DONNELLY Tubeless Bike Tires

What size do you need?

• Check the sidewall of your current tire; the numbers indicate tire size (rim size and width)
• A tire size of 29 x 2.3 has a 29 in. rim size and a 2.3 in. width
• While the tire diameter must be an exact match with your rim size, you can opt for variations in tire widths though you should consider the min/max widths of the rim

Tire Type 

• Tubeless ready: These tires seal directly on rim of a bike and don’t require a separate inner tube
• Tubeless clincher: This common tire setup includes a tire and a separate inner tube
• Tubular: Less common, the inner tube is sewn inside the casing and glued or taped onto the rim

Bead type

• Wired: The bead—or the edge of the tire that fits into a rim—is made of steel wire so can’t be folded; generally cheaper and heavier
• Folding: These have a flexible Kevlar bead; they can be folded up, making storing and carrying easy
