The Bike Trainer Tips 04： How To Chose The Bike Tires For The Bike Trainers
Knobby vs Slick Bike Tires: Which Is Better for Indoor Trainers?
“Knobby” and “slick” refer to the tread of the tires. A knobby tire has more tread, which provides more grip and resistance. This guide explains the differences and helps you choose the right tire for your indoor bike trainer.
What Is a Knobby Tire?
As the name suggests, knobby tires have “knobby” protrusions. The knobs form a pattern or rows and come in a variety of shapes, including squares and hexagons. The knobs provide more resistance and grip on terrain with loose material, such as gravel or dirt.

What Is a Slick Tire?
Slick tires have less tread. The surface of the tires is smoother and grips the road less.
Slick bike tires have less tread. The surface of the tire is smooth, but you may notice impressions in the rubber, such as the manufacturer’s logo or a pattern. The impressions may resemble treads but are only included for aesthetics. The smooth surface of a slick tire ensures that it grips pavement and cement, making it the preferred choice for riding on the road.
Which Tire Should You Use on a Bike Trainer?
As the tire chosen for our bike trainer, we recommend the following:
- For a normal wheel-on bike trainer: We’d better use the slick bike tire to reduce noise and protect the surface of the tire. The smooth contact minimizes friction noise and prevents premature wear.
- For a direct-drive bike trainer: You can accept all kinds of tire types, because it uses electronic magnetic resistance, not friction resistance. The tire does not contact any roller, so tread pattern has no impact on performance or noise.
Final Takeaway
Choose slick tires for wheel-on trainers to keep noise down and extend tire life. For direct-drive trainers, tire choice is entirely up to your riding preference—since there’s no roller contact, knobby or slick makes no difference indoors.
