Glad it all came out ok in the end, Tony.
Jill and I had a heart starter blow-out in the right rear tyre on the White Scout Car with a large 1 ton "Humber" trailer attached a few years ago on our way to Canberra for the 60th anniversary of the end of WWII. We were travelling at 55 miles an hour down a steep hill on a left hand bend near Eden NSW. when the tyre blew. We were in a cutting with a bank on each side, higher on the left, and a narrow two way strip of bitumen. I really had to hang on and luckily didn't cross over the white line at any time with traffic coming up towards us. I tow the "Humber' trailer which has White Scout Car wheels fitted with the spare tyre for the Scout Car and trailer mounted on the "A" frame and it is also fitted with get me home bits as well as being a camper for us. Unlike you, we couldn't get off the road and had to change it out on the bitumen with the traffic passing close by. (Jill just added "and the log trucks and wood chip semis heading into Eden").
The biggest problem after changing the tyre was trying to get the now flat tyre back up onto the 'A' frame. Fortunately a truck driver stopped up the road and walked back to assist. There are still some good people in this world.
I don't know how many swerves we did in pulling up but it was pretty scary for a while, the Scout Car had an evil mind of its own..
It is not the first time we have had a scare in an old vehicle. We have a 1923 20hp. Rolls Royce with two wheel brakes on the rear axle only. We had a blow out one day and threw the tyre right off the rim which left us with only one wheel out of four pulling up a 2 ton car and a bare rim sliding down the road. The split rig on the wheel took off and took us about 2 1/2 hours to find, but we did eventually find it on the other side of the road to where we were looking and about 200 metres away.
Drive safe out the folks and be prepared for the unexpected.
Regards Rick.
