Pirelli Scorpion AS Plus 3 

Tires were new with my 2021 Tundra 4WD Truck purchase (Nov 2020). Nearly 60k driven to date. The absolute best tire I've ever had for highway wet road usage. You will hear the road roar; this has advantages especially when it comes to scaring off deer. Handles very well on dirt and gravel roads. Haven't experienced snow or ice, but would expect solid performance.

I can only compare them to the Wranglers. These are a big improvement. The first thing I noticed is how much quieter they are. They are by no means street tire quiet, but you won't have to crank the stereo up to drown out the noise as was required with the Wranglers. You will still get bounced around with the big bumps, but they handle typical road imperfections very well. Handling is about the same as the Wranglers, which is to say very good. Here is the night and day difference: wet roads. I used to cringe when I had to drive on wet roads, not anymore. These Nitto tires don't spin at all when taking off from a stop. I can force a spin, but that is on me. The safety factor alone, being able to drive with confidence on wet roads, made this purchase worthwhile.

Had some snow and ice come through. Mail truck had trouble getting up a hill, probably 20/25 degree slope about 50-60 yards. Put my bumper on his and locked in 4 low, no spin and got him on his way. I am impressed with this tire and will purchase again.

I live in northern Utah up in the mountains. The Nitto Ridge Grapplers have been excellent tires in snow, mud, sand and rock. I’ll be purchasing another set in about 3000 miles.

I decided my review of the Nitto Ridge Grappler would wait until I've seen them through their lifespan. After 40,000+ miles, it's time.
Overall, this is a really good tire. Would I buy them again? Yes, if I lived in a warmer, drier climate. Any hang-ups I have with the Ridge Grappler are probably as much about the Tundra's rear-end torque in 2WD as anything to do with the tire. I don't care about ride quality because...it's a truck. The ride was noticeably more stiff than the OEM tires, but you're moving up to Load Range E on a 1/2T truck. Road noise? That's what SiriusXM is for. Now for the Nitty gritty...
Dry traction: no complaints at all. Excellent performer. I live where the highways have lots of curves and I have no qualms with taking curves at 10-15 MPH over the posted recommendation. From brake to Wide Open Throttle there are occasionally some chirps, and there are short breaks in traction over the painted Stop lines at an intersection, but acceleration is confident, reliable, and predictable. Hard braking is just as confident.
Wet traction: under normal highway driving, performance is what you'd expect. Never had any problems in the curves. Acceleration, however...the light rear end and heavy torque makes wet acceleration interesting. Even at 40 MPH, throttling up for on-ramps on the interstate can get a little squirrelly when the truck downshifts to gain speed. Hard braking on wet pavement is better than the acceleration, but there's more weight in the front.
Snow traction: again, under normal driving on snow-covered roads, performance is satisfactory. There is a bit more understeer if you're in 2WD, and 2WD acceleration can be a challenge - even light acceleration from full-stop. 4WD in the snow feels like you could go nearly anywhere, even on hard packed snow.
Off-road: Dry or mud, compared to Courser A/T (2 or 3), BFG A/T3, and General Grabbers, one of the best of any tires I've had on any truck.

Stock Nittos terra grapler were ready to be replaced at 45k and was looking for something similar. Found Ridge Grapplers on sale for 166 each. Was sorta concerned about comments about road noise and wet traction.
This is a super quite A/T tire despite its aggressive look. They ride really nice on the highway and are great on my farm: wet pasture, muddy rutted roads. I've done nothing in heavy mud, sand, or rock crawling. I've had zero wet traction issues, zero hydroplaning even in heavy weather. Not sure why these other buyers were experiencing these issues. Possibly tire/ lighter vehicle weight issue, ?
I just rotated them at 5K, tire store says all A/Ts tend to cup. My stock Nitto's cupped at little but were still in decent shape at 45K just a little dry rot on sidewalls, Florida sun.?

best bang for buck off road tire on the market, good performance, no road noise for a tire with this lug pattern, very smooth ride

Looks great, smooth ride, quiet on paved roads

These tires have exceeded my expectations in regards to ride quality and quietness! Quietest tires I’ve ever owned! Would definitely recommend if you’re looking for a great tire that provides outstanding ride quality and quietness!

In the past I usually stuck to BFG, Goodyear, Cooper, or Mickey Thompson. However, with this Jeep being new off the lot; I decided to try something new that seemed to have great reviews. I wanted something that was semi-aggressive, but would handle highway travel well, and be quiet too.

Had these installed with around 1800ish miles on the Jeep; and traded that Jeep off with 54k to 55k miles and same tires. Dealership thought maybe they had 20k miles on them. It was a Jeep so I had all 5 and did 5 tire rotations every 3500-4500 miles. Before I had traded it off last measurement for tread depth was 11/32 to 13/32(I believe the 13/32 was the tire I had replaced due to a sidewall puncture). I road tripped this Jeep to off road areas and then aired down and would air back up afterwards. Then drive it home. The Ridge Grapplers out performed what I could have ever imagined them doing. From the Midwest to out West they were flawless in all types of terrain.

I could see maybe in the South clay muds might give them some issue, but I didn’t get to test them in that type of terrain. I understand the Jeep is a lighter vehicle which probably helped contribute to their long wear life. As any off-road tire they did start to develop a tad bit of noise, but I had a lot of miles on these. With that being said I’d buy these again in a heartbeat.

Couldn't be happier. Aggressive tread design, but quieter than my KO2's. Also lasting twice as long as the KOs. I'm a loyal buyer now.

These tires have been great, they've lasted 80k miles of hard driving and im still at about 4/32 . Only gripe is a little road noise as they have worn(I'm used to it) and loss of traction in some moderate snow. Overall snow driving was good going up highway 80 but it did get squirrelly on occasion. All other conditions have been to my satisfaction. Just Wish they weren't pricey but hey they large tires. I did lose about 7mpg but again to be expected with larger heavy off road tires. I would definitely purchase again if it's in the budget.
