These were E-rated tires and if there is one thing Ridge Grapplers do well its being a quiet AT tire. The Coopers sound like they may be slightly louder but I cant really tell. My truck is super noisy with wind so tire sound is the least of my worries

Ive been reading this thread and I'm on 35x12.5R17 LT E rated Ridge Grapplers... I went RG's because I read reviews on Coopers ST Maxx having issues with balancing and some people having wobbles. But this was maybe 2 years ago.

I've had gone to big bear with fresh powder and slushed road conditions and RG's were good ... Ive have duratracs make me spin, slide and drifted side ways on 2wd; on a slushed up road...

ps. I dont rock crawl or do crazy trails ... kinda hard with the family and baby in tow.

worst roads Ive done are White Mountain 3N17 and Edison RD at Night

To clarify RGs are terrible in deep snow in off-road conditions. I’m sure they are fine in a few inches of snow on the highway.

Here’s a shot of me literally inches away from rolling off a shelf road because my Ridge Grapplers had no lateral traction and I just slid to the edge of the trail. My buddy in the GMC Canyon waltzed through this section in Patagonia MTs with no issue. I was also constantly using my winch to pull myself through while he was just pushing forward. Never had issues like this with any of the off-road tires I’ve used over the years.

Ok Im not arguing your experience... But I'm sharing mine... I've been in Big Bear here in SoCal and it was powder and even slushed roads... Looked like the same kind of roads your on and I had no issues. The only time I've ever experienced spinning or sliding side ways is or was on Duratracs and I was in 2wd ...

The reason I so quickly ditched my RGs is because they were simply the worst tire in the snow I’ve ever used. My truck has never been so unstable. This isn’t even subjective. I’ve been on many, many different types of popular tires and these RGs just don’t perform. Even my Falken MT 01s, a mud terrain, perform better in every way, especially the snow and slush.

All good man I think we are just both trying to share our experiences. The picture above is an unplowed forest service road high in the Sierras (6000ish ft) with at least 8ft+ of snow underneath my tires. Snow on top of pavement is a little different, same with powder and slush conditions.

Understood ...

But I will tell you Cooper STT MAxx are my next set ...
Did you have issues with balancing them ???
And how many miles have you run on them ???
What PSI are you running on your Coops on and off ???

No balancing issues and no vibrations at all on the STT Maxxs but I only have maybe 15 miles on them. Running about 38 psi currently.

Any pulling to the right at highway speed?

I was looking for that but haven't felt any. However, I did not try braking hard at 65 mph. Im sure its there most likely from the aggressive tread pattern.

I recently ditched my ridge grapplers for a set of patagonias. At almost half the price of the ridge grapplers and more sipping, they have been a great tire so far.

I have about 7000 on my 285/75 St Maxx. I came from RG's in 305/70 and 285/75.

I have had no issues so far with balancing, (One rotation so far with no weight change during re balancing or re alignment nesecary) although it did take a good bit of weight per tire. However, so did the RG's. I run them at 38# front and rear on road and after some experimentation found 18# to be a good inflation in most off road situations including deep snow. (I've got about 900 miles off road right now)

As to the other question about pulling (I read about that prior to purchasing also) They had a bit of pull to the right for the first 3000 miles then that resolved. They do follow grooved highway some. I just drove to SLC from Denver last week and had no hand fatigue or stress from driving.
FWIW I didn't find the RG's good in any snow condition we have here in Colorado. If anything they were better in deep snow than powder, slush or snow over ice. The St Maxx are much better in the snow overall.
I had awful warranty issues with Nitto on my 305/70 RG's and couldn't consider using anything from them again.

Just a bit but only for the first 3000 miles then it stopped. They do follow grooved highway surfaces a bit

I am going to try Toyo RTs pretty soon.

To be fair, RGs are not 3PKSF rated so if it works great, if not i cant fault them. I do use my tools as intended and would personally avoid AT tires for winter as they get super hard in colder temps (wrong tire compound). I have dedicated winter tires and would never use AT for snow because every edge in stopping counts. Traction to move isn't my top priority in those scenarios as all vehicles are equally disadvantaged, 2WD/4WD are all equal because they have 4 brakes when you need to stop in an emergency.

I'm so far pleased with RGs, even traveled in mud when i shouldn't have been without too much issue. For road and fire-roads and rain I have had no issues at 5K miles or so.

First real offroading trip will be in September with a course instructor. The GY Ultraterrains before them were quieter and reasonably beefy and I may go back to them in future. They were also 3PKSF rated in case you do get surprised in mountains by snow/ice, but I still recommend using dedicated winters if possible.
