PRESS RELEASE

PIRELLI TYRES TAILOR MADE FOR RIVIAN DELIVER SILENCE ON BOARD AND LOW ROLLING RESISTANCE

SPECIAL VERSIONS OF SCORPION TYRE RANGE CREATED SPECIFICALLY FOR R1T, THE FIRST ELECTRIC PICKUP TRUCK IN THE WORLD, AND R1S, THE ELECTRIC SUV.

RIV IS THE DEDICATED MARKING THAT WILL IDENTIFY PIRELLI’S TYRES FOR RIVIAN; ELECT MARKINGS WILL IDENTIFY EV TYRES.

PIRELLI’S 21-INCH TYRES FOR RIVIAN HAVE A WORLD-UNIQUE SIZE.

New York, 2 November 2020_ – The EV start-up Rivian has chosen Pirelli Scorpion range to fit its highly anticipated R1T pickup, which begins production in June 2021, and its R1S electric SUV.

Pirelli has developed special versions of its Scorpion Verde All Season, Scorpion Zero All Season and Scorpion All Terrain tyres (Pirelli’s dedicated range for SUVs and pickups) to meet Rivian’s specifications, and to enhance the vehicles’ unique characteristics following the “Pirelli Perfect Fit” strategy. Indeed, all Pirelli tyres developed for Rivian have a special marking on the shoulder: RIV and Elect.

“Elect” is the marking that identifies Pirelli tyres for electric vehicles. Tyres play a crucial role in EV performance – they are a key safety, performance, and range optimiser.

Pirelli tyres marked “Elect” offer a number of advantages for electric vehicles, thanks to a specific set of technical characteristics. Low rolling resistance helps to maximise each car’s range. In electric cars, reduction in noise accentuates one of the key advantages of electric driving: silence. Finally, the Pirelli tyres marked “Elect” offer improved traction in line with the intense demands from the transmission. Electric motors deliver the maximum torque available right from the bottom of the rev range, and so they need tyres that can bite into the asphalt instantly.

Pirelli and Rivian co-developed these products over almost two years, and this collaboration has resulted in three special tyres: 20, 21 and 22 inches. In particular, the Scorpion Verde All Season in 21 inches have a very special tyre size, unique in the world, introduced in the industry by Pirelli specifically for Rivian: 275 55R21.

The technical partnership with Rivian underlines the focus of Pirelli on sustainable mobility and American car brands.

PIRELLI SCORPION VERDE ALL SEASON: THE "LOW ROLLING RESISTANCE TYRE

The Scorpion Verde (Italian for green) All Season is Pirelli's eco-friendly Crossover/SUV Touring All-Season tyre developed for the drivers of crossovers, sport utility vehicles and pickups.

The main challenge Pirelli’s technicians had to face to develop a dedicated version of these tyres for Rivian was to meet their low rolling resistance targets.

Pirelli’s engineers worked on a higher-silica compound that decreases the vehicles’ energy consumption. Then, they worked on a dedicated design of the mould, narrowing the tread pattern of the tyres and keeping an optimal footprint pressure distribution. In this case reducing surface-to-ground contact translates into less energy dissipation.

Pirelli’s Scorpion Verde All Season tyres for Rivian are constructed from lighter raw materials that don’t compromise durability or performance. The Scorpion Verde All Season also presents a special size, unique in the industry: 275/55R21.

The Pirelli Scorpion Verde All Season for Rivian increases efficiency and range. It is also designed to combine dry and wet road handling, comfort and year-round capabilities, including all-season traction in light snow

PIRELLI SCORPION ZERO ALL SEASON: THE "GRIPPY" TYRE

If “Verde” in the Pirelli vocabulary defines its environmentally friendly tyres with low rolling resistance and weight, “Zero” definitely indicates its high-performance range.

In particular, the Scorpion Zero All Season tyres are developed for the drivers of powerful crossovers and SUVs, as well as sport-tuned and performance pickup trucks looking for a combination of high-performance capability with all-season utility, including the ability to drive in snow.

For its vehicles, Rivian asked Pirelli to develop an even “grippier” version of its Scorpion Zero All Season tyres. To achieve this request, Pirelli’s engineers introduced nano-composite compounds to ensure maximum grip and stability.

