obsolete tyre sizes

[charlie]

I am trying to create a list of tyre sizes no longer available, ideally with details of what machines each size fits.
To start Monro Tiller, Barford Atom 12×3 (3.00×6). Barford Atom 30 5-12 , Trusty Earthquake 3.00×10.

600×22 John Deere model LA.

Hello Charlie.
As mentioned by Dave 6.00×22 have not been made for 30+ years, I tried to locate the whereabouts of moulds several years ago, but it seems they have been destroyed/lost.
Apart from Plowmate, Iron Horse, they also fit David Brown 2D, Coleby shire, Garner 2 wheeler and 4 wheeler, Gunsmith et etc.
Most surviving tyres are now showing their age with cracked sidewalls etc, most important to shield them from the sun.

I think it needs someone to win the lottery and get a batch of 6.00 x 22 made, there must be a market for them, if the price is right.

300 x 6 and 300 x 8, There are plenty of 300 x 6’s on Merry Tiller pneumatic drive wheels, there are some 300 X 8’s around new but they have weird tread patterns.
Pictured are 300 x 6 MT wheels and tyres, they even used Monrotiller alloy rims in the early days…

Firestone make the 600 x 22 tyre in Australia. Had priced two delivered to Ireland, Was coming in at about €400, so maybe wait a little longer for them!!

navanman, thanks for that bit of info. Would probably be worth someone making a bulk purchase, if tread pattern was suitable.

600 x 22 are available in USA as 750 x22 from Miller Tire who also supply the stockists in Australia
They are the remaining stock from the last batch produced by Firestone/Bridgestone and the price reflects this.
This size was fitted as standard to OTA and Monarch tractors but the other optional tyre size originally offered by OTA and Singer was 750 x20 which you can obtain or the grassland tyre 800 x 19.
It is not only the tyre you need to consider but inner tubes as I recently found out and am on the advise of my local tyre specialist experimenting with , some 600 x 19 inner tubes inside otherwise sound 600 x 22 tyres, so far so good

Thanks Franktonpaget,

I wonder could we get a list of people together that want a pair and went for a bulk order. That closed thread pattern looks much better than the open thread on the modern tyres

Just a thought

I saw 8×300 tyres ( for my Autoculto Autogardener) for 30 euros each on this site and the postage didnt seem that excessive. Haven’t bought yet though !

Sorry that was £30 I’d converted from Euro’s

The tyres look OK judging by photos on website
