey burn out though half of them but as long as they are in good shape.

Yep. You still gotta pay for the tire work from locals though...

I have a set of Kumho AT51......absolute junk, terrible in wet weather, so out of round did a Road Force balance and put the worse tires on the rear and the best on the front, never really balanced......30K and already worn to where they are useless in snow

      AFM Experience

      By Grumpy Bear · Posted

      Question @diyer2 on this line if you please. Are you saying the shudder is the system turning on and off at the frequency of the shudder? Guess I'm asking if you are saying you have seen it do this with the bi-direction scan tool in graph mode? If so have you been able to discern the 'trigger'. Something is telling to cycle rapidly.    My truck just started doing this recently. 197K on the clock. My response has been M5 anything under 55 mph. I treat it like a lugging stick shift. Gear down and let it spin a bit. Engauge M5, then tow mode and then M6 lets the trans stay in 5th but the AFM is active. Smooth like Skippy.    My thought was that as a machine ages the friction gets lower and as the system is load based, the lower friction would allow it to turn on at ever lower rpm until it reaches the lugging point. And yes I am ignorant of any minimum rpm requirement for the system. If you know that would be useful information.    As you know I run a Scan-Gauge II which allows me to watch the On/Off of the signal to the VLOM. While in the shudder mode I'm not seeing is cycle at that frequency or at all for that matter outside the triggers @newdude posted a few years back. Now is it possible that the refresh rate isn't fast enough to catch it? Maybe. It is why I asked my first question about graphing and trigging parameter.     As we have observed from members here the failure point is all over the map miles wise as you note yourself in your opening post. That by itself begs a few questions like fellows that comment on these lifters failing even after the system has been disabled. Long after. 😬   https://www.enginelabs.com/news/tech-tips-replacing-ls-active-fuel-management-lifters-with-melling/   The Gen5 lifters operate the same as the LS versions. In fact they are the same lifter.    https://www.enginelabs.com/tech-stories/sorting-out-gen-v-lt-lifter-failure-with-a-simple-valvetrain-fix/

      14-18 Sierra 1500 Heated Steering Wheel Help

      By SwitchBladeSierra · Posted

      UPDATE 2: Steering wheel control backlights and control of the cluster can supposedly be achieved by adding a wire to pin 20 of the cluster and tapping it to pin 2 of the main clock spring harness. I'm going to give it a shot - will update

      Seems to be Missing a lot of Updates

      By newdude · Posted

      GM Global A pickups 2019-2022 can do OTA programming for the radio.  GM VIP (GM Global B) can do OTAs for almost every module on board.  So a 2022.5 and newer pickup can do OTAs for recalls like the 2.7 fuel flow recall.  EVs get OTAs that improve one pedal driving, radio issues, HVAC issues, updated battery management software, etc.     So age of the vehicle/what GM electrical platform its on will alter what amount of updates can be pushed on OTAs.

      Upgrade to a 2026 AT4 with the 3.0L Duramax

      By Blade8971 · Posted

      Thank You.   So far my new ride is making me look like a genius for going with the 3.0L, as my first fuel refill occurred over three weeks from when I took delivery.  This engine combination is very amazing.  So far no issues and had not done a regen yet.

      Correct way to service 2024 l8t allison trans?

      By Chuck FB · Posted

      I am curious as to how much fluid you put back in the transmission ( assuming you had replaced the filter to compare to my findings ) and then went through the process of warming up the trans before pulling the check plug to drain out the excess and if you measured how much came back out.    I just found it surprising that some claimed a certain amount less fluid being put in and then draining some back out. The attitude of the truck as per if the surface is level and how the trucks stance is would make quite a difference since the check plug is right at the front of the transmission.
