History of 10.50-16 tyres

[mlombard]

Hi

So what was the reason for 9.25 x 16 versus 9.00 x 16 surely when they were trying to keep rubber use to a minimum one tyre would have been easier to produce, Was it something to do with weight carrying capacity, they were both off road tyres right, so there would have been no need for different performance characteristics surely. Was it something to do with the 'run flat' requirement on armoured cars etc.

It is amazing what turns up sometimes. This is a copy of a photo in an article in the latest Classic Military Vehicle magazine about the Morris Light Reconnaissance car.

It is the contract card for an order for Mark 1 cars and shows the tyre size required. - Tyres. 9.25-16R.F.

So here we have another vehicle which used the 9.25 x 16 tyre.

Hi Rick

Still begs the question Why, what was so different in the technical specs between a 9.00 and 9.25 tyre.

Whilst whetting me appetite on the tyre history does any of you knowledgeable people have any idea or intel on a source for 10.5 x 16s as will be needing a set soon

The size you are looking for are available this side of the pond, as modern 8 ply ratings with the tractor thread made by Specialty Tires of America. They are distributed by Universal tires and Lucas and currently around $340 US $$$
In the last 10 years the cost has gone form the initial $199.99 US to the current price....... do not wait for them to go on sale!!!!

Note: Wallace Wade Tires of Texas, 10:50 tire distributor, has now closed....no reason available.

On the issue of size.....We have accumulated various old tire casings over the years some are original, heavy as hell, run flat casing dated 1940.

Why the different size????. when you stand up the various tires the 9.25 x 16 found on a HUP is the shortest of all..... sort of a low profile.....followed by the regular 9.00x 16 and tallest the 10.50 x16.... which is a few inches shorter than the 11.00 x 20.

We have all read the importance of matching the circumference of tires on a 4x4 but it is unbelievable the differences height we have observed between 9.00 x16 of the 70s to 90s era Dodge tires...... as much as 2 inches difference in height when mounted and fully inflated between known brands such as..... Firestone, Goodyear, Mohawk, General, etc. are all slightly different........ and if extremes are mixed.... big time binding of the power train.

Some one from the UK must know some distributor channels!!!!

Good Luck

Cheers

We used to get the same thing on the 11.00-20 tires used on the MLVW fleet back when we used bias ply tires. The Firestone and Goodyears were close enough that we could interchange them, but then General tires started to show up which were skinnier and significantly taller. A message came out that the Generals were not to be mixed with the other tires, and that in the future the tires would be sole-sourced to one manufacturer only (not General).

We had the same thing with the old 5/4 ton.....Goodyears and then someone bought a bunch of Cooper super traction. The 5/4 ton was especially picky about tire diameters and pressures. If the stresses built on the powertrain, the transfer case would not kick out of "loc" and eventually the front diff (weakest link) would boil the oil out of it.

It is very important on an allwheel drive vehicle that tire circumferences are the same.

Thanks Bob I better start saving then

You could buy them from one of the American dealers ( https://www.summitracing.com/dom/sea...illocation=dom )
and take advantage of the free shipping to get them to someone with a container heading overseas. I think Issah/Jim Burril mentioned today on the forum they have a container about to go over. Toss them a little towards the shipping, and that way the tires will make it over to the Uk, so you are just looking at domestic shipping from there.

I put a set of those onto the C15TA here at the museum. They really look the part.

Gary,

Other than the tips provided by our Canadian friends, you could also refer to the earlier posting by Tim Bell. Many vehicles in Europe requiring new 10.50-16 tyres today, revert to the Mitas IM-01. They can be bought from several distributors. This thread is also available in 9.00-16, by the way.

HTH,
Hanno

Hi all,
I want to replace the wheels of my CMP scale models with something more decent and it looks the only right way would be to print them in 3D. Can somebody tell me the outer diameter of 10.50-16 tyre? For 9.00-16 it was found: 905 mm.; but I can't find anything on the bigger size.
Thanks in advance!

These are 100% profile tyres so they SHOULD have an outside diameter when mounted of 10.5 + 10.5 + 16 = 37" or x 25.4 = 940mm
