Heads Up: 10.50-16 directional tyres

[44k6]

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. 😃

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.

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.

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 ).
