Heads Up: 10.50-16 directional tyres

[Mike Timoshyk]

Great to hear your success Terry. I had the same problem when mounting my tires....I thought I had screwed up when they were laying on the floor 'cause the treads were pointing in different directions....gotta be careful. There is a right and left when setting them up. I had to look 3 or 4 times and then put them up against the truck to make sure.....like measure 3 times and cut once.

Cheers

Mike

After all the efforts you will make to follow a particular set of
MB-C or F 1/2 printed instructions...... at the first show you make....

....someone will walk up and argue you got the tires mounted the wrong way........ or they are the worng size.....!!!!

Wait until you start rotation with your spare tire.....hihihi

Spare tire....oh my gosh I forgot about that....Damn, now I gotta start looking for another rim.

Bob you bring up an interesting point, primarily for LATE HUP owners with the side mounted spare tire, if you still have the original spare tire brackets your new 10:50 X16 tires probably will not fit in the spare tire carrier. In fact new 9:00 X 16 ND don't fit. So before you mount up that 5th tire try one of the others in the spare tire holder.

I learned this the hard way years ago tried to mount a new ND in the rack and it would not fit, in fact even a well worn one can not be fully inflated. Now this may be a peculiarity of my HUP but I've looked at several others and they looked like they would have the same problem. Wonder if this is why you see some HUPs with the lower tire mount brackets for the spare torched out.

Phil,

Grant brought this particular issue to light last month when we got the tires. He has the same problem with his Sigs van. My solution? Keep one of the better 9X16s as a decorative spare. The bigger spare will be kept in the back of my HUP.

I have one more rim to refurbish and then I can mount my new boots. Hopefully Bob found a good source for 9x16 innner tubes!

[Bob Carriere]

I compared an old worn 1940 chevron 9:00 x 16 tire against a modern 9:00x16 US bar thread..... the new tire is at least 3 inches taller...... that's why the new bar thread will not fit the spare tire opening.

It's not a problem on my cab 11... it was designed for run flat tires and NO provision for a spare...... I plan on filling my 10:50 x 16 tires with marchmallows so I can use them as run flats......

Anybody knows how many marchmallow per tire I will need....

38 inches times 3.1416 x 10:50 divided by a constant of 16.009 at the fourth power.... hum..... lots!!!!!

Bob,

Before you run down to the local A&P or Sobey's I would suggest that you assertain whether you calculated for the large size mellows or the smaller colored ones. I suggest using the smaller ones because they will more easily conform the the outstanding curveture of these BIG ASS tires!

cheers

Here are two on my 41 C30 which now has all four new Specialty Tire 10.50-16 chevrons. Did I put them on correctly guys? I took the truck on a thirty mile test run after I had two mounted on the rear. Just in from short four mile test run with all four mounted. First the right rear.

Any tight-wads/frugals want to buy my left over used 10.50-16 tires?

[Mike Timoshyk]

HI Terry,

WELL DONE I have mine on, however, I am a bit envious...you see, my truck still has the engine in my garage....so it will be sometime before my "test run".

All the best for the Christmas season and the New Year

cheers from Windsor

[Bob Carriere]

From your test run......

What speed did you attain...???

Assuming that you do not have snow covered roads like we do.... what song did the tires sing at various speed...???

Do they seem fairly round.... no flat spot or serious out of balance...???

What pressure did you run them at...??

They do look awsome!!!!!!

Like Mike it will be Spring time before I can hear my tires sing on the road.....

BooB

[terry johns]

I had the truck up to 45 mph briefly on a dry road.

If the tires made any noise I could not hear them over the lorry's racket.

Please, someone buy my used 10.50-16 tires. Two like new MITAS and four old assorted WWII.

[Bob Carriere]

I did not realize that you had a cab 11 C30....... very few have survived in North America.

Would love to hear the history of the truck and how you came upon such a vehicle..... my cab 11 C15a feels like an orfan in a sea of cab 13.

Care to swap lies about the restoration drop me a line on the PM so we can exchange emails which would make sending pictures easier.

Bob,

This C30 was orginally restored by Rolf Ask in Norway, who then sold it to Terry.

It appears there might be some of these tyres for sale in South Australia

For reference: NOS 12 ply 10.50-16 tyre, made in Canada by Goodrich - Silvertown (for sale by Dirk Leegwater).

Hi Guys,
I’ve just bought a pair of Coker 10.50x16 tyres and I’m having real difficulty in fitting them to my Bedford OY wheels, has anyone ever fitted them to a Bedford or Austin rim ?, I’d be interested to hear how you achieved it. 😃

[Paul Singleton]

Bob Carriere made up tools to mount tires onto British type military wheels. The thread is in the restoration forum and is titled installing 9:00-16 tires on CMP wheels. The date of the post is 05-01-16. I can’t post a link to it here for some reason, but you should be able to find the post.

[Bob Carriere]

Makes sure the inside of your rim is very clean..... we use a needle gun to remove the larger rust / crust then sandblast and eventually paint them with nice shiny enamel paint which reduces friction.

Snot...... you need some lubricant used by the professional large truck tire shops...... bring a one liter container and beg for a hand full. The stuff is really like snot/mucus and pulls like taffy or stringnie vaseline and is specially formulated for rubber and is not water base so will not cause rust on the rim.

Good luck.

My wheel has been sand blasted and primed and minimal top coat, there does seem to be a slight rise in the steel inside edge which I’m going to take a grinder to, the problem we’ve got is that the tyre won’t even begin to slide over the rim, I’ve got two professional tyre fitters and all the gear, do I need to think about sanding the rubber down on the bead ?. Thanks for all your info, at £290 each I don’t want to mess the tyre up.

Thanks for posting that, today I spoke to Mike who’s got an Austin K30 fully restored in Caunter camouflage, he’s unfortunately having to sell the lorry and she’s on Milweb at the moment, he’s put 4 of these tyres on and said all he did was cut 1/8 inch off the edge of the bead with a very sharp knife, sand blast the wheels and make sure there is no ribs or rising of the steel on the edge where you start to put the tyre on, he did it in his workshop with only fairy washing up liquid for help.
I’ll have a go like this, but with proper tyre slip paste.

[rob love]

Removing some of the inner edge is referred to as "skiving". I have done many many tires successfully like this, however I did get a little carried away on a 9.00-16 the other year I was installing on a limber. I had cut into the large cord under the brad, and on inflation it bulged in that spot. End result was I had to scrap a brand new NDT tire.

The best advise I can offer when skiving, is put on a brand new blade on your utility knife. Once you have skived the one side, use another new blade, or turn the blade around on those knives set up to use both ends of the blade.

I actually have an attachment here at work for compressing the tires onto the rims. It is similar to Bob's, but uses a hydraulic cylinder to do the work. It is a must have when doing run flats (one of which I am doing today ).

[44k6]

I couldn’t at this time load the photos, I ground the inner edge of the wheel halves where they meet and chamfered it a little and cut a little off the bead edge
It popped on very easily.

Hi

Just read this and Bob's thread, and something that I didn't see or missed were I've had better luck mounting tire when the are warm, being more flexible.

Also if the tires have been stacked unmounted it tends to flatten them which changes the angle of the bead. My solution was to put an inner tube in them and inflate them till the beads are slightly wider than the rim and then let them heat cycle couple of times. By heat cycle I mean getting the tire as a unit up to around 80F. This seems to help getting them to go on.

Then on to Bob's tricks.

Cheers Phil
