What makes a good BMX tyre?
A good BMX tyre takes high pressure: the higher the maximum, the less it rolls against you on asphalt and in the park. Folding tyres with a Kevlar bead save noticeable weight over wire beads - and weight at the rim is felt more than anywhere else. Width decides the use: narrow and hard for flatland and park, wider for street and trails. More on this in the category FAQ

kunstform Picks from the Tires category
Our history with BMX parts did not start when we opened kunstform in 2003: some of the team have been riding longer than the shop has existed, and most of us are still on a bike today. So we know pretty well which parts we can trust. A kunstform Pick therefore only goes to what we would bolt onto our own bikes: parts where the quality and the value are right, and that you will enjoy for a long time.
