The Kenda K-Rad 20" x 3.3" tire features an all-purpose tread, reflective sidewall stripe, and K-Shield puncture-resistant tire liner intended for e-bike use.
The K-Rad tires were a replacement for the original tires on a Rad e-bike. I haven’t ridden much on the new tires but while installing them, I noticed they were much beefier than the originals and would certainly handle goat heads far better than the original tires. Goat heads led to the demise of the originals. . . Hundreds of flatheads!
