Kumho 6302653 255/35R21 101Y HL Solus VA91 EV K-Silent Foam All-Season Tire

The Kumho Solus VA91 EV is an all-season performance tire engineered specifically for electric and hybrid vehicles. Sized at 255/35R21 with a 101Y Heavy Load (HL) rating, this tire is purpose-built to handle the unique demands of EVs — including increased vehicle weight from battery packs and the near-instant torque delivery characteristic of electric drivetrains.

A standout feature of this tire is the integrated K-Silent acoustic foam liner, which is bonded to the inner surface of the tire to significantly reduce road noise transmitted into the cabin. This makes it an ideal fitment for the quiet interior environment that EV drivers expect.

Key Features:

• EV-Optimized Construction: Reinforced casing and compound designed to support the higher static load of battery-electric vehicles
• K-Silent Foam Technology: Internal acoustic foam layer reduces interior cabin noise for a quieter, more refined ride
• Heavy Load (HL) Rating: Exceeds standard XL load capacity, supporting the additional weight common in electric vehicles
• All-Season Performance: Optimized tread compound maintains grip and flexibility across dry, wet, and light winter conditions
• High-Speed Rated: Y-speed rating (up to 186 mph) ensures confident performance at highway and performance speeds
• Circumferential Grooves: Efficiently channel water and slush away from the contact patch for improved wet traction
• Optimized Tread Elements: Maintain consistent road contact across varying temperatures and surfaces

The Kumho Solus VA91 EV in 255/35R21 101Y HL with foam insert is a factory-style replacement or OE-equivalent tire, offering a combination of refined ride quality, EV-compatible load management, and year-round traction in a 21-inch fitment.
