Understanding Tire Performance

Rad Power Bikes and Kenda have teamed up in 2019 to bring to market a complete lineup of co-branded tires, with increased performance, visibility, and durability. Although we design our bikes to handle everything, there are some differences between tire tread patterns that we would like our customers to know.

For off-road conditions, a general rule is that 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.

 

The RadRover and RadMini (Step-Over) come with two tires that we recommend for light off-road use: the 26 x 4” Kenda Juggernaut (for the RadRover) and the 20 x 4” Kenda Krusade (comes with the 2019 black RadMini Step-Over). These knobby, high volume tires that come on the RadRover and RadMini (Step-Over) are designed to perform well on packed sand, loose gravel, or in light off-road use, but can also help to smooth out potholes or rough road surfaces in the urban jungle.

The 2019 RadMini Step-Thru comes equipped with Kenda Kraze slick tires. These tires are also available for purchase and can be fit on the 2019 black RadMini Step-Over. Slick tires are designed to perform super well in dry, warm conditions on relatively smooth pavement. In those conditions, slick tires can provide more traction, a smoother ride, and less rolling resistance than a similar tire with knobby treads. 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.

The RadWagon, RadCity, and RadCity Step-Thru come equipped with 26 x 2.3” Kenda K-Rad Tires. 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.

Regardless of your tire choice, traction between a tire and the road or trail surface will vary depending on the condition of use. 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.

 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.

NOTICE: If you do not have the experience, skill, and tools to maintain the wheels and tires, Rad Power Bikes highly recommends having a certified, reputable bike mechanic complete those procedures as well as any future adjustments or tuning.
