The four-door, five passenger R1T pickup is scheduled to start production in June 2021, followed in August by the R1S utility vehicle.
The R1T is slated to have a max towing capacity of 11,000 pounds, accelerate 0 to 60 mph in three seconds and have a range of 400 miles per charge.
It will run on Scorpion Verde All Season, size 275/55R21, which Pirelli describes as an "eco-friendly" all-season touring tire for crossovers, SUVs and pickup trucks.
To meet Rivian's low rolling-resistance targets, Pirelli engineers selected a higher-silica-reinforced compound and paired that with a narrower tread pattern designed for optimal footprint pressure distribution.
Reducing the surface-to-ground contact translates into less energy dissipation, Pirelli said, while the tread pattern itself is designed to provide year-round performance capabilities, including all-season traction in light snow.
Pirelli also is working on Rivian-exclusive versions of its Scorpion Zero All Season tires for the company's crossovers and SUVs, which will have a combination of high-performance capability with all-season utility, including the ability to drive in snow.
For these vehicles, Rivian asked Pirelli to develop an even "grippier" version of the Scorpion Zero All Season line. To achieve this, Pirelli's engineers turned to nano-composite compounds mated with a wider tread pattern for a larger contact area.
In addition, Pirelli will offer a Rivian-dedicated version of its Scorpion All Terrain Plus on/off-road tire, size 275/65R20, for the R1T and R1S.
This model features a symmetric, high-void tread pattern designed to provide smooth and quiet on-road operation along with aggressive looks and "confident" off-road traction, Pirelli said.
