With the trunk being so small, and considering the very few flats I've had in all my years and miles, I opt to take the risk when I travel.  But you are right, there is a chance for a flat among other reasons for being stranded on the side of the road.  I do carry a plug kit, jack, and pump.  Of all the flats I've had, only one involved the sidewall being cut rendering it not fixable, and one other exploding.  The remaining flats were just punctures..

For those that do carry a spare, check the air pressure every so often.  Pretty frustrating havig a flat, then having a spare that is nearly flat.  (no this didn't happen to me, but a close friend, and this was before cell phones)

Dang the bad luck.

Did tire have a slow leak at highway speeds?

It happened to me many years ago.
Fortunately someone on interstate told me about it.
Valve stem was leaking at rim.

When you have a car with bigger than stock brakes, you need a spare that fits over the big brakes.
I loaned him mine, once he got a tow into town.

AAA is a GOOD thing !!
(last time I needed a tow (a local tow) the driver sez..."Hey Mr. Mike...she break down again?!")
The guy knew me by my first name !!!!  Kinda sad...

Sorry, I didn't think about rims not fitting, that never entered my mind.  I was just wondering why everyone would sit around for hours when someone could just loan him a spare to move on.  But, a spare is a must have item on a long cruise.

The spare in the Heap is number 5 of the same wheels that are on the ground.  I have the same problem with stock wheels not clearing the brakes so that seemed like a solid solution.  Yes, it takes up a lot of trunk space but, we are only two when we travel in that car.  The kids are all growed up.  No pet either so Jean has what's left of the trunk plus most of the back seat for "essentials".  I can usually find room to stuff in a small duffel for my needs.

Your last sentence says it all.  Those who fail to plan, plan to fail.

Yes, I could have driven an hour to the failure location, loaned my spare, and then driven an hour back to the show, arrived late and then not find any place to park.
Had it been a breakdown or part failure, or something not totally the fault of the owner, I would certainly have been the first in line to go do that.

My philosophy on bash trips:
Nobody gets left behind. We will do whatever it takes to help Mustangers out. However, it is the duty of every Mustanger to do everything they can (due diligence) to make sure their car is reasonably capable of making the trip. When they don’t do that, it can ruin everyone’s trip. No spare tire that holds air and fits the car is a good example. Wires routed where they get burned going down the road, or loose/missing bolts, or carb return springs attached to temperature sender wires are other recent  examples. If you are joining on a road trip, you owe it to everyone on the trip to make sure you did your due diligence to make it to the destination.
That said, had there not been an alternate solution, yes, we would have come to the rescue. Nobody gets left behind.

Sometimes you read a post but maybe not as well as you should have.  I thought he was in the caravan of Mustangers and there were many cars sitting along the road waiting with him, I was stunned that no one would loan him a tire to keep the caravan moving.  I guess I completely misunderstood the problem.
