180-Stud Ice-Grip 20 x 4 Fat e Bike Tire – Winter Snow & Ice Traction

When roads glaze over and packed snow hides ruts, this 20 x 4″ studded fat tire gives you the grip and confidence to keep moving.

Engineered for winter e-bike use, the tire combines a dense array of tungsten-carbide studs with a cold-flex synthetic rubber compound so you maintain control on ice, slush, and packed snow. The 180 studs are positioned to maximize bite during cornering and braking, while the 4″ tread width increases flotation on soft snow for steadier steering and a smoother ride.

• – 20 x 4″ size: fits 20″ fat-bike wheels, including Rad Runner and other e-bikes that accept 20×4 tires.
• – 180 tungsten-carbide studs: aggressive ice traction for braking and cornering on frozen surfaces.
• – 60 TPI nylon casing: tighter threads for improved puncture resistance and consistent feel under load.
• – Synthetic rubber compound: designed to remain pliable in cold temperatures, preserving grip as mercury drops.
• – Single tire, part number TIR-20 X4 STUD-RAD; UPC 744985453566; packaged dimensions 22.5 x 22.26 x 6.66 inches.

Practical for commuters who need dependable winter performance and for trail riders who push into shoulder-season conditions. The wide 4″ footprint reduces sinkage in fresh snow and helps stabilize heavy e-bike loads, while the stud pattern prioritizes contact patches where you need traction most.

Check rim compatibility and frame clearance before purchase—this listing is for one tire only. Manufacturer-specified construction (nylon + synthetic rubber) and the detailed stud count give you a transparent specification set so you can match the tire to your Rad Runner or any compatible 20 x 4″ fat e-bike wheel.

Confident traction, measurable hardware, and winter-focused materials—this studded tire is a practical upgrade for riders who refuse to let ice dictate their routes.
