Pirelli Scorpion XTM AT Tire Test: Desert Off-Road & On-Road Performance

On-Road Impressions: Quiet All-Terrain Performance

• 🎧 The new Pirelli Scorpion XTM AT tires were tested on a 2024 Jeep Wrangler, with initial impressions focusing on on-road noise levels.
• 🤫 The "Elect" version, designed for EVs and PHEVs, was found to be remarkably quiet, making it one of the quietest all-terrain tires experienced.
• 🛣️ Despite being an all-terrain tire, the NVH (Noise, Vibration, Harshness) was impressive, with wind noise from the vehicle being more prominent than tire noise at highway speeds.
• 🛡️ The tires feature a 55,000-mile treadwear warranty, indicating a hard compound designed for longevity.

Off-Road Dynamics in Desert Terrain

• ⛰️ Testing moved to graded, maintained trails with corrugations, where the tires provided good traction despite vehicle instability common in solid-axle vehicles.
• 💡 The tire's tread block organization and sidewall stiffness contributed to a predictable and composed feel around corners, with accurate turn-in and gradual rear-end release.
• 🏜️ In sandy conditions at Dumont Dunes, the tires were tested in various vehicles including a Ford Bronco and a Rivian R1S.
• 💨 During an autocross event, the tires demonstrated good grip and rotation in sand, with the "Elect" version performing well even in a two-wheel-drive challenge.

Electric Vehicle and Heavy Duty Performance

• ⚡ The Pirelli Scorpion XTM AT "Elect" version is specifically engineered for EVs and PHEVs, focusing on low rolling resistance and a quiet ride.
• 🔋 Testing in a Rivian R1S (850 hp, 800 lb-ft torque) with tires aired down to 30 PSI showcased effortless sand dune driving, highlighting the tire's ability to handle extreme torque and terrain.
• 🛠️ The tire's design, including uneven tread blocks and a disconnection groove, contributes to its quiet operation and stability in off-road conditions.
• ❄️ The Scorpion XTM AT is 3-Peak Mountain Snowflake (3PMSF) rated, certifying its performance in snow, slush, and icy conditions.

Key Tire Features and Design

• 🚀 The Scorpion XTM AT features an aggressive tread pattern with a high-void design for superior traction on dirt, gravel, and mud.