Then they focused on the tread pattern, introducing a dedicated mould with a larger tread width, able to provide more contact area and, consequently, leading to a better handling performance.

All of that, without compromising the low rolling resistance targets needed to support a longer vehicle range.

Making a "unique" tire size is certainly one way to get people to buy the tires from Pirelli. That might make me reconsider which wheel size I want to get.

Good article, and pleased that Rivian are in with Pirelli, a good OEM supplier.

I believe the tyres will utilise the Pirelli Noise Cancelling System PNCS, which uses foam blocks bonded to the inner tyre cavity wall in the tread area. Very effective at reducing resonance of the tyre cavity.

I'm also very interested in how the Verde Low RR Tyres will ride, comfort wise.

This is also the first news I have picked up on about Rivian offering a 22". I believe I've only seen 20 and 21" on the press vehicles?

Keen also to see if a 35" tyre will ever find its way onto R1T or R1S at any point in the life cycle.

Very excited ! Thanks for sharing :)

It will be a shock to many I bet come time to get an OE replacement tire.
I could be wrong though.

A possibility to offset the cost is some green tire credit if one exists. If not most owners will go with it anyways.

I've use Pirellis on a couple of my cars so I'm fine with Rivian using them. However, the unique size is very interesting to say the least, I hope there is some kind of a credit like @eHauler suggested.

It holds true when even buying odd sizes (17, 19, 21) for regular cars too. People avoid it when they can. Here, cost won't be as much of an issue. The R1T and R1T aren't exactly cheap and owners should be walking into this with the expectation of costs in proportion to that.

I've had All-Season Scorpions before as they were OE on my Volvo XC60 and they are a solid choice. However, as is typical for all-season tires, they are good in every season, but great in none. Luckily, Pirelli makes fantastic tires for many purposes. Is anyone else thinking about a set of the 20's for winter and off-roading, as well as a set of 22's for road trips? A second wheel/tire setup is not cheap, but it is one way to get the most out of this game changing vehicle.

It sounds like the two companies are collaborating well to get great choices out there for us.

In reading about the 21' All-Seasons above, I found it a little confusing when reading the following two statements. I guess the conflicting needs for efficiency, traction, and a quiet ride might be a big part of the compromises needed to build a tire that can handle year-round duty.

"Pirelli’s engineers worked on a higher-silica compound that decreases the vehicles’ energy consumption. Then, they worked on a dedicated design of the mould, narrowing the tread pattern of the tyres and keeping an optimal footprint pressure distribution. In this case reducing surface-to-ground contact translates into less energy dissipation."

"Then they focused on the tread pattern, introducing a dedicated mould with a larger tread width, able to provide more contact area and, consequently, leading to a better handling performance."

Again, I think highly of Scorpions, but just as a decathlete ends up with a variety of shoes to wear for all the various events, it would be fun (and yes, expensive) to outfit the R1T with the best skins for the task at hand.

Very true @DuckTruck there's a fine line between efficiency and traction, especially for vehicles this size.

Love the looks of the AT tire. Reminds me of the Durotracs I have on my 4Runner. Hope they perform as well at the Durotracs in snow and ice and offroad!

I do see some similarities with the DuraTracs.

I hadn’t put the pics side by side - thanks for including that @R99. It looks like the Durotrac has a bit more of an aggressive tread, but that’s likely going to be at the expense of noise and power efficiency. I do see a 3 peaks snowflake symbol on the lower left sidewall of the Pirelli, so at least they are snow rated. I’d say the Pirelli’s look to have a good balance of snow / off-road capability and quiet / energy efficient. I like!

No problem at all. It's pretty interesting looking at how similar/different the tread patterns are. I agree the Pirellis do seem to have a good balance to them. It should translate into real-world performance because Pirelli knows what they're doing especially since they're bespoke to Rivian.

What I'm interested to see is what the difference in range will be between using the Scorpio Verde all-seasons and the Scorpio Zero all-seasons.
Adding to that, less road noise.
It should be a big benefit to us getting tires with low rolling resistance.
