The Blockley is superior quality thicker Butyl correct dimension Blockley inner tube. These Blockley tubes really are the best tubes you can buy, and are the correct dimension. They even come as standard with a metal cap.

Many years ago a Trade customer asked us to supply a standard tube of better quality in the size 135/145-13, which we did. And some years later when we made the Blockley tyre size 145R13 we decided to go the next step and make something more heavy duty, a worthy product available for using with our 145R13 Blockley tyres for those that needed inner tubes. So for those that need a superior tube, something really good is now available, but does cost marginally more! And because we sell direct to the end user and garages, missing out the middle men Classic tyre wholesalers, we are able to sell this Blockley Superior product at a similar price to anything available elsewhere. You cannot buy a tube this good anywhere else.
