30x3 1/2, 31x4

A 30x3 1/2 beaded edge / Clincher type tyre designed and produced by Blockley with the perfect looking period correct diamond tread pattern, along with a well researched robust tyre carcass and bead construction, designed in house at Blockley. Made on brand new moulds and tooling to correct period specifications. This is the best 30x3 1/2 tyre ever made and should not to be confused with all other brands of 30x3 1/2 tyres on offer from the "old car" Tyre Wholesalers. Whenever Blockley makes a tyre size, you will find prices elsewhere get reduced with offers of free post and free tubes included, free postage and this and that - but just remember what they are selling is just their same old stuff. And if these other brands of 30x3 1/2 tyres and tubes were decent enough, there would be no reason for the Blockley Tyre Co to have produced this 30x3 1/2 Clincher / beaded edge tyre size!

The perfect 30x3 1/2 tyre for the Brass era Ford Model T as well as many other cars.  The 30x3 1/2 tyre size is also referred to sometimes as 30x3.5

This fantastic, well handling and superb quality tyre is the only 30 x 3 1/2 available with correct dimensions, with a larger diameter as the 30x3 1/2 tyre was in period, compared to much of what else is available now which is too small. Do not be put off by our low prices, which is only because we sell direct - which means a superb Blockley 30x3 1/2 tyre costing less than a Wards Riverside tyre in the UK!

Another Blockley high quality tyre suitable for many vehicles of the Edwardian and Vintage era, and a popular fitment for the Ford model T.

This authentic tread pattern super high quality Blockley tyre should not be confused with other brands of 30 x 3 1/2 tires available elsewhere. We were persuaded to make this 30x3.5 size by a well known Ford Model T specialist in the UK because the tyres being supplied were seeming to become even lower in quality. And because we sell our Blockley tyres direct to the end user and garages, our genuinely best 30x3 1/2 tyres even cost less than many of the other offerings such a Wards Riverside, Excelsior, Firestone and all the rest of them. But these 30x3 1/2 Blockleys are perfection and in a different league to anything else available. This is what Blockley Tyre Co is all about, making only the very best of any tyre size we produce. The design of this diamond tread Blockley 30x3 1/2 tyre was made in house from scratch, with new tyre mould and tooling incorporating many improvements over the period diamond pattern design. This means these Blockley 30x3 1/2 will work so much better and last so much longer than what the owners of the cars today have been trained to think is acceptable! Those days are now over. And remember how much more cost effective a tyre is if, apart from the other advantages of quality, looking period correct, and handling nicely, that it lasts so much longer as well.

For the later Ford Model T, Blockley also produce a super high quality 440/450x21, while for the earlier Model T front wheels the beaded edge size 30x3 is also available.

Note also that in period there were also beaded edge / clincher tyre sizes made shortly after called 31x4 and 31x4.45 which used the identical 23" wheel rim as used for the 30x3 1/2 tyre size,offered as an alternative to a 30x3 1/2 tyre, and since these two Clincher type tyre sizes mentioned are no longer available, those needing replacements for these sizes can use the Blockley 30x3 1/2 tyre in their place, especially as our tyre diameter of 31.3",  (795mm) is not far off.

Also note that Blockley found it necessary to manufacture our own high quuality inner tubes, as we were unimpressed with the inner tubes being sold. The Blockley inner tubes are made in a different league to anything Model T owners and others have had to use in the past decades! With our decent wall section, tubes sized correctly, made from the best material for tube manufacture( butyl) and even fitted with a nickel plated valve stem, all this will ensure our tubes will also keep the high pressure in - which is important because beaded edge / clincher tyres need to be run at higher pressure, and you do not want tubes that need pumping up continually.

These 30x3 1/2 Blockley period correct  tyres are the best beaded edge / Clincher tyres ever produced, not only because they are produced to period correct specifications, but also by using improved materials that were unavailable at the time.
