CMP tyre manufacturers

Another Goodyear All Weather tyre, this time a 10.50-16 still fitted to a CMP truck somewhere in the desert.

Hi Hanno,

I have posted some of these before at various places but worth putting them all together in one place.
These are NOS 9.00 x 16" Dunlop Trak Grips made in Australia. Too rare and old to use so I have relegated them to display only. Purchased 5 of them in the nineties from a business 2 km from home.
Note the DD broad arrow on the casing and the "To fit BRITISH wheels"
Hope this is of some interest.

Cheers,

Here's one on a Dodge WC wheel.

Sorry, I missed the main bit. It's a Good Year Sure Grip. Being a Runflat, shes a heavy b_tch! By the way, It says under the "sure grip" "Made in U.S.A."

Lynn's run flat tyre photo reminded me:

Just for interest, here is a run flat insert for a 9.00 x 16 tyre made by Firestone in Canada. It may be of interest to those who never saw one in the flesh.

Had it for sale, but no interest was shown in it so sadly it will go to the recyclers soon. Sometimes you just got to let things go.

Cheers,

Interesting, Jacques.

I always thought a run flat was a single cast tyre with a narrow core.

Wonder how much fun it was getting that insert in and out of a standard CMP tyre?

David the bead needs to be clamped otherwise when the pressure drops to zero the wheel starts to rotate inside the tyre. Some runflats (very heavy) were filled with soft (red) rubber. The metal bead locks in the Dodge wheel (see the thread about modifying CMP rims) has a hinge that folds back on its self (to allow insertion into the tyre) The metal ones probably came along as a result of the rubber shortage. The jeep ones are a pressed steel ring.
