I Installed Hankook iON HT EV Tires On My Rivian R1S! Here's Why

TL;DR

The Hankook iON HT is chosen for the Rivian R1S because it balances EV-specific efficiency, low noise, long tread life, and all-season capability.

Key Points

• 1.The iON HT is purpose-engineered for heavy electric SUVs and trucks. It addresses EV-specific demands: high torque, heavy loads, and strong braking forces, with a compound prioritizing rolling resistance and durability.
• 2.An 80,000-mile tread warranty makes it exceptional for its class. Hankook also offers a 100-day trial period — buyers can return the tires if unsatisfied, reducing purchase risk.
• 3.Cabin noise is described as whisper quiet, a key selling point for EVs. Because electric vehicles lack engine noise, tire noise becomes the dominant cabin sound, making the iON HT's low noise level a standout feature.
• 4.Efficiency on the Rivian R1S exceeded 2 miles per kWh at 80 mph highway speeds. The reviewer called this impressive for a large 20-inch all-season tire on a heavy electric SUV.
• 5.The reviewer installed the iON HT on both his Rivian R1T pickup and R1S SUV. He tested the tire in varied conditions including sand dunes and track laps, finding grip and breakaway characteristics surprisingly capable beyond everyday driving.
