I thought I'd reply even though it was a long time ago as it was very good of you to offer, I've fixed it now. At least the garage did, I needed something else done at the same time. Didn't reply sooner as had a bit of computer trouble.
I put it on stands and sort of lay underneath and kick the wheel off with a leg straightening action landing my foot fairly flat on the Tyre. Always works just need to be sure that it don't fall off the stands and squish ya!
