A high quality Competition / race type inner tube suitable for tyre sizes radial 145R10, 165/70R10 and cross ply 5.00x10 and 5.20x10,. These Blockley inner tubes were produced at the request of a number of Mini Cooper Register members wanting the original "race type" inner tube with the bolted in metal valve stem. Our metal valve stems are identical to the original; period items, and are even nickel plated as they were in period, to stop any discolouration.

This extra thick Blockley inner tube was made to compliment our Blockley tyre sizes 145R10 and 165/70R10, but are also suitable for cross ply tyre size s 5.00x10 and 5.20x10. We made our Blockley range of tubes because we wanted something better than what is already available, to supply with our range of Blockley 10 inch tyres. These tubes are of exceptional quality, correct dimension, thicker, and produced by Blockley using the best inner tube material available - Butyl. These Blockley tubes are the best tubes you can buy, and even come as standard fitted with a good quality metal cap to the valve stem.Blockley is the only supplier of these nickel plated metal stemmed Mini tubes, as fitted in period to the Mini Cooper.

Note that Blockley also produce an alternative inner tube manufactured with a standard rubber valve stem which is at a lower price.
