I use / abuse these tyres on a gravity racing cartie rather than a pushbike... The wheel rim geometry is far from ideal for the tyre... The speeds the cartie runs at can exceed 45 mph, the cornering can be severe. (Far more side loading than a pushbike will apply.) Tyre pressures usually around 50 psi. These tyres proved to be excellent. Handled well and the wear was better than expected.
after the noblies oon my mountain bike and the constant buzzing of them on tarmac ,these are great qiuette and much faster,had them on 2months now,and done about 600 miles,and no punctures,i assume this is because of the kevlar lineing in the tyre, i will change back to my nobblies soon as the frost comes though, i can see them being slippy as only a shallow tread, but thats why they are semi slicks lol, a good fast tyre,
