A superior Blockley inner tube with good thickness as in period, made from the best inner tube material Butyl, for use in tyre sizes 205/70R15 and 205R15. It is interesting to note that when fitting a tube in a 205/70R15 tyre, others for some reason supply you the tube made for a 185R15 tyre. No tubes you can buy are as good as what we produce, which is why Blockley produce tubes, so we can supply them with Blockley tyres when needed.  Note that all Blockley inner tubes come with a high quality metal valve stem cap as part of the price.

These Blockley are a top quality correctly sized tube, with the tyre size it fits written on the side. Not some code which you later find is recommended for many tyre sizes. This is why Blockley has produced its own inner tubes, rather than source them from elsewhere. This Blockley inner tube, suitable for our 205/70WR15 tyre when fitted to wire wheels, weighs 3 1/2 lbs - compare this to a Michelin tube (which is also the fitment for a 185R15 tyre size) which weighs 2 lbs and you will appreciate why Blockley inner tubes are made . . . Tubes are the one thing you really should not be skimping on. There will be tubes that will cost marginally less than a Blockley produced tube, but the Blockley products are in a different league! And remember all Blockley tubes come as standard fitted with a metal dust cap, which will kep the air in the tube even if your valve has a leak if dirt etc gets in, which even the "brand name" tubes being offered by the wholesalers charge extra for!
