It’s not usually us journalists get to kill two birds with one stone. However when Pirelli gave me a hoop and requested me if I wished to check its new all-terrain tire by placing a few of right this moment’s most purpose-built all-terrain automobiles, I knew I couldn’t flip down the chance. Not solely would I get the prospect to lastly put the Ford Bronco and even the Rivian R1S by means of its paces off-road—one thing that I have never finished personally but. It could give me an opportunity to take a look at Pirelli’s newest foot (…wheel?) put on.
It is known as the Scorpion XTM and is the Italian tire maker’s newest contribution to the all-terrain tire market pool. Whereas it would sound trivial, it is really a giant deal, as a result of it is Pirelli’s first-ever actual and true try at making a purpose-built tire particularly engineered to compete with a few of the most iconic A/T tires available on the market. And after hauling ass by means of the desert outdoors Las Vegas and round Demise Valley, California, I can safely say that a few of the business staples have one other competitor to be careful for.
With the intention to take a look at the Scorpio XTM tire, Pirelli flew me and a bunch of journalists to Las Vegas, put us in a bunch of inventory Jeep Wrangler Rubicons, Ford Broncos, and Rivian R1S’s, after which instructed us to drive out of town, into the encompassing desert, by means of Demise Valley, California, and finally to Dumont Dunes on a selected take a look at route. They then accommodated us in a lodge and a few fancy glamping tents, over the course of the 2 days. For detailed perception into testing procedures and knowledge assortment, please evaluation our methodology coverage.

2025 Rivian R1S: The whole lot Confirmed So Far
Rivian’s newest SUV mannequin is on the way in which. The 2025 Rivian R1S second-generation electrical SUV comes with some surprising new updates and options.
Pirelli’s Scorpion XTM Is The First All-Terrain Tire Constructed For Each EV And ICE-Powered Autos
To offer us testers an opportunity to place the Scorpion XTM to the true take a look at, the tire producer gathered a fleet of Jeep Wranglers, full-size Ford Broncos, and a few Rivian R1S’s to slap them onto. As a result of I’ve greater than loads of expertise four-wheeling the Wrangler, I instantly opted to offer the Bronco and the R1S a go.
That is as a result of the Scorpion XTM’s huge deal is that it is the first all-terrain tire line particularly constructed and engineered for each all-electric and internal-combustion-powered automobile purposes. Others design and allocate separate tire traces particularly for electrical automobiles or ICE-powered ones, not each. And thus, the supply of two variations of Scorpion XTM’s—one for EVs and one other for ICE-powered automobiles—makes it fairly distinctive.
Promising such dual-purpose versatility, nevertheless, does elevate some questions and eyebrows. That is as a result of tires for EV purposes are engineered particularly for the bottom potential rolling resistance, all in an effort to spice up electrical driving vary wherever potential. This is because of the truth that EVs are nonetheless somewhat restricted in whole vary on a single cost versus an ICE-powered automobile with a full-tank of refined liquid useless dinosaur juice.
However attempting to attain the bottom potential rolling resistance for the sake of electrical automobile vary additionally, in some ways, contradicts your entire goal of an all-terrain tire. And that is as a result of all-terrain tires are all about maximizing grip on each paved and unpaved surfaces. So, in idea and precept, an all-terrain tire designed for EVs is a little bit of a conundrum.
Low-rolling resistance means decreasing the quantity of drag, or traction, to the best diploma to make them glide over a floor and maximize driving distance. Typical all-terrain tires, quite the opposite, are particularly meant to maximise traction or grip, which thus, will increase drag. As a result of, fairly merely, the extra one thing grips a floor, the extra resistance it places up from greater quantities of friction, and thus, the tougher it’s to maneuver. Whereas, when one thing grips a floor much less, the much less resistance it places up from decreased friction, and the better it’s to maneuver, as a precept of physics.
So how does one make a tire do each? Properly, no matter Pirelli did might be the tire equal to witchcraft, because the Scorpion XTM might be probably the greatest and most versatile all-terrain tires I’ve personally skilled but.
Pirelli’s Scorpion XTM Allowed The Ford Bronco And Rivian R1S To Attain Their True Off-Highway Potential
Inside the first 50 or so miles of our deliberate 150-mile-ish highway journey, the very first thing I observed in regards to the XTMs was how insanely quiet and easy they had been, for an all-terrain tire. A/T tires usually include a bunch of compromises over purpose-built on a regular basis highway tires.
“These tires do not appear to exhibit the ‘knobbiness’ on the highway that you just get with another all-terrain tires,” my driving companion first famous as probably the most obvious preliminary statement.
As a result of A/T tires are much more strong and beefier, with thicker rubber compounds, considerably extra aggressive tread patterns, and different reinforcements within the identify of grip and power, their on-road efficiency usually suffers. The result’s elevated highway noise from what’s known as “tire roar,” stiffer rides, and general much less refined experiences.
These aggressive shoulder beads that you just see on most A/T tires? Yea, these generate a ton of highway noise and end in a type of “droning” or vibration noise on pavement at pace. However shockingly, the Scorpion XTMs exhibited none of that, or any of the standard A/T tire drawbacks.
