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 ).

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
