9.00-13 Tyres

[welbike]

Hanno, I saw these too yesterday, and asked, they are 150 euro's each, and he has a set of 5, no more.

They are Firestone brand, and came out of Norway.

Hope this helps,

Even though those tyres look to be in good shape, they may have been in storage for 50 years . I would not use them myself unless I could verify that they are of recent manufacture . Those Firestones may have canvas/cotton layers in them, the cotton tends to rot over time. A sudden blow out could have nasty results .

I did by some new MRF 900-13's and also a few new OLYMPICS that were advertised in the Weekly Times by a agricultural tyre dealer

Hi All

That role may best be as display tires for stationary equipment, which is still an important use so I hope everyone will keep their eyes out for finds such as Lex posted. If they turn out to be recent production that is fantastic. If they are NOS and 50 years old great finishing for display purpose.

Mike is pointing out something that any of us who worked with old tires realize just because it looks new proceed with caution. When I first got my HUP it still was wearing some of its original tires but it was very clear that driving on them was not in the cards. Then by chance found set of NOS truck tires looked perfect, but once mounted and inflated to 35 psi and a few miles, 50 to 100, cracks started appearing in the side walls.

Cheers Phil

Those tyres which I spotted at Staman's look like as good as new tyres to me, that is why I posted them here. Better than "new" tyres I have seen which were stored outside for 1 or 2 years.

Of course, in the end it is up to the buyer to determine for which purpose he feels comfortable using them.

Here are two current websites listing 9.00-13 with the same sand pattern tread as the old Olympics.
http://www.bkt-tires.com/it/bkt_prod...gory=sandtires BKT Sandstar 9.00-13

http://www.tyretraders.com.au/index....nd-grip-detail Harvest Sand Grip 9.00-13

Given the low speed of vehicles which used these tyres, or trailers such as the Bofors AA gun, they should be capable, providing you check the load limit per tyre. The BKT website lists an email address in the EU for people in Europe, I think the company are in India. The second link is from Australia.

Better still, it is a Melbourne dealer . The older hay balers use 900-13's . The farmers here all use the modern wrapped round bales , the baling is going on right now in this district

Just rang this company and unfortunately they are only a wholesaler and don't sell to the public

That is disappointing . There should be a local retailer nearby to you , ask them to order some in from that mob . Mike

[motto (RIP)]

Mike has the answer, a local dealer can get them in for you.
An alternative to that would be to contact Leslie's Tyre Sales who are not far from Tyre Traders and deal with them all the time. Leslie's can arrange transport or if convenient I could pick them up and take them to Corowa.
Leslie's phone number is (03) 9311 6815, Mob 0428 558 728 I have been a customer for over thirty years. (No tyre kickers please)
Tyre Traders also had MRF 9.00 - 16 ND Bar Treads to fit British (Blitz) wheels at one time.

Thanks Richard. I wasn't aware another firm also reproduced the Olympic tyres.


What about tubes and "liners"??? I have seen some tubes on Ebay, but the choice of valve style seems to be limited to straight and plastic, it seems? No metal valves and/or angled valves??? And liners? I know Cletrac used a new 16inch liner and cut it to suit the 13inch rim.....but are new 13inch liners available?? or can you do without?

So, what Ply rating is suitable for a 8cwt truck....C8/F8/Morris PU???

Until last week I presumed that the higher the ply rating the better.....but now I noticed that even though the allowed maximum weight increases along with the ply rating....the maximum allowed speed actually goes down.

Any thoughts on this?



It seems that most of the available 9.00x13 tyres (yes, all farm trailer tyres) are rated at 40/50 km/h maximum speed. The 6 ply BKT Sand Star is rated at 65km/h max, with max. 1000kg load.


Available 9.00x13 tyres and available Ply ratings:

Alliance 223
PLY: 8, 10 or 12.......all rated "A8"= 40km/h....but table also mentions 50km/h
http://www.atgtire.com/nl/ShowAllian...ls.aspx?id=734

BKT Sand star (ex Olympic pattern)
PLY: 6, 8, 10............first is rated "D"= 65km/h, the others "A8"= 40km/h
https://www.bkt-tires.com/en/pattern/sand-star

Harvest Sand Star (ex. Olympic pattern)
PLY: 6 ........rated "A8" = 40km/h
http://harvesttyres.com.au/index.php...nd-grip-detail

Trelleborg AF302
PLY: not known........rated "A8" = 40km/h....but table also mentions 50km/h

It seems the old 9.00-13 Dunlop pattern are now being sold as "Harvest" tyres in Australia:
