The tubeless tyres are better than the tube-type for a simple reason that they are a lot safer. They drastically reduce the chances of tyre burst and also curb the violent reactions from car in case of puncture at high speeds. The only flip side is that they cost a bit more.It is not necessary to have alloy-wheels to fit tubeless tyres. They can be easily be fitted on your existing steel rims – just make sure that these are not rusted from inside and are in proper shape.
