Tire Performance and Replacement Information

Rad Power Bikes tires are designed to be high-performance, visible, and durable and to keep you riding Rad for miles. The tires are developed and sized to work with a specific Rad Power Bikes model or, in some cases, are compatible with multiple of our bike models. 

Click a heading below to learn more about which tires are compatible with which models, the inner tube size each tire requires, and how to choose the best tire for your riding style.

Choose the Best Tire for Your Ride
Off-Road Riding:

If the riding surface is soft enough for a tire to leave behind an impression, using a tire with tread will improve traction over using a slick tire. For any off road riding, we recommend using tires with knobby treads.

City Riding:

Slick tires are designed to perform well in dry, warm conditions on relatively smooth pavement. This is because slick tires have a wide contact patch of rubber where the flat portion of the tire meets the road surface. On pavement, more rubber touching the ground means better grip. However, in cold or wet conditions, riders should reduce speed, increase braking distances, and use caution as they will have less traction than on warm, dry pavement.


Kenda Juggernaut 26" x 4" Tire

Models: RadRover 5 and RadRover Step-Thru 1

Best for: City riding, hard-packed and dry terrain

The Kenda Juggernaut 26" x 4" tire is a knobby, high-volume tire that is designed to perform well on packed sand, loose gravel, or in light off-road use, but can also help the bike ride over potholes or rough road surfaces in the city.

Kenda K-Rad 26" x 2.3" Tire

Models: RadWagon, RadCity 4, RadCity Step-Thru 3

Best for: Dry pavement or hard pack terrain

The Kenda K-Rad 26" x 2.3" tire has an all-purpose tread, reflective sidewall strip, and a puncture-resistant tire liner. These have an inverted tread design, knurled tread surface, and low profile that provide fast rolling and grippy traction-- ideal for commuting and riding with cargo. These tires can handle the bumpiest roads on your commute to work, and occasional light off-road riding on hard-packed gravel and dirt.

Tire traction will vary depending on the road or trail surface and weather. In particularly cold, wet, or icy conditions, or on slippery, soft, or loose surfaces, the tires may provide less traction than on warm, dry, paved surfaces.

If riding in wet or slippery conditions, riders should use caution, reduce speed, and apply brakes more gradually over longer distances to maintain adequate tire grip on the riding surface.

Slightly reducing the tire pressure, within each tire's recommended range, can also help increase the contact patch between the tire and the road surface, which can help maintain adequate grip in slippery conditions.

Caution.png Low pressure may result in loss of control, and overinflated tires may burst. Failure to always maintain the air pressure rating indicated on pneumatic tires may result in tire and/or wheel failure. Do not overinflate or underinflate tires.
