A Blockley dedicated 880x120 inner tube. This is a correct and exact dimensioned product for an 880x120 tyre, which is of unsurpassed quality, with a thick wall section made from the best inner tube material (butyl) so the high pressure air stays inside unlike normal rubber which is porous, so you are not regularly pumping up. These tubes have a nickel plated valve stem, as all stems were in period. Nothing available made today is as good as what we have produced, especially so as this Blockley inner tube is the only dedicated correct sized tube for 880x120 that is available anywhere. Other tube brands sold elsewhere supply a single tube covering a multitude or combination (even referrred to them as "combo" with some brands) of sizes! The only reason for making the Blockley 880x120 inner tube size (alongside the large range of inner tubes we make) is that we also make the 880x120 tyre which requires a correct 880x120 tube, and none exist. This tube can also be used in tyre sizes having 25" diameter wheels, and we are used in tyre sizes 34x4 1/2 and 34x4.

If you look at a Michelin 880x120 tube it is marked for use in tyre sizes "935x135, 895x135, 880x120, 815x105", which shows what big companies can do to cut costs and give their agents the necessary margins to sell this stuff. Note that these are four very different sizes of tube ranging from 815x105 to 935x135, which is why this Michelin is unsuitable. Blockley make one inner tube per tyre because that is how it must be, and how it was originally, but this of course costs more to do and is much more effort. But at Blockley because we produce many tyre sizes we make the tubes in the proper fashion, unlike Michelin who do not even make beaded edge tyres! Yet our Blockley tubes, made in the better material butyl, cost about the same. This is a light in to show you the rip off that is the Classic Vintage tyre and tubes market, while relying on brand name and marketing rather than making the correct item! And why Blockley was started.

At Blockley we make one tube for one tyre on our own dedicated tooling. The super thick Blockley 880x120 inner tube is sized for the 880x120 Blockley tyre, and this tube is only for this tyre size as it should be. But the big companies either don't understand this, or don't care. And since we have pointed this out teh UK agent now lists this tube seperately under the different sizes to give the impression the Michelin is a dedicated size tube - you can decide on how honest this is! So now you know why Blockley had to end up making it's own superior quality inner tube, and why Blockley products are the best you can buy, because we are also end users of the products we produce. And the reason the Blockleys are competitive in price with the alternatives is because we sell our tubes and other Blockley products direct to the end user and garages / restoration shops without the Classic tyre Wholesaler commissions in between.

This 880x120 Beaded edge / clincher inner tubes have an "on centre" nickel plated valve stem with a length of 75mm (3").
