760x90 Inner Tube
The correct fitting super thick butyl Blockley 760x90 inner tube, fitted with a nickel plated valve stem so they look like they did in period. With beaded edge / clincher tubes it is important to make one tube for each tyre size. Or if one tube is used in more than one tyre, that the dimensions are similar. So unlike like a Michelin marked 760x90 tube actually fits the 760x90 tyre size correctly! As far as we know nobody produces a 760x90 inner tube with the correct dimensions, which is why so many people with 760x90 tyres that use their cars properly have trouble!
Designed in house, and produced from our own Blockley tooling, and made from Butyl material (the best material available). You will find that butyl tubes made today are quite thin as the better means suppliers think they can get away with this, but they can't! These Blockley tubes have the thickness of how tubes were made in period, so they will put up with much more abuse, which is how it should be. This is why Blockley makes it's own beaded edge tubes, as we would not want to supply anything we've seen for the 760x90 tyre size we make. We cannot overemphasize that this Blockley 760x90 inner tube should be used when fitting a 760x90 Blockley tyre, the reason being that the dimensions of our tube are correct - unlike other tubes marked 760x90 that are totally incompatible with this size! But we need to wake up and realise that people making these other tubes are not end users of their own products, which explains a lot. And because we sell direct, these tubes are inexpensive compared to the alternatives.
