2022 TRD PRO - Nitto's vibration at highway speeds "HELP"

[Mark4runnar]

Update 9.1.22

I have owned several 3rd and 5th Gen 4runners. They have performed well in all conditions including highway driving.

This is my first TRD PRO.

At highway speeds there is a noticeable vibration (between 55 and 80).
It now has 2000 miles on it and the vibration has been consistent.
I took it back to the dealer last week and they said the tires needed to be balanced, which they did at no charge.......that has not solved the vibration.

When I called them today to ask them to revisit this problem......I started to here excuses......"well the TRD PRO has off road tires", "you can't expect a smooth ride".

It's going back next wed --- the service manager will drive it.

My question is-------- are there any other TRD PRO drivers out there that have had a similar situation.
I realize the Nitto's have a more aggressive tread ---- but the highway vibration
is a bit of an overhang. I do put a lot of highway miles on getting to and from the trails etc.

Any feedback would be helpful. If my expectation are way off "straight talk " is welcome???

BTW I love this thing!!!!!

UPDATE:


JUST a quick update........Bristol Toyota has decided and received approval to replace all 4 Nitto's on my 2022 TRD PRO.
They are really good to do business with ----- if you are in New England, check them out..selling 4runners at MSRP, no dealer add-on's and work hard to resolve any outstanding problems.

My advice is too ask the service advisor to have a senior technician balance your tires with the proper flange plate adapter on a Road Force Machine.

I am sure something like this was mentioned in the above posts but I did not read through the whole thing.

I ended up junking the Terra Grapplers after 25,000 miles. While they were one of the few tires that balanced "ok", it only lasted till the first rotation.

I have since went with Michelins.

Thanks for the feedback------- the dealer did replace all 4 Nitto Grapplers..... road force balanced the new ones --- PROBLEM SOLVED

Glad you got it sorted out. My wife wanted to outfit her 2020 TRD ORP just like a Pro so I did the Pro wheels and Grappler G2s.

We haven't had any issues with them through 2 full years of use and nearly 22K miles. I cross-rotate the tires every 3K miles to keep the outer shoulders from feathering which is a common issue with all AT tires.

When changing from the crap all season OEM Bridgestones to the G2s, I noted an increase in tire noise and a very minor increase in overall vibration chassis at highway speed. I noted the same when adding Pirelli Scorpion All Terrain tires on our 2015 Outback. I don't care what AT tires you have, no AT tire will have the NVH characteristics of a passenger style/all season/performance tire. AT thread blocks are too pliable and big. Same goes for braking in the dry and wet. AT tires make dismal street tires. It's all a compromise.

hey guys, sorry to resurrect an old thread, but I also just purchased and mounted Nitto Terra Grappler G2s in 265/70R17 to my stock ORP a few weeks ago.

As a control, I had no shakes at all from the stock Dunlops, as well as no suspension mods on my vehicle.

The shop I purchased the Nittos from initially did a regular balance and I immediately noticed the shakes from 60-65mph on a long road trip I did the following weekend.

A few days later, I went back to the same shop and had them RF balance the tires, as well as provide me with the values. They recorded 12lb in the front two and 15lb in the back two. (Down from 19lb originally.)

The following day, I still noticed some vibration but a bit less, and more intermittent. I read from other posts that these tires like to "flat spot" more, especially when its cold due to the compound that allows these tires to last 60K and be M+S rated. However, I spoke to a Nitto rep who told me that shouldn't be the case at all.

Anyways, today I filled up my tires from 32 PSI to 36 PSI and got the chance to drive about 100 miles and mostly the issue is gone.

There is definitely some more road feel with these tires at this PSI, and on some roads going over 60mph, I still notice a slight vibration to the steering wheel, but not a steady vibration that I had observed before the RF balance. In other words, it vibrates on bumpier highway roads but no vibration at all on smoother roads.

I'll continue to monitor from here.

Hopefully that info is helpful to someone that is searching

Vehicle shaking at certain speeds is usually caused by tires that have worn unevenly. It’s usually cause from improper tire inflation, wheel is bumped out of alignment and not rotating the tires. If the wear is bad enough there is really nothing you can do except buy new tires. If they are new tires it’s usually a tire that did not mold properly and weight has accumulated in one particular spot. If it’s bad enough not even balancing can fix it. If your able to narrow it down to a specific tire you can take it back and ask for a new one. If not return the whole set.

Here are the trouble shooting steps I take. I try doing the cheapest stuff first. I test drive the vehicle between each step.

1. Check for proper tire inflation.
2. Rebalance the tires with road force.
3. Rotate the tire. I usually do this with the rebalance.
4. Do wheel alignment.
5. Have vehicle inspected by mechanics to see if there may be other causes.

If after all this and I still get vibrations then I buy new tires.

From my personal experience, when I bought new tires the shaking went away.

There are things you can do once it is worn into the tires. First, rotate the tires diagonally so the next wear is opposite of the current. Second, put balance beads in the tires, then have them road force balanced.
