What’s the furthest you’ve ever driven on a donut tire?

We had a flat in the middle of a long road trip last night around midnight, and literally everything in the state where we could buy a new tire was closed thanks to our friend COVID. Ended up just saying screw it and rode the donut tire about 200 miles through the rain and just getting to the destination. Stopped twice to check the pressure and because it also started storming pretty badly and the lack of traction was killer.
Little donut tire is thankfully pretty durable.

Couple of years. But I am a horrible procrastinator.

With two engineering degrees (from Auburn, la-tee-dah!) why don’t you tell us how far we can expect to safely drive on a donut spare?

200 miles in the rain is just plain dumb. I think they are meant to go no more than 50 miles in dry conditions.
I personally keep a full size spare on all vehicles even if they come with a donut.

Some donuts are almost fullsize and some very small.
I wouldn't sweat 200 miles. Probably keep it under 60mph for saftey measures.

St francisville to baton rouge. Had to stop 2 different times to add air again. It was in the middle of the night on the way home from Missouri. After driving for 11 hours, the last thing you can get fricked with is a flat tire at 1am.
My fault for not making sure the donut was in better shape before the trip. ^

Well I definitely made the judgement that you can make it 200 miles as long as you stop and check the pressure and drive very conservatively

I know you’re being funny, but I will say from what little I have heard about it from my FSAE friends, tire engineering can actually be a much more complex subject than I think a lot of people realize. Full of lots of nonlinear math.

I was driving to Houston on Good Friday in 2011 when I saw pieces of my tire flying from the rear view mirror. I had to pull over and change the tire on the interstate. Having 18 wheelers flying by is not fun. To make it worse, it was the front driver tire.

I know someone in Germany who works for Continental Tire in Germany in R&D.
Smart hombre. PhD and practical. Steelers fan though.

340 miles. Hit a pothole at night on the interstate and blew the tire running about 90mph. Had tire insurance and called them. Said we would have to drive to nearest dealership and park it. They would then have to order a new tire that was a special size and it would take 3 to 4 days to arrive. Said eff it and drove home.

I've never driven on a donut tire.

Lake Charles to BR. Tire blew on the interstate on the way to Houston.
Air was non functioning at multiple gas stations, donut spare was only 15 PSI. Got it filled up eventually and drove back home to BR at 1 AM on a Sunday.

Like 40 miles
Good to know they can last up to 200

We took the kids to Disney in a Ford Taurus with a donut. No problems.

A few hundred miles. Drove to Dallas and had to stop twice to put a few pounds of air in a tire that started slow leaking. Couldn't see a nail or anything. Put on the donut spare and hauled the wheel to a tire shop - they found a hairline crack on the rim causing the air to leak. Couldn’t get a Jag rim anywhere on short notice, so I had to decide whether to drive 550 miles back home on a cracked rim or on a donut. Can’t remember how I split the mileage, but I think I did a 100 or 200 miles on the cracked rim until it started leaking more, then switched to the donut the rest of the way. No way could I keep the speed under 50 on the interstate - did around 65 on it.

Side of the road, and called AAA.

Side of the road, and called AAA. If you ain't gonna use them, why have them?
I've changed several tires on the side of the road, but anymore, Poe's great big black bird has it right.