A serious feat, particularly contemplating that Pirelli USA’s staff of engineers mentioned that they had a helluva time attempting to persuade the corporate’s engineers in Italy on design and make a correctly good all-terrain tire. And that is as a result of off-roading is not as prevalent as a pastime in Italy, versus in America.
As an alternative, Europe’s boot is all about sunny, stunning climate, completely easy pavement, and curvy roads on the Riviera, if not pace and efficiency on racetracks. That is the corporate that brings us Lamborghini, Ferrari, and Alfa Romeo, or a few of the greatest road-going automobiles the world has ever seen, amongst many different issues. 4-wheeling and all-terrain tires aren’t actually their specialty, which is what makes the Scorpion XTMs that rather more spectacular.
I imply, might you solely think about the type of dialogue that occurred between Pirelli USA’s engineers and the staff in Italy…?
Gripping Efficiency With Barely Any Compromise…Oh, And The Ford Bronco And Rivian R1S Are Extra Badass At 4-Wheeling Than I Anticipated
What even grew to become extra obvious and apparent was how nicely the vans and tires carried out when the paved surfaces disappeared. From the silty sands of Demise Valley, to a few of the rockier filth trails within the surrounding areas. The Scorpion XTMs confirmed no indicators of compromise within the off-road division both, regardless of performing exceptionally nicely on the highway.
To actually put the Scorpion XTM’s to the take a look at, as soon as our convoy of Wranglers and Broncos made it to the ultimate in a single day cease simply south of Demise Valley on the world-famous Dumont Dunes, the Pirelli staff carved out a half-mile-long sandy autocross course, the place we had been allowed to let ‘er rip on the whims of our ability set.
And yours really totally gave the Bronco a beating by means of the course a number of occasions, the place the tire clearly enabled unimaginable quantities of management and grip, and even in components of the encompassing dunes. Not solely was I impressed with the Scorpion XTM’s efficiency within the rocky and sandy bits. I lastly obtained to personally expertise the Bronco’s true off-road functionality for the primary time. I do know the Bronco’s been round since 2021 and the four-wheeling neighborhood has confirmed its rugged capabilities and sturdiness since launch. It was a primary for me, nevertheless.
Having extra expertise in Wranglers, by way of devoted and purpose-built off-roaders, the Bronco proved to me how tough-as-nails it’s out in Demise Valley as its direct rivals. Particularly for the reason that Broncos we piloted had been all loaned to Pirelli by means of a Vegas-based rental agency, and all of the models within the take a look at fleet had no less than 30,000 laborious miles on them, if no more.
Rounding off the expertise was a 20-minute loop round Dumont Dunes in a Rivian R1S, which was a really distinctive expertise in itself. I used to be curious to see how totally different it might be to take a rugged EV just like the R1S off-road, particularly given its measurement and heft. Primarily, heft, since an R1S weighs virtually as a lot as a planet on wheels at an eye-watering 7,068 kilos.
It sounds just like the type of heft that will make you sink and get caught in a topographical floor equivalent to sand dunes, proper?
Nope. Not solely did the R1S glide by means of Dumont Dunes like every other succesful off-roader. It was additional bolstered by the epic rubber that’s the Scorpion XTM. Probably the most distinctive and most considerable a part of driving the R1S across the dunes was how easy it was, so long as one workouts correct throttle management. And that is as a result of the R1S’s aggressive regenerative braking system might actually put you in a pickle with such a heavy, cumbersome automobile on a floor like sand dunes with excessive dangers of sinking.
However with correct footwork, the R1S is a really succesful, if not seamless off-road automobile. Regardless of the worry of the regenerative braking system performing too aggressively and inflicting the three.5-ton R1S from digging into the mushy sand, the system really made for straightforward one-pedal off-roading on a few of the tougher and extra angled surfaces across the dune. It was basically an EV’s equal to a low-range gearbox on a standard ICE-powered four-by-four.

How The Ford Bronco’s Comeback Modified The SUV Panorama In The 2020s
The re-introduction of the legendary Ford Bronco modified the overrun SUV market, here’s what its comeback did for the SUV phase throughout the 2020s.
I Stroll Away Impressed With Each The Scorpion XTM, And The Bronco And R1S
Upon conclusion of the testing, I walked away not simply impressed with the four-wheeling efficiency of the Bronco and R1S out in the midst of the sandy desert, but additionally with Pirelli’s new bag. From the Scorpion XTM’s versatility and efficiency each on and off-road, it proved a transparent winner from simply how flexibly it carried out on the 2 automobiles sampled.
However extra so, off-roading the Bronco and R1S instilled a brand new stage of belief in each platforms having by no means skilled them personally till now. I can now see that the Jeep Wrangler is not the one go-to off-roader because the Bronco actually provides a brand new viable option to the choice of devoted four-by-fours.
The R1S, nevertheless, has me much more curious as to the place the four-wheeling scene might probably go together with its capabilities, and it tells me that the way forward for leisure off-roading is not going wherever if the age of full electrification really takes over.
