Two 15-cwt rims I picked up recently have American made “Kant Slip” 9.00-16 W /|\ D tyres FOR BRITISH WHEELS made by Kelly Springfield Tyre Co. on them.

They are a proper NDMS bar grip, and not a retread. I have not been able to find a date on them. The American Kelly-Springfield Tire Company was founded in 1894. It was acquired in 1935 by the Goodyear Tire and Rubber Company, who maintained it as a subsidiary until 1999 when it was integrated into Goodyear North America. It continues today as a major brand under Goodyear. So they could have been made anytime during the past.

Could it be the US supplied tyres for British wheels under Lend-Lease? Or would the US supply European MDAP recipients after WW2 with tyres made for their ex-Canadian equipment?

I had those Kelly tyres taken off the rims and they yielded some nice flaps marked “Goodyear | Made In Canada | for 16” rim” and tubes marked “NCD | W/|\D | Goodyear Made in Canada | 9.00-16 Heavy Duty | Do Not Use in RF Casings”.

Firestone CC Ground Grip

Ford Factory - Good Year Tires

Thanks Mariano for posting this article. I found it very interesting.
How many of you have experienced a broken spring? I have had one (off road in my 3/4 ton WC Dodge) To break 2400 springs in tyre testing indicates some arduous testing. Its hard to imagine all that and the back aches that went with the day to day driving involved.

Dunlop Trak Grip, 9.00 x 16 - Australian made
 

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."

Firestone Run Flat insert 9.00 x 16
 

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.
