Thanks for that Tony, I've just been scrolling back through the thread and on seeing Bob's old tyre, I thought I'd head off on a tangent.
Years ago I read about runflat tyres. That tyre of Bob's should have had a "bead lock" in it,so the tyre probably was mounted on the rim, after the trucks military service.
I have seen run flats with RF2 and RF3 on them. I recall that one or the other was designed to be able to travel up to 100 miles, once deflated.ie with a bullet hole in it.
I had one on a Dodge rim (900 x 16) that had been driven on for some time with no beadlock (I guess it must have lost its air and they just kept using it)I guess it had been driven in 4wd because the wheel turned so freely in the tyre. Braking can't have been that good either.
Anyhow it was well worn at the bead, but of note was that it was very much thicker at the bead and in the sidewall than Bobs tyre appears to be. (The side wall did not deform under the weight of the vehicle. It weighed about the same as about 3 ordinary tyres.)
So the question is, who has the info on the various types,so that I(and others) might have my memory refreshed (and maybe corrected) on the subject of runflats.
Thanks in advance,
Lynn.
