Whether it's for city cycling or BMX tricks, every discipline has its own kind of tyre!
For Mountain Biking
You should choose a tyre with lugs that are grouped together along the central band and spread out on the sides.
For Urban Cycling
Choose a tyre with few lugs for better grip on roads and paths.
For BMX Street Biking
Choose a tyre with small lugs and a fairly wide section for maximum grip and cushioning when doing tricks.
For BMX Racing
Choose a tyre with more pronounced lugs for better grip on turns.
12, 14, 16, 20 or 24 inches: you'll find the tyre size on the side of your old tyre (in millimetres ETRTO 40-559 or in inches 24”x1.95).
